Answer 1

AIDS is caused by the Human Immunodeficiency Virus (HIV), which is transmitted through sexual contact, blood transfusion, and from mother to child. HIV damages the immune system and can lead to AIDS, the most severe stage of the infection.

Step-by-step explanation:

Acquired Immunodeficiency Syndrome, or AIDS, is caused by the Human Immunodeficiency Virus (HIV). This virus attacks the immune system, significantly reducing its ability to fight off infections and diseases. HIV is transmitted through several means, including sexual contact, blood transfusions, sharing of needles, and from mother to child during birth or breastfeeding. Once a person contracts HIV, it can eventually lead to AIDS, which is the final and most severe phase of the infection.

There are two main variants of HIV: HIV-1, which is widespread worldwide, and HIV-2, which is more localized to West Africa. Currently, sub-Saharan Africa is the region most affected by HIV. With the advent of antiretroviral treatment, HIV has become a manageable chronic condition, rather than the fatal disease it once was in its early discovery in the 1980s.
