We are constructing a more prosperous and healthy future for people everywhere. The personnel of WHO is committed to promoting better health for everyone, everywhere, and work with 194 Member States, across six regions, and from more than 150 locations. Together, we work to fight diseases like cancer and heart disease as well as non-communicable conditions like the flu and HIV. We support moms and children so that they can have healthy adulthood. We guarantee the security of the water people drink, the food they eat, the air they breathe, and the necessary medications and immunizations.
