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 communicable 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 biggest health challenges of our time and measurably advance the well-being of the world’s people.
