Three cases of measles has been confirmed in Wisconsin in recent weeks, the latest involving an out-of-state traveler who traveled through Milwaukee Mitchell International Airport to Walworth County on Jan. 29. 

Milwaukee Health Commissioner Michael Totoraitis said during a news conference Tuesday that there were six individuals on the flight from the city of Milwaukee who may have been exposed as well as others.

“We have been in communication with those (six) individuals, and there’s also likely other contacts from the airplane that we do not have,” he said.

Measles is a serious disease that can cause high fevers and a spreading rash and lead to life-threatening complications such as pneumonia. 

Lindsey Page, director of immunizations and communicable disease with the Milwaukee Health Department, said measles is highly contagious and the risk of it hitting the city is real. 

Extremely contagious but can be prevented

According to the Wisconsin Department of Health Services, measles can spread from person to person through the air from coughs or sneezes. The department states that measles is so contagious that 90% of unvaccinated people who are around someone who is infected may also be infected.  

Page said the measles, mumps and rubella, or MMR, vaccine is highly effective at preventing the spread of measles. Still, vaccine rates in the city are below the recommended rate for herd immunity. Herd immunity for measles is reached when 95% of people in the community have the MMR vaccine. 

“It certainly poses a threat, which is why we’re obviously emphasizing the vaccination, which is key in preventing disease from spreading before it starts,” Page said. “The measles vaccine is one of the most effective and well-studied vaccines ever used.”

Three-fourths of 6-year-olds in Milwaukee have received both recommended MMR doses, according to the Milwaukee Health Department. Among 18-year-olds in Milwaukee, that number increases to 88%. 

The Milwaukee Health Department and Milwaukee Public Schools are working to get residents access to vaccinations to increase those rates and keep them safe. 

According to the International Vaccine Access Center, childhood vaccination rates in the U.S. have declined, and only 10 states had MMR rates above 95% during the 2024-25 school year.

Vaccination rates low in many Milwaukee schools

Of the 152 Milwaukee public, private and charter schools with available vaccine data, only 11% have reached herd immunity levels of 95% for the MMR vaccine, according to data from the Washington Post. 

Only two Milwaukee Public Schools for which data was available, Highland Community School and Cooper Elementary School, had an MMR vaccination rate of 95%.

Just 7% of Milwaukee schools have a 95% immunization rate for all required vaccinations.

Milwaukee Public Schools notifies families if immunization records are missing or incomplete, and students may be excluded from school if requirements are not met within a reasonable time, said Stephen Davis, MPS media relations manager. 

Students are allowed to attend school while families work to get their required vaccinations or submit a valid exemption as allowed by state law, Davis said. 

Wisconsin DHS allows vaccination exemptions for medical, religious or personal conviction reasons. Davis said exemption requests in the district have fluctuated from year to year.

Page said the Milwaukee Health Department runs vaccine clinics inside select MPS schools at the beginning of the school year. Students take home vaccine consent forms for parents to sign so those students can get their required immunizations in school. 

In the near future, the department will set up targeted clinics in schools with low MMR vaccination rates, Page said.

MPS prepares for potential measles cases

MPS is monitoring measles in the region and maintains regular communication with local and state public health partners, Davis said. 

Davis said the district has an infectious disease response plan, which the district reviews periodically and updates as public health guidance changes. The district last reviewed the plan in 2025. 

“While no increased risk has been identified within our schools at this time, we are remaining vigilant and prepared to respond if conditions change,” Davis said. 

If a case of measles is identified in the city, Davis said MPS would implement its response plan, including coordinating with key staff and reinforcing illness reporting procedures.

“Schools would follow established exclusion, cleaning and notification procedures in accordance with public health guidance,” Davis said.

Where can I get vaccinations?

The Milwaukee Health Department and the Wisconsin Department of Health Services offer several resources to check your vaccination status and access free vaccinations. 

Page said you can check your vaccination status with your pediatrician or doctor, look up your status on the Wisconsin Immunization Registry or contact the city Health Department at 414-286-6800.

Page said the Health Department offers free MMR vaccines to all residents at three immunization clinics regardless of age or insurance status.

These clinics also offer other vaccines, available for free for people without health insurance. Eligibility for certain vaccines depends on factors like age, and some vaccines are not always available.

Check vaccine availability by calling 414-286-8034.

Measles is in Wisconsin. Are Milwaukee schools vulnerable? is a post from Wisconsin Watch, a non-profit investigative news site covering Wisconsin since 2009. Please consider making a contribution to support our journalism.

