HIV- Human Immunodeficiency Virus is a deadly virus which reproduces itself inside the body of the host. This virus damages the immune system of the host completely. The body of the infected person is no longer able to fight infections and other diseases. The damaged immune system makes the human body more prone to many diseases. HIV attacks the immune system by destroying CD4 positive (CD4+) T cells, a type of white blood cell which is required to fight infection. The destruction of these cells makes the infected person more vulnerable to infections, diseases, and other complications.
AIDS- Acquired Immune Deficiency Syndrome is a disease which develops in a person suffering from HIV. The advanced stage of HIV leads to the development of AIDS. It is the final stage of HIV infection when the infected person has one or more opportunistic infections, such as pneumonia or tuberculosis, and has a dangerously low number of CD4+ T cells (less than 200 cells per cubic millimeter of blood).
