Diseases don’t stop at borders, which is why the work of the World Health Organization (@WHO) to protect global health matters to Americans and to people everywhere. From the eradication of #smallpox in 1979 to its work today strengthening global health security, preparing for and responding to pandemics, addressing #health threats, and providing medical services in humanitarian emergencies, WHO works to keep families healthy. On #WorldHealthDay, we are raising awareness of WHO and its lifesaving work. #WorldHealthDay #FridayFacts #USUN #SocialGood Photo: WHO/A. Clements-Hunt