With three measles cases in three different Wisconsin communities since New Year’s Day, the state could be vulnerable to a larger outbreak, according to public health experts.

“We’ve gotten three cases in the state of Wisconsin so far in 2026, and there’s been many years in which we had zero,” said Dr. Joe McBride, a pediatric infectious disease physician at UW Health Kids and assistant professor of medicine at the University of Wisconsin School of Medicine and Public Health. If the cases spread, “those are incredibly, incredibly difficult for us to slow down and to prevent.”

“There may be only three people with measles, but the cases are occurring in three different places,” said Ajay Sethi, director of the Master of Public Health Program at the UW medical school. “These are three separate public health responses, and that is significant given the potential for spread to others from just one person with measles.”

In January, state health officials reported a measles infection in a Waukesha resident. This month, measles infections have been identified in Dane County and in a person who traveled through Milwaukee County’s Mitchell International Airport to Walworth County. The Wisconsin Department of Health Services has also identified possible locations when other people might have been exposed in the Dane County and Mitchell Airport cases. All three were described as connected to travel. 

“It’s good, in that they don’t seem to be related, and we don’t see an outbreak,” McBride said. “But it’s also bad because that means there’s a lot of measles,” he added. “It’s kind of a tinderbox, and we have large cohorts of our population who are not immune.”

The year 2025 saw a resurgence of measles nationwide, approaching 2,000 cases, Stateline reported in December, with outbreaks in Texas, Arizona, South Carolina, Utah and New Mexico.

Sethi said an August 2025 cluster of cases in Oconto County started with a case in St. Croix County in someone who was visiting from out of state. Across Wisconsin in 2025, “Ultimately 36 people got measles, and two of them needed hospitalization,” he said.

‘Incredibly infectious’ illness

Although most widely known for its trademark rash, the measles virus “is a respiratory virus, just like really any other cough and cold virus that we think about,” said McBride. “However, it’s incredibly, incredibly infectious.”

The virus is airborne, McBride said, and can hang in the air for up to two hours. In one landmark case, at the 1991 Special Olympics at the Minneapolis Metrodome, a participant on the field had measles, McBride said, “and people who were susceptible to the infection got the infection who were sitting in the upper deck.”

Vaccination is the primary tool to stop measles, and in Wisconsin as well as in much of the U.S. vaccination rates are below the 95% that public health practitioners say allows for widespread “herd immunity.”

The measles vaccine is usually given in combination with mumps and rubella vaccines, first at the age of 1 with a booster by the time a child is 5.  

Some people aren’t eligible for the vaccine, either because they’re younger than 6 months old or because they have a compromised immune system due to another illness.

“It’s a live vaccine, and live vaccines have the potential of causing infections in people who are immune-compromised, like bone marrow transplant recipients or a patient with AIDS” or people on medications that suppress the immune system, McBride said.

That makes it even more important for people who are eligible to get the vaccine, public health experts say.

A national map produced by ABC News in collaboration with Boston Children’s Hospital, Harvard Medical School and Icahn School of Medicine at Mount Sinai in New York shows that none of the counties in Wisconsin has as many as 90% of  5-year-olds fully vaccinated for measles.

The lowest rates of measles vaccinations for that age group are in Portage and Columbia counties, with fewer than 60%. A cluster of counties around Oshkosh have vaccination rates in the low 60s; another cluster around Eau Claire in the mid-60s, and Milwaukee, Racine and Waukesha counties have vaccination rates in the high 60s. In the rest of the state, vaccination rates for children 5 or younger are in the range of 70% to more than 80%.

“The decision to get vaccinated is still very nuanced,” Sethi said — influenced by a variety of factors. Those include complacency, which may lead people to dismiss the need for a vaccine, he said. Other factors include how convenient it may be to get the shot, confidence in the vaccine’s effectiveness and a sense of community responsibility.

HHS shift, CDC silence

One source of shakier confidence has been a shift at the U.S. Department of Health and Human Services and the Center for Disease Control and Prevention (CDC), in the agencies’ stance on vaccines under HHS Secretary Robert F. Kennedy Jr., who had a history of anti-vaccine campaigning for years before his appointment.

Kennedy has made some appeals for people to get the measles vaccine, and in an appearance on CNN Sunday, Dr. Mehmet Oz, director of the Centers for Medicare & Medicaid Services, urged viewers, “Take the vaccine, please.”

