What is the difference between HIV and AIDS?
Explaining the two terms, Dr. Rohan Sequeira, Consultant General Medicine, Jaslok Hospital & Research Centre, said, "As the name suggests, HIV (human immunodeficiency virus) essentially targets the auto immunity of the person. There are different kinds of cells in the body called T cells (also called T lymphocytes), B cells, and memory cells, among others. HIV virus destroys those cells and leaves the body with no defence mechanism."
HIV is the virus which causes the infection and AIDS is the last stage of the HIV infection where the immune system of the body is completely knocked out, added Dr Sequeira.
