WORLD HEALTH ORGANIZATION aims to build a better, healthier future for people all over the world. 194 WHO Member States work across six regions of the world in 150 offices, united in a shared commitment to achieve better health for everyone, everywhere. Together they strive to combat communicable and non communicable diseases like influenza, HIV, cancer and heart disease. WHO helps mothers and children survive and thrive so they can look forward to a healthy old age. They ensure the safety of the air people breathe, the food they eat, the water they drink – and the medicines and vaccines they need.