But researchers at Johns Hopkins University in a report published in December documented that amid the 2025 measles surge, CDC social media accounts “have gone quiet, creating a ‘void’ in online health communication. In this vacuum, measles messaging has been dominated by news media rather than expert health authorities, resulting in polarized and potentially inaccurate information.” 

By the year 2000, measles vaccination had become so widespread that the U.S. was identified as having eliminated the disease. Canada, which also had that status, lost it in 2025, and the U.S. appears to be on the verge of losing it as well, Sethi said.

Yet the measles vaccine is both extraordinarily effective and essentially the only weapon against the virus.

“There isn’t any kind of other medicine that can abort it,” McBride said. “It is completely dependent on either preventing it or having natural infection and supporting the individual through it.”

The infection itself can be extremely serious, however, he said. In addition to fevers, cough and the rash, which is painful, secondary complications can do much more bodily damage. Those can include bacterial infections, pneumonia, vision and neurological damage and cardiovascular system harm as well.

In about one of every 1,000 cases, a delayed neurological condition can arise 10 years after a person is infected “that is completely fatal,” McBride added. Among the hundreds of cases across the U.S. now, “there certainly is somebody who’s walking around today who will be dead of measles in 10 years, who doesn’t know it. And that’s incredibly scary.”

People born before 1957 are more likely to have natural immunity from having been exposed to measles in childhood. “After 1957 we can’t really make that claim for people,” McBride said. “And so our immunity is dependent on vaccine status.”

People living in Wisconsin can look up their immunization status on the Wisconsin Immunization Registry, McBride said. Some people’s records might be incomplete, either because they received a vaccine in another state or because they got a vaccine before 1999, when the registry was launched. Earlier vaccines were logged on paper by health providers, according to the Wisconsin Department of Health Services.

Interest in the MMR vaccine appears to be rising. News reports and public health announcements drawing attention to recent measles cases and the importance of the vaccine “certainly raises new awareness and attention to it,” he said.

More patients are asking about the shot and more doctors and nurses are asking whether there needs to be any changes to the current vaccine schedules recommended by the American Academy of Pediatrics or the state health department.

McBride said the current cases in Wisconsin don’t point to any change in those recommendations, however. For health care providers, “The most helpful interventions would be to evaluate your patients and make sure they are up to date with the measles vaccine.”

States that were leaders in childhood vaccination before the pandemic are among those losing ground as exemptions and unfounded skepticism take hold, encouraged by the Trump administration’s stance under U.S. Health and Human Services Secretary Robert F. Kennedy Jr.

Expanded exemptions for parents are likely to drop both Mississippi and West Virginia from the top national rankings they held before the pandemic, according to a Stateline analysis of federal data. Other states like Florida, Idaho, Louisiana and Montana also are pushing the envelope on vaccine choice.

At least 33 states were below herd immunity in the 2024-25 school year, compared with 28 states before the pandemic in 2018-2019, the analysis found. Herd immunity refers to the percentage of people who must be vaccinated or otherwise immune from an infectious disease to limit its spread.

Research shows that in the case of measles — a highly contagious disease — states need to maintain at least 95% vaccination rates to protect people who can’t get vaccinated. Other diseases have similar herd immunity rates. People who can’t be vaccinated might include infants too young to receive certain vaccines and those with underlying health conditions.

Misinformation and expressions of distrust from influential leaders have an effect on parents, doctors say, as do new state exemptions making it easier for families to avoid the vaccines.

Some people who never questioned vaccines before notice a national debate and get confused, said Dr. Patricia Tibbs, a pediatrician in rural Mississippi and president of the Mississippi chapter of the American Academy of Pediatrics. New religious exemptions may already be fueling an increase in pertussis, also known as whooping cough, in Mississippi, she said.

“If they hear something about it in the news, then it must be right, they think,” Tibbs said. “We’re just following the guidelines and informing patients that this is a scientific discussion. Nothing has changed about the science. But people who don’t know science are making decisions.”

Under Kennedy’s leadership, federal support for vaccination has continued to slide, and many states have joined a movement to set their own course by following more science-based recommendations from doctors. On Jan. 26 the Governors Public Health Alliance, a group of 15 Democratic governors, endorsed child and adolescent vaccination standards from the American Academy of Pediatrics rather than the federal government.

Federal health officials in Trump’s administration have cut back the number of recommended vaccines. The chair of a vaccine advisory committee, pediatric cardiologist Kirk Milhoan, suggested in a Jan. 22 podcast that individual freedom was more important than protecting community health with vaccines, even for measles and polio.

