How do the HIV/Aids pandemic statistics vary around the world?

HIV (human immunodeficiency virus) causes AIDS (Autoimmune deficiency syndrome) and reduces the ability of body to fight infection.

HIV was first found in 1959 in a man from Democratic Republic of the Congo and then announced as a world pandemic by WHO.

Approximately 37.9 million people were infected with HIV globally in 2018 but the pandemic statistics vary around the world. Sub-Saharan Africa was most infected region from HIV in 2018 where 61% population was infected from HIV/AIDS. In South & South-East Asia, about 12% of all people infected with HIV in 2010.

Now WHO announced HIV as 'global epidemic".
