how is aids caused ?.
Answers
Answer:
AIDS/HIV is caused by a virus.
Explanation:
It can spread through sexual contact or blood, or from mother to child during pregnancy, childbirth or breast-feeding. HIV destroys CD4 T cells — white blood cells that play a large role in helping your body fight disease. The fewer CD4 T cells you have, the weaker your immune system becomes.

REQUIRED ANSWER-:
AIDS is caused by HIV. A person can’t get AIDS if they haven’t contracted HIV.
Healthy individuals have a CD4 count of 500 to 1,500 per cubic millimeter. Without treatment, HIV continues to multiply and destroy CD4 cells. If a person’s CD4 count falls below 200, they have AIDS.
Also, if someone with HIV develops an opportunistic infection associated with HIV, they can still be diagnosed with AIDS, even if their CD4 count is above 200.