New leading states

Before the pandemic, Mississippi and West Virginia had the highest kindergarten vaccination rates in the nation, according to the Stateline analysis. About 99% of kindergartners in each state had their required vaccinations before entering public schools in the 2018-2019 school year.

In the latest statistics for the 2024-25 year, Connecticut gained the No. 1 spot, followed by New York and Maine. Those states have reined in exemptions to school vaccine requirements, while Mississippi and West Virginia have begun to allow more exemptions.

West Virginia didn’t report vaccinations to the federal Centers for Disease Control and Prevention for the 2024-25 school year. The state department of health told Stateline the data wouldn’t be available until later this year.

But the state is likely to be pushed out of the top 10. Republican Gov. Patrick Morrisey issued an executive order a year ago giving parents the right to ask for religious exemptions. To date, the state has approved 693 such requests for the current school year, spokesperson Gailyn Markham wrote in an email. That alone is enough to shift the state’s ranking significantly.

Stateline computed an average of required kindergarten vaccination rates to compare states. The analysis uses 2018-19 as a pre-pandemic baseline because a large number of states did not report the information in 2019-20 in the chaos that followed the early COVID-19 spikes and school closings.

A January study published by JAMA Pediatrics found increased vaccination rates among kindergartners in states that had repealed nonmedical exemptions, suggesting the repeals “played a role in maintaining vaccination coverage in repeal states during a period of heightened vaccine hesitancy.”

Requirements and exemptions

All 50 states and the District of Columbia require students to have certain vaccines before attending public school. They also all allow exemptions for children who cannot receive vaccinations for medical reasons, and most states allow nonmedical exemptions, often for religious or sometimes personal reasons. But Florida Republican Gov. Ron DeSantis’ administration has proposed dropping all requirements, and Idaho enacted a 2025 law allowing vaccination exemptions for any reason. Idaho had the lowest rate of kindergarten vaccination, about 80% in the 2024-25 school year before the law took effect in July last year.

Louisiana in 2024 enacted a law dropping COVID-19 vaccine requirements for public schools, and the state has opted to halt publicity about flu vaccination and end public vaccine clinics.

A Florida bill that progressed out of committee in January would maintain school vaccine requirements but expand exemptions to include “conscience” as well as medical and religious reasons.

Dr. Jennifer Takagishi, a Tampa pediatrician and vice president of the Florida chapter of the American Academy of Pediatrics, said the organization opposes both the DeSantis administration proposal to revoke vaccine requirements and the bill that would expand exemptions. Florida’s kindergarten vaccination rate fell from 94% before the pandemic to about 90% in 2024-25, according to the Stateline analysis.

“They’re ignoring the 90% of their constituents who want vaccines and want to stay safe,” said Takagishi. “The legislators are listening to the louder voice of those who want to oppose vaccines instead of the majority. We also know that there are teachers in the school system and school nurses who are fighting this because it puts them at risk.”

All states except Montana report kindergarten vaccine statistics to the federal government. Montana enacted a 2021 law making vaccine status private and unavailable for statistical reports, over the objections of medical experts. The law also made medical exemptions easier for families who think their children have been injured by vaccines.

Dr. Lauren Wilson, a pediatrician and then-vice president of the Montana chapter of the American Association of Pediatrics, said in a hearing that the law would make “vaccination information unavailable for responding to and mitigating public health emergencies.”

“Vaccines have saved millions of lives. I personally have seen cases of tetanus, pertussis, measles and meningitis and the tragedies that these mean for families,” Wilson said in her testimony.

A 2023 court order forced Mississippi to accept religious exemptions. West Virginia allows religious exemptions following the governor’s order last year.

Tibbs, who practices pediatrics in rural Jones County, Mississippi, said she has been seeing more pertussis than usual, and thinks vaccine exemptions could be a factor.

In Mississippi, which reported 394 religious exemptions for the 2024-25 school year, overall rates remained high enough that year, at about 97.8%, to ensure “herd immunity” in most cases.

Mississippi has granted 617 religious vaccination exemptions for kindergartners this school year, about 1.8% of the class, according to Amanda Netadj, immunizations director for the state health department. About 96.3% of kindergartners have all required vaccinations this year.

But the state’s whooping cough cases last year were the highest they’d been in at least decade, and in September health officials announced an infant had died of the disease — the state’s first whooping cough death in 13 years.

“We do have a lot of people getting the religious exemption,” Tibbs said. ”But still, on any given day, the majority of my patients will still get their vaccines. We are keeping our fingers crossed that the numbers stay high enough.”

