The Long and Challenging Quest to Understand HIV and AIDS

TLDRHIV/AIDS, a disease that has infected 70 million people and caused 35 million deaths, took decades to understand and treat. HIV is a retrovirus that infects immune cells known as CD4 T cells. It is transmitted through bodily fluids but not saliva. The initial symptoms are similar to the flu. AIDS occurs when the virus kills off too many T cells, leaving the body vulnerable to infections. HIV likely originated from chimpanzee SIV and jumped to humans through hunting bushmeat. The epidemic spread globally through various routes.
