A healthy world
- The WHO was created out of the belief that "enjoyment of the highest attainable standard of health is one of the fundamental rights of every human being without distinction of race, religion, political belief, economic or social condition," according to its Constitution. This poster, illustrating a 1920's health campaign, reads: "Prevent Disease: Careless spitting, coughing, sneezing, spread influenza and tuberculosis."

Antiretroviral treatment
- HIV/AIDS is considered a pandemic and continues to be a major global public health issue, having claimed more than 32 million lives so far. There is no cure or vaccine; however, antiretroviral treatment can slow the course of the disease and may lead to a near-normal life expectancy. The WHO reported that approximately 37.9 million people were living with HIV at the end of 2018.

Argentina announces it will withdraw from the World Health Organization
Trump signed an executive order to pull out from the WHO in January
© <p>Getty Images</p>
It has been announced that Argentina will pull out of the World Health Organization (WHO), just weeks after the US confirmed that it would do the same.
Speaking at a news conference on February 5, presidential spokesperson Manuel Adorni confirmed that “President [Javier] Milei instructed [foreign minister] Gerardo Werthein to withdraw Argentina’s participation in the World Health Organization.” He went on to clarify that: “We Argentinians will not allow an international organization to intervene in our sovereignty, much less in our health.”
In January, President Donald Trump announced that the US would withdraw from the WHO, a decision that has prompted strong criticism from public health experts.
For over 75 years, the WHO has been promoting global health. They have kept the world safe from some of the most dangerous and infectious diseases on the planet and achieved the very highest standards of health for all.
Click through the following gallery for a brief overview of the WHO's greatest achievements since it was established in 1948.
