[88] HIV is a member of the genus Lentivirus, [89] part of the family Retroviridae. [90] Lentiviruses share many morphological and biological characteristics.
HIV tests have a high accuracy and the tests come in the form of antibody tests, antigen/antibody tests, and NATS (nucleic acid test). [32] There were approximately 38 million people across the globe with HIV/AIDS in 2019. Of these, 36.2 million were adults and 1.8 million were children under 15 years old. [33]

For example, HIV-infected people in the Midwestern United States are much more likely than people in New York City to develop histoplasmosis, which is caused by a fungus. A person in Africa is exposed to pathogens different from individuals in an American city. Children may be exposed to different infectious agents compared to adults. [87]
In immunocompromised patients, such as those with HIV, the infection becomes much more deadly, as without a consistent or strong enough immune response following bradyzoite formation, tachyzoites can escape from the cysts, facilitating further systemic infection and inflammation. [8]
A new long-acting preventive HIV drug could reach the world’s poorest countries by the end of 2025 or early 2026, a global health official told Reuters on Tuesday. The ambition is to start ...
