The International Day of Epidemic Preparedness is observed on December 27 each year. The United Nations created it in 2020, during the COVID-19 pandemic, to highlight the importance of preventing, preparing for and responding to disease outbreaks. The date marks the birthday of Louis Pasteur, the French scientist whose work on germs and vaccines transformed medicine.
History of International Day of Epidemic Preparedness
Epidemics have shaped human history, from the Black Death in the 1300s to the 1918 influenza pandemic, which killed tens of millions of people worldwide. Advances in science, such as germ theory, vaccines and antibiotics, dramatically improved the world's ability to fight infectious diseases.
Louis Pasteur, born on December 27, 1822, helped prove that germs cause disease and developed vaccines for rabies and anthrax. His work, along with that of other scientists, laid the foundation for modern public health.
In December 2020, the UN General Assembly designated December 27 as the International Day of Epidemic Preparedness, recognizing that the COVID-19 pandemic had shown the need for stronger preparedness, international cooperation and investment in health systems.
Why International Day of Epidemic Preparedness Matters
Preparedness can save lives by helping communities respond quickly to outbreaks.
The day highlights the importance of strong health systems, research, vaccines and accurate information.
It also encourages individuals to take simple steps, such as staying up to date on vaccines, practicing good hygiene and keeping basic supplies at home.
History shows that preparedness pays off. Countries and communities that invest in disease surveillance, laboratory capacity and trusted communication can detect outbreaks earlier and respond faster. Simple household steps, such as keeping a thermometer and basic medicines on hand, also help families cope when illness strikes.
How to Celebrate International Day of Epidemic Preparedness
- Check your vaccines: talk to a health care provider about recommended vaccines.
- Practice hygiene: wash hands and cover coughs and sneezes.
- Prepare a kit: keep basic medicines and supplies at home.
- Follow trusted sources: rely on the CDC, WHO and local health departments.
- Learn history: read about Louis Pasteur and past epidemics.
Celebrating at Work, School and Home
At work, review sick-leave policies, remote-work plans and hygiene supplies. In classrooms, students can learn about germs with simple experiments, study Louis Pasteur, or create handwashing posters. At home, families can update emergency kits, review handwashing, and talk calmly with children about how scientists and doctors help keep people healthy.
