How does HIV multiply in the human body?
HIV multiplies in the human body by invading cells and using the cell’s own machinery to make copies of itself. Specifically, HIV attaches to the CD4+ T cells, also called T helper cells, and some other cell types like macrophages, and then enters the cell. Once inside, it uses the cell’s genetic material to make new copies of itself. These copies are then released to infect other cells. In the process, the infected cells are destroyed, leading to a gradual decline in the number of CD4+ T cells and weakening the body’s ability to fight off infections.
