Antibiotics revolutionized medicine, but their effectiveness is threatened by resistance. This new page presents global data and research on antibiotics and antibiotic resistance.<br><br><a href="https://ourworldindata.org/antibiotics" target="_blank"><img src="https://ourworldindata.org/cdn-cgi/imagedelivery/qLq-8BTgXU8yG0N6HnOy8g/0983df2b-3d7f-416f-71be-f4ad93a8a100/w=1350"/></a>

Many antibiotics were developed during the “Golden Age of Antibiotics”. How did it happen, why has antibiotic development slowed down since then, and what can we do to reignite it?<br><br><a href="https://ourworldindata.org/golden-age-antibiotics" target="_blank"><img src="https://ourworldindata.org/cdn-cgi/imagedelivery/qLq-8BTgXU8yG0N6HnOy8g/7b3bf2c1-8af6-4e65-2e92-d5e4d781d800/w=1350"/></a>

To use antibiotics more effectively, it’s important to know how different antibiotics work and how antibiotic resistance can evolve and spread.<br><br><a href="https://ourworldindata.org/how-do-antibiotics-work" target="_blank"><img src="https://ourworldindata.org/cdn-cgi/imagedelivery/qLq-8BTgXU8yG0N6HnOy8g/eebf1100-356d-4d5a-de9a-458070451700/w=1350"/></a>

Long-distance moves are becoming more common, but they remain the exception. For most, international migration still means crossing a nearby border, not an ocean.<br><br><a href="https://ourworldindata.org/international-migrants-dont-move-far" target="_blank"><img src="https://ourworldindata.org/cdn-cgi/imagedelivery/qLq-8BTgXU8yG0N6HnOy8g/52b29637-7d81-4492-8e8f-2e46b03b7c00/w=1350"/></a>

Many countries refuse to share their data, which is a risk for antimicrobial resistance.<br><br><a href="https://ourworldindata.org/antibiotics-livestock-data" target="_blank"><img src="https://ourworldindata.org/cdn-cgi/imagedelivery/qLq-8BTgXU8yG0N6HnOy8g/f76ef941-7b32-4c9f-4fcf-c6a07067ff00/w=1350"/></a>

Overuse is a risk for antibiotic resistance, but there are ways to reduce it.<br><br><a href="https://ourworldindata.org/antibiotics-livestock" target="_blank"><img src="https://ourworldindata.org/cdn-cgi/imagedelivery/qLq-8BTgXU8yG0N6HnOy8g/f40ec941-5824-4d88-c91d-6012bd888e00/w=1350"/></a>
