Total number of new HIV infections worldwide

Human immunodeficiency virus (HIV) is a condition that slowly destroys or impairs the body’s immune system. It is a retrovirus that slowly progresses through the various stages of the disease. As HIV reproduces, it mutates its structure which makes it difficult to treat through drug therapy. Almost 38 million people were living with HIV worldwide as of 2018 with some 23.3 million people accessing ART treatment around the world. There are various types of ways to treat HIV. Antiviral treatment has been on the decline as combination therapy such as fixed-dose combinations become more popular.

New HIV infections worldwide have been on the decline since 2000 from 3.2 million new infections to less than two million new infections in 2018. Many new infections occur in developing countries, especially those in low- and middle-income countries in Sub-Saharan Africa. Many of these individuals have no access to drugs or treatment that can make living with HIV more manageable. Children are also susceptible to infection, often from HIV-positive mothers during pregnancy, childbirth, or breastfeeding. There are approximately 1.7 million children living with HIV globally.