Wisconsin’s first case of measles in 2026 was confirmed this week in a Waukesha resident, state health officials have reported.

The Wisconsin Department of Health Services (DHS) reported that the individual’s illness was “related to international travel.” Citing privacy concerns, the department withheld all other information, including demographic information about the patient and whether or not the individual was vaccinated.

DHS and the Waukesha County Health and Human Services department are working to identify and notify people who might have been exposed to the individual. DHS reported that no public places where others might have been exposed have been identified.

The illness was the first confirmed case of measles in Wisconsin for 2026, according to DHS, and was confirmed by the Wisconsin State Laboratory of Hygiene. 

The department is urging state residents to get a measles vaccination if they haven’t done so already.

A report in mid-December from the federal Centers for Disease Control and Prevention found there had been 1,958 confirmed cases of measles in 43 states last year through Dec. 16, and a sharp increase in December raised concerns for holiday travelers, Stateline reported.

State health officials are urging Wisconsin residents to check their vaccination status “to make sure they are protected from measles.” The department is advising people with winter vacation plans to check measles activity in the places they plan to visit and confirm that they and any traveling companions are up to date on needed vaccines.

Aborted fetal cells are not used to manufacture the measles, mumps and rubella (MMR) vaccine today, though the original rubella vaccine was made using human fetal embryo fibroblast cells obtained from two elective abortions in the 1960s.

The rubella vaccine is one of many vaccines that use the cell lines from those aborted fetuses, meaning they descend from the original fetal cells, but are not taken directly from new fetal tissue. These cells were chosen because the womb’s sterile environment does not contain the viruses often found in animal cells.

During the manufacturing of the MMR vaccine, the vaccine virus is purified and cellular debris and growth reagents are removed, breaking down trace DNA until there is none or almost none left.

Most of the major world religions that oppose abortion, including the Roman Catholic Church, have deemed vaccines permissible to prioritize the health of pregnant women, children and the wider population.

This fact brief is responsive to conversations such as this one.

• Measles was once declared eliminated in the U.S., but it’s spreading again. And now it has reached Wisconsin. State health officials on Saturday announced nine cases in Oconto County — the first infections confirmed in the state this year.
• Older Wisconsin residents recall painful and disruptive bouts with childhood measles during the pre-vaccine era. Some are still affected, such as those who lost their hearing as a result. 
• Of the estimated 3 to 4 million Americans infected each year before vaccinations, an estimated 48,000 were hospitalized and 400 to 500 died.
• Health professionals are preparing to recognize the signs of a disease they’ve rarely, if ever, treated — and to respond to potential outbreaks.

The measles started like a typical childhood illness for Dorothy Thompson — with just a runny nose. But she soon developed itchy red blotches across her skin and a fever so high doctors feared it could cause brain damage. She was just 5 years old, but decades later, some of her memories remain vivid.

“It was so horrible,” recalled Thompson, 72, of Richland Center. “I would never wish it on anyone.”

In the years before a measles vaccine became widely available in the 1960s, Thompson’s experience was not uncommon. Nearly every child in the United States caught measles before age 15. What many considered a normal part of childhood was disruptive and even deadly. It wasn’t unusual for students to go home from school sick. In hundreds of cases each year, they never returned. 

After vaccine advances eliminated the virus in the U.S., measles is spreading again. More than 1,300 measles cases have been confirmed across 41 states, the latest being Wisconsin. 

The state Department of Health Services on Saturday announced it confirmed nine measles infections in Oconto County — the first in Wisconsin this year. 

To understand what the reemergence of measles might look like, Wisconsin Watch spoke with residents who contracted the disease decades ago as children, including some who still live with complications today. They described high fevers and days of bed-ridden isolation during the infections, as well as lasting damage to their bodies — like the hearing loss some live with now.

Health professionals across the state told Wisconsin Watch they’re preparing to recognize the signs of a disease they’ve rarely, if ever, treated — and to respond to potential outbreaks.

When nothing stopped measles

In the days when measles ran rampant, medical treatment was limited. Families largely cared for sick children at home, relying on home remedies and passed-down knowledge, or the occasional house call from a doctor.

Thompson remembers her days sick at home. Her mother applied calamine lotion to relieve itching around her rashes, and Thompson was required to stay in a dark room wearing sunglasses for fear that the disease would damage her eyes. The worst part, she recalled, was being packed in ice to manage her over 100-degree fever.

