Abstract
HIV/AIDS emerged in the 1980s and created an urgent need for detection tests. Laboratory tests to detect HIV antibodies in blood samples were developed, followed by rapid tests in the 1990s. In the 2000s, HIV self-testing kits were introduced, improving accuracy and ease of use. Self-testing has become crucial in the fight against HIV. By 2030, the United Nations Programme on HIV/AIDS (UNAIDS) sets goals for detection and treatment. Despite progress, challenges such as stigma and education persist. In Latin America, national self-testing programs are being implemented, such as in Chile, Brazil, and Colombia. In Mexico, the approval of self-tests in 2024 represents a significant advancement. Self-tests are expected to be widely used to detect the disease early, ensuring privacy and reducing stigma and discrimination. They will also be used for research in vulnerable groups and to refer patients to pre-exposure prophylaxis (PrEP) services. With these actions, the aim is to achieve the goals set by UNAIDS and improve public health in the fight against HIV.
