The World Health Organization is the directing and coordinating body for international health work within the UN system.

WHO is building a better, healthier future for people all over the world. Together all members strive to combat diseases – communicable diseases like influenza and HIV, and noncommunicable diseases like cancer and heart disease. WHO helps mothers and children survive and thrive so they can look forward to a healthy old age, it ensures the safety of the air people breathe, the food they eat, the water they drink – and the medicines and vaccines they need.