Other common treatments in decades past included isolating to prevent spreading the virus to others and spending days in bed until symptoms wore off. 

With no vaccine to block infections, some officials advised parents to have their children catch measles early — particularly for daughters, so they would be less likely to contract it later during a pregnancy. 

Newspaper accounts in the 1950s and 1960s described the phenomenon of “measles parties,” in which children were deliberately exposed to others infected with the virus.

Those also applied to German measles, or rubella, a milder virus linked to severe birth defects during pregnancy. 

Kathleen Cooper of Rhinelander remembers those parties. When she ultimately caught measles at age 6, she was confined to a darkened room and prevented from watching television due to fears that bright light might cause blindness — similar to what Thompson recalled.

Cooper was supposed to attend a birthday party that weekend. Instead, the party came to her.

“That’s how they treated it back then,” said Cooper, now 73. “If one kid in the neighborhood got the chickenpox or the measles, everybody went over to their house so the mothers could just get it over with, because it was just something that you had to get through.”

Lasting toll from measles

But measles parties did not protect people from the misery of the disease. Infections only spread. 

“I was ill and bedridden for weeks. When I was finally able to get up I was a skeleton. My pants couldn’t stay up and my clothes hung on me,” Door County resident Pam Goodlet recalled of a measles bout in 1963 as a 13-year-old. 

Delirious with fever and unable to eat or drink water, Goodlet stayed hydrated by sucking on ice cubes. She recalled being visited by a doctor just once and was never taken to a hospital or clinic.

Goodlet ultimately recovered without long-term health consequences, but many others weren’t so lucky.

Of the estimated 3 to 4 million Americans infected each year before vaccinations, an estimated 48,000 were hospitalized and 400 to 500 died, according to the U.S. Centers for Disease Control and Prevention. 

In 1967, a column published in the Waukesha Daily Freeman described the stories of children whose lives were permanently altered by the disease. 

They included a Watertown toddler who was hospitalized and diagnosed with a cognitive impairment after an infection that occurred one year before vaccines became widely available in 1963. 

“Too late for Valerie,” the toddler’s mother reportedly lamented.

Another child was described as healthy until developing encephalitis — a dangerous inflammation of the brain — at the age of 2 due to measles. The condition left her mentally impaired and also deaf, the newspaper reported. An estimated 1,000 children annually suffered encephalitis from measles in the pre-vaccination era.

Leslie Fedorchuk of Milwaukee still lives with the effects of her measles infection.

She was about 6 years old when she realized something wasn’t right with her hearing. As her mother’s friend kept dialing her home’s wall-mounted phone, Fedorchuk, perched on a chair to reach it, would answer, hear nothing and hang up.

It took her mother picking up to realize her friend was speaking each time, but Fedorchuk couldn’t hear from her right ear. The episode happened shortly after Fedorchuk contracted measles and mumps simultaneously.

“I’m in my 70s, and I’ve lived with it my whole life,” Fedorchuk said. “When I hear people say, ‘Oh, nothing can happen if you don’t get a vaccination,’ I think, ‘Oh, yeah, something can definitely happen.’”

Peggy Haas, 69, a registered nurse in Waukesha County, became a firm believer in vaccines after witnessing the damage measles could inflict.

While finishing her master’s degree at Marquette University in 1987, she taught undergraduate students in the pediatrics ward at St. Joseph Hospital in Milwaukee. One day she assigned a student to care for a woman in her 20s who, due to measles complications, had the developmental capacity of an infant.

“She couldn’t talk, she couldn’t feed herself, she couldn’t even walk,” Haas said. “That was the first time I’d seen anybody who had failed to vaccinate their child and what it could do.”

Potential measles complications run the gamut from ear infections and diarrhea to more serious issues like pneumonia and encephalitis. Such brain swelling can cause permanent tissue damage, leading to hearing loss or other serious neurological complications.

Some potential effects aren’t immediately visible. Measles can disrupt the part of the immune system that remembers previous infections, a phenomenon known as immunity amnesia. That leaves people more vulnerable to future viruses for two to three years after a measles infection.

“For example, if you’ve been immunized for polio, and then you get a measles infection, the immunity you had to polio could be wiped out or reduced,” said Malia Jones, a University of Wisconsin-Madison assistant professor in the Department of Community and Environmental Sociology. “You wouldn’t even know that you’re susceptible to some of this stuff.”

