Question

how aids is caused

Answer 1

AIDS or Acquired Immuno Deficiency Syndrome is a viral disease, caused by the Human Immunodeficiency Virus (HIV).

AIDS is transmitted by following means:

• AIDS can be transmitted by sharing contaminated needles while injecting drugs.
• AIDS can be transmitted by having sexual contact with an infected person.
• AIDS can also be transmitted from an infected mother to the child through pregnancy or breast feeding.
• Transfusion of infected blood.

After HIV virus gets into the body, it kills or damages cells of the body's immune system like WBCs. The virus progressively destroys the body's ability to fight infections and certain cancers. The immune system become so weak that body is not able to fight minute infections also. HIV positive individuals are at serious risk of death as a result of their weakened immune systems.
