Epidemiology of HIV infection and AIDS

Background: The expansion of antiretroviral therapy (ART) has resulted in a reduction in numbers of new human immunodeficiency virus (HIV) infections and acquired immunodeficiency syndrome (AIDS)-related deaths worldwide, except in some regions. As people with HIV live long and healthy lives, their health issues are also changing. In this review, we briefly summarize the global HIV epidemic and examine the changing trends in the epidemiology of HIV in Korea. Current Concepts: Since 2013, more than 1,000 new infections have been reported in Korea every year, and after reaching its peak at 1,223 in 2019, approximately 1,000 were reported each year during the coronavirus disease 2019 pandemic. Most newly infected people were men, and the proportion of young people aged 20 to 40 years, men who have sex with men, and foreigners has been steadily increasing. AIDS was the most common cause of death, and cancer, chronic diseases, and suicide were also important causes of death in Korea. Discussion and Conclusion: Achieving sustained ART and viral suppression is approaching the UNAIDS 95-9595 targets in Korea, but additional research and efforts are required to reduce late presentation and scale-up of HIV diagnosis. Targeted and coordinated prevention programs to prevent HIV among people from key populations are also needed. Additionally, supportive services for older people with HIV, including cancer screening and chronic disease management, and multifaceted efforts to reduce stigma and discrimination against people with HIV are needed in Korea.
