The immune system is attacked by the human immunodeficiency virus, or HIV, in particular by CD4 cells (or T cells). Body fluids like blood, semen, vaginal fluids, anal fluids, and breast milk can all spread the virus.
HIV has historically been transmitted most frequently during unprotected sex when using shared needles for drug use, and during childbirth.
The most severe type of HIV infection, acquired immunodeficiency syndrome, or AIDS, can develop over time when HIV destroys so many CD4 cells that the body is unable to fight against infections and diseases. Cancer and potentially fatal illnesses like pneumonia are very likely to affect someone with AIDS.
A person with HIV who seeks treatment early can live almost as long as someone without the virus, despite the fact that there is no cure for either HIV or AIDS. The transmission of HIV was effectively stopped by an anti-viral medication, according to a study published in the medical journal Lancet in 2019.
When Was HIV First Identified In The United States?
Despite the disease’s origins being decades earlier, the HIV and AIDS outbreak that swept the United States and the rest of the world in the 1980s and early 1990s was caused by this. In 1981, doctors in Los Angeles, New York City, and San Francisco found clusters of Kaposi’s sarcoma and pneumocystis pneumonia in homosexual men.
In the United States, there are currently over 1.2 million people living with HIV, and more than 35,000 new infections occur a year. In the United States, HIV-related illnesses have claimed the lives of more than 700,000 people.
