Question

Throw light on the three causes of AIDS.

Hint:

It is crucial to be precise: AIDS is the syndrome, while HIV is the virus that causes it. The 'causes' of AIDS are the modes of transmission of HIV.

Answer 1

AIDS (Acquired Immunodeficiency Syndrome) is a chronic, potentially life-threatening condition caused by the Human Immunodeficiency Virus (HIV). HIV attacks the body's immune system, making it vulnerable to other infections. The virus is transmitted through specific bodily fluids. The three main causes or modes of transmission are:

Unprotected Sexual Contact: This is the most common mode of transmission. The virus can be passed from an infected person to their sexual partner (vaginal, anal, or oral) through semen, vaginal fluids, and rectal fluids.

Transmission Through Infected Blood: HIV can be transmitted through contact with infected blood. This commonly occurs through:
Sharing of needles, syringes, or other drug injection equipment by intravenous drug users.

Unsafe blood transfusions or organ transplants using unscreened blood/organs.

Mother-to-Child Transmission (Perinatal Transmission): An HIV-infected mother can pass the virus to her baby during pregnancy, childbirth, or through breastfeeding.
