World Health Organisation (WHO)
Goal is to build a better, healthier future for people all over the world. Working through offices in more than 150 countries, WHO staff work side by side with governments and other partners to ensure the highest attainable level of health for all people.

Together WHO strives to combat diseases – infectious diseases like influenza and HIV and noncommunicable ones like cancer and heart disease. It help 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.

WHO began when our Constitution came into force on 7 April 1948 – a date WHO now celebrated every year as World Health Day. WHO has now more than 7000 people working in 150 country offices, in 6 regional offices and at our headquarters in Geneva.
