Global HIV Prevalence

Featured

As part of the new Sustainable Development Goal 3 which aims to “ensure healthy lives and promote well-being for all at all ages” the UN concludes, that “the incidence of [HIV] has declined globally since 2000. […] The incidence of HIV was highest in sub-Saharan Africa, with 1.5 new cases per 1,000 uninfected people.” Despite longer term positive trends, a recent UNAIDS report stated that “new HIV infections among adults have stalled, failing to decline for at least five years.” This shows that HIV remains a global challenge that needs continuing prevention efforts and ongoing awareness and education. In 2015 it was estimated that globally 34.0 to 39.8 million people are living with HIV.
