World Health Day 2023

World Health Day 2023

April 7, 2023

World Health Day is celebrated every year on April, 7. In 2023, this date also marks the 75th anniversary of the World Health Organization (WHO). This is an opportunity to look back at the history of the WHO and advances in public health, and to talk about the contribution of our medical writing agency to some of these programs.

History of the World Health Organization (WHO)

The creation of an international health organization was proposed by the representatives of Brazil and China in April 1945, during the conference to set up the United Nations (UN) that was held in San Francisco. The goal was to “promote health, keep the world safe and serve the vulnerable – so everyone, everywhere can attain the highest level of health and well-being.”

In the begining, the WHO was governed by 61 Member States but this number has now grown to 194 members. More than 7,000 people including doctors, epidemiologists, scientists, and managers work for the WHO. The headquarters are located in Geneva, Switzerland.

Roles of the World Health Organization (WHO)

The WHO definition of health, established in 1946 and still in force to this day, is as follows: “Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.

The role of the WHO is to lead and coordinate global health within the United Nations system. The WHO helps countries achieve their health goals by supporting their health policies. With the goal of “improving health for everyone, everywhere”, the WHO ensures “the safety of the air people breathe, the food they eat, the water they drink – and the medicines and vaccines they need”.

World Health Day 2023

Every year, World Health Day is celebrated on April, 7. This date corresponds to the anniversary of the entry into force of the WHO Constitution in 1948. In 2023, the WHO celebrates “75 years of improving public health“.