The mortality rate for measles is just 1 in 1,000, but the risk of a weakened immune system makes the toll of measles higher, Jones noted. And while medical care has dramatically improved since the 1960s, no specific treatment exists for measles today.

“We just offer supportive care — in the hospital for those who become very sick — and hope for the best,” Jones said.

Vaccine was ‘a turning point in public health’ 

By the 1960s, vaccine breakthroughs showed that cases of measles were preventable. 

The first measles vaccine was licensed in the U.S. in 1963. By 1971 it was combined with vaccines for mumps and rubella, paving the way for the MMR vaccine used today. 

Early uptake was limited, and in 1983, the MMR vaccine was only routinely recommended for 1-year-olds.

But it soon became clear that a single dose fell short of offering full long-term protection. A second dose was added in 1989 to the routine schedule for children before starting school. Taking two vaccine doses is about 97% effective at preventing measles, the CDC says, compared to 93% for one dose.

The two-dose regimen initiated more regular contact between young children and health care providers. That led to more early developmental checks, including hearing, vision and behavioral assessments now standard in pediatric care. It also paved the way for childhood vaccination schedules to prevent other diseases, said Dr. Jim Conway, a UW-Madison professor in the Divisions of Infectious Diseases and Global Pediatrics.

“The MMR vaccine was a really major turning point in public health,” he said.

By the early 2000s, measles was declared eliminated in the U.S., meaning it wasn’t continuously spreading for a period longer than a year. 

How health officials are responding

But the virus is back, with the U.S. seeing more than four times as many infections in 2025 than in all of 2024. And it has now been detected in Wisconsin. 

In Oconto County, “all of the cases were exposed to a common source during out-of-state travel,” the state health department said in a statement Saturday.

“DHS, in coordination with the Oconto County Public Health, is working to identify and notify people who may have been exposed to the measles virus,” the statement said. “At this time no public points of exposure have been identified and the risk to the community remains low.”  

Wisconsin is vulnerable to an outbreak due to its relatively low childhood vaccination rates. It is one of just 15 states that allow vaccine exemptions for medical, religious and personal belief reasons. No Wisconsin county comes close to reaching the vaccination rate of 95% that is considered the benchmark for herd immunity protection. 

Public health officials are bracing themselves to respond.

Jennifer Weitzel, director for public health in Sauk County, said her department began closely monitoring measles this year after a Texas outbreak resulted in hundreds of infections and killed two unvaccinated school children. The department is being attentive as popular destinations like Wisconsin Dells and Devil’s Lake draw out-of-state visitors this summer. Just 70% of Sauk County’s kindergarten-aged children received two doses of the vaccine in 2024, down from 76% in 2019. 

The health department is working with providers and doctors to communicate the important protections vaccines bring. 

“I think that’s part of the challenge … no one sees these diseases anymore, so we forget just how effective vaccines have been and how awful these diseases really are,” Weitzel said.

Her colleagues coordinate tabletop exercises with other health departments, including those in Richland County and the Ho-Chunk Nation, practicing communication and response protocols in worst-case scenarios.

Health officials say they are trying to build trust in an era of misinformation surrounding viruses and vaccines. 

“Public health also took a big hit during COVID,” Weitzel said. “Folks are leery of government overreach, of recommendations, so we’re trying to build back that trust at a time where it’s critical, because measles is spreading, and we know that we could prevent it.”

But Holly Neri, a public health nurse in Door County, sees some positives from the COVID-19 pandemic: It prompted public health professionals to better prepare for virus outbreaks.

Door County nurses have sought to make sure patients are up to date on vaccinations. A state immunization grant for purchasing vaccines has helped, Neri said. The goal is for at least 78% of Door County children to be current on their vaccines by age 2, including MMR.

Their department is sharing information with local medical providers about identifying and responding to measles. 

Some groups, such as pregnant women and very young infants, cannot be safely vaccinated. That makes it particularly important for others to do so — aiming to get as close to herd immunity as possible, said Rebecca Wold, public health supervisor for the Oneida County Health Department. 

“If you’re not sure of your immunity or vaccination status, you don’t have any record of having a measles vaccine or having had measles as a child, it is safe to get a measles vaccine, and we would recommend it,” Wold said.

Before the 1960s, hundreds of thousands of Americans faced measles infections each year. The advent of vaccination eliminated the disease in the United States by 2000. But outbreaks have returned to some U.S. communities as trust in vaccines wanes in many communities.

More than 1,300 measles cases have been confirmed this year across 41 states, the latest being Wisconsin. That’s after the state Department of Health Services on Saturday announced it confirmed nine measles infections in Oconto County — the first in Wisconsin this year. 

