World Health Organization (WHO) is a specialized agency of the United Nations responsible for international public health. It is part of the U.N. Sustainable Development Group.
WHO is building a better, healthier future for people all over the world. Working with 194 Member States, across six regions, and from more than 150 offices, WHO staff are united in a shared commitment to achieve better health for everyone, everywhere.
Together we strive to combat diseases – communicable diseases like influenza and HIV, and noncommunicable diseases like cancer and heart disease.
WHO help mothers and children survive and thrive so they can look forward to a healthy old age. We ensure 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 we now celebrate every year as World Health Day.
We are now more than 7000 people working in 150 country offices, in six regional offices and at our headquarters in Geneva, Switzerland.
Our primary role is to direct and coordinate international health within the United Nations system.
Our main areas of work are health systems; health through the life-course; noncommunicable and communicable diseases; preparedness, surveillance and response; and corporate services.
