World Health Day is celebrated every year on the founding day of the World Health Organization. Established in 1950 this event has a theme each year to draw attention to a current world health issue. The WHO puts together regional, local, and international events on this day related to that theme. Local governments also tend to jump on this band-wagon, after all, global health means everyone! On this day you may take some extra steps to care for your health, consider getting a gym membership (and going!), starting a diet, or starting multi-vitamins!
The World Health Organization is an agency of the United Nations that focuses on the public health of the world at large. The WHO has a constitution that countries involved in the United Nations had an opportunity to sign, and unanimously did, agreeing to the tenets laid out within to promote the general health of the globe. Through its efforts we have seen the eradication of small pox, and its focus then turned to communicable diseases, with a particular focus on tuberculosis and HIV/AIDS.
The World Health Organization has been involved in mobilizing many health efforts the world over. Describing what medicines are essential for public health, and which diseases to give a particular focus to. The movement to eradicate smallpox started in 1958, initiated by pressure from Viktor Zhdanov, the Deputy Minister of Health for the then USSR. In 1979, the WHO declared that smallpox had in fact been eradicated, making it the first disease in history to be eliminated by the dedicated efforts of humans.