Each Oconto County infection involved exposure to a “common source during out-of-state travel,” the state health department said in a statement. 

“DHS, in coordination with the Oconto County Public Health, is working to identify and notify people who may have been exposed to the measles virus,” the statement said. “At this time no public points of exposure have been identified and the risk to the community remains low.”  

What should Wisconsin families know about measles? 

Wisconsin Watch spoke with two University of Wisconsin-Madison experts: Dr. Jim Conway, a professor in the Divisions of Infectious Diseases and Global Pediatrics; and Malia Jones, an assistant professor in the Department of Community and Environmental Health.

We gathered additional information from officials at multiple rural public health departments across Wisconsin and reports from the U.S. Centers for Disease Control and Prevention.

Below are some takeaways. 

When and where am I most susceptible to measles?

That depends on individual health and vaccination status. Very young people (especially infants too young to be vaccinated), older adults and people with compromised immune systems face higher risks for contracting measles and developing severe complications.

Measles tends to spread more easily in crowded urban environments and during travel. However, it can spread anywhere, as evidenced by recent rural outbreaks, including those in Texas, where hundreds of infections have been confirmed and two school children have died. All it really takes is exposure to an infected person. Measles is one of the most highly contagious known diseases. It can remain infectious in the air or on surfaces even after an infected person leaves the area.

To put it in perspective, measles is often reported to have an R nought value — the number used to describe contagiousness — between 12 and 18. That means if one person with measles walked into a room of vulnerable people, odds are they would infect 12 to 18 others in the room. 

What should I do if I start having measles symptoms?

Measles often starts with general cold-like symptoms such as fever, cough, runny nose and watery eyes, making it hard to immediately recognize. The rash typically appears a few days after infection — and after a contagious person may have exposed others. 

If you think you might have measles or have been exposed to it, contact your local health department or healthcare provider immediately — especially if you’re unvaccinated or traveled to an area where cases were reported.  Suspected cases can be reported to local health departments even before confirmation, allowing officials to respond more quickly. Experts recommend staying home while waiting for test results to avoid spreading the virus.

What are the risks of measles?

While some think of measles as a mild childhood illness that everyone used to get, it can be dangerous. The disease can lead to a range of complications, from ear infections and diarrhea to more severe pneumonia or brain-swelling encephalitis. Such brain inflammation can affect multiple parts of the body and even cause permanent damage, especially to the brain and hearing. 

Meanwhile, a  rare but fatal long-term brain disease called subacute sclerosing panencephalitis can develop years after the initial infection. 

Some people infected by measles may experience neurological issues or nerve damage later in life.

One lesser-known risk factor: Measles can disrupt the part of the immune system that remembers previous infections, a phenomenon known as immunity amnesia. That leaves people more vulnerable to future viruses for two to three years after a measles infection.

In higher-income countries measles kills 1 to 3 of every 1,000 people infected, 10% to 20% of infections requiring hospitalization — often due to pneumonia, dehydration or severe diarrhea. Encephalitis occurs in about 1 in 1,000 cases, and pneumonia occurs in about 5% of infections. Children who are malnourished or have limited access to medical care face significantly greater risks. 

U.S. health officials have confirmed three measles-related deaths this year. 

What if I’m unsure whether I’ve had measles or the vaccine?

If you were born before 1957, you’re generally considered immune to measles because the virus was so widespread during the pre-vaccine era. Many adults born in the 1960s and 1970s may assume they’re protected when, in fact, they were never fully vaccinated, or even vaccinated at all. A second dose of the measles, mumps and rubella (MMR) vaccine wasn’t added to routine childhood immunization schedules until 1989, so many adults missed one or both recommended doses. 

The bottom-line is if there’s any uncertainty around your vaccination status, it’s safe to get vaccinated again. There’s no harm in receiving an additional dose of the MMR vaccine. In fact, an extra dose is both safe and more practical — quicker and more cost-effective than getting a blood test to check your immunity.

“More is better,” Conway said. “This is not one of the vaccines that has particularly tough side effects.”

Staying up to date not only protects you from serious illness but also helps safeguard others in your community who may be more vulnerable to complications from measles.

What can I do to protect myself and others?

Vaccination is your best defense. The MMR vaccine is the most effective way to protect yourself and those around you from measles. Make sure you’ve received both recommended doses, and stay informed about outbreaks in your community, especially if you’re traveling or belong to a vulnerable group.
