The World Health Organization (WHO) was established with the objective of improving international public health. The first of its kind, this UN organisation raises awareness about various epidemics, diseases, and disorders while working towards their prevention. It also emphasises the need for proper sanitation and health practices to prevent proliferation of diseases. WHO has been an instrumental organisation in improving general well-being; successfully combating crippling diseases like Polio, Ebola, Smallpox, and edging ahead in the ongoing battle against HIV-AIDS. Dealing with aspects of healthcare, research and cross-border aid, WHO’s initiatives are unique and have proven to be a boon to the world.
