What we do

WHO leads global efforts to expand universal health coverage. We direct and coordinate the world’s response to health emergencies. And we promote healthier lives – from pregnancy care through old age. Our Triple Billion targets outline an ambitious plan for the world to achieve good health for all using science-based policies and programs. 

Who we are

Founded in 1948, WHO is the United Nations agency that connects nations, partners, and people to promote health, keep the world safe, and serve the vulnerable – so everyone, everywhere, can attain the highest level of health. 

Our work

We put science to work to build a healthier, safer world

The World Health Organization leads and champions global efforts to achieve better health for all. By connecting countries, people, and partners, we strive to give everyone, everywhere, an equal chance at a safe and healthy life.

From emerging epidemics such as COVID-19 and Zika to the persistent threat of infectious diseases, including HIV, malaria, and tuberculosis, and chronic diseases such as diabetes, heart disease, and cancer, we bring together 194 countries and work on the frontlines in 150+ locations to confront the most significant health challenges of our time and measurably advance the well-being of the world’s people.
