The annual World Health Day is celebrated again at the beginning of April. Introduced in 1948 by the World health Organization (WHO) to commemorate its founding, it has been used ever since to draw attention to a specific health issue. Last year the focus was on supporting nurses and midwives. Throughout the day and beyond various activities are intended to help attract worldwide attention and encourage people to deal more intensively with the topic in a national context. The theme for the year 2021 will be published on the 7th of April 2021.
