The World Health Organization (WHO), first established in 1948, is a global organization dedicated to ensuring the best quality healthcare for everyone worldwide. WHO is part of the United Nations Development Group and has on-the-ground presence in more than 150 countries. This presence allows them to work alongside local governments and partners to establish a local strategy to improve all health-related issues. WHO focuses specifically on disease, sexual and reproductive health, development, aging, food security and healthy eating, occupational health, and substance abuse.
