HIV/AIDS has been a public health concern for Latin America due to a remaining prevalence of the disease. In 2018 an estimated 2.2 million people had HIV in Latin America and the Caribbean, making the HIV prevalence rate approximately 0.4% in Latin America. Some demographic groups in Latin America have higher prevalence rates for HIV/ AIDS including men who have sex with men having a prevalence rate of 10.6%, and transgender women having one of the highest rates within the population with a prevalence rate of 17.7%. Female sex workers and drug users also have higher prevalence for the disease than the general population (4.9% and 1%-49.7% respectively). One aspect that has contributed to the higher prevalence of HIV/AIDS in LGBT+ groups in Latin America is the concept of homophobia. Homophobia in Latin America has historically affected HIV service provision through under reported data and less priority through government programs. Antiretroviral treatment coverage has been high, with AIDS related deaths decreasing between 2007 and 2017 by 12%, although the rate of new infections has not seen a large decrease. The cost of antiretroviral medicines remain a barrier for some in Latin America, as well as country wide shortages of medicines and condoms. In 2017 77% of Latin Americans with HIV were aware of their HIV status. The prevention of HIV/AIDS in Latin America among groups with a higher prevalence such as men who have sex with men and transgender women, has been aided with educational outreach, condom distribution, and LGBT+ friendly clinics. Other main prevention methods include condom availability, education and outreach, HIV awareness, and mother-to-child transmission prevention. Origin and epidemiology of HIV/AIDS in Latin America The first documented reporting of what would come to be known as HIV/AIDS happened in June 1981. In September 1982, AIDS is given its name and a case definition for the very first time. Specific details on the origin of HIV/AIDS in Latin America are lacking, but in 1983, the first known HIV cases in Latin America were confirmed in Mexico and Haiti in the form of the HIV-1. Blood screening in Mexico was scare in the early 1990s, which contributed to 63% of female AIDS cases stemming from blood transfusions. Currently, the prevalence rate of HIV/AIDS in Latin America is highest in Belize (2%), Honduras (1.9%), Panama (1.54%) and Guatemala (1.4%). Since 2000, the prevalence of HIV/AIDS in the Caribbean has been highest
