HIV AND AIDS.                            

HIV (Human immune-deficiency virus) is the pathogen that causes AIDS, a sexually transmitted disease. AIDS (Acquired Immune Deficiency Syndrome) is a disease in which the immune system of the human body is completely broken down, rendering the body unable to fight against pathogens that attack it. HIV belongs to a group of viruses referred to as retroviruses. They are capable of converting their RNA to DNA; they attack, infect, and destroy certain white blood cells called helper T cells or CD4 (lymphocytes).

MODE OF TRANSMISSION

1. Unprotected Sexual Intercourse – With an infected person (vaginal, anal, or oral sex).

2. Mother-to-Child Transmission – During pregnancy, childbirth, or breastfeeding.

3. Sharing of Contaminated Needles – Especially among drug users or in unsafe medical settings.

4. Transfusion of Infected Blood – Receiving unscreened or contaminated blood or blood products.

5. Sharing Sharp Objects – Like razors or blades with an infected person.                                                                                            SIGNS AND SYMPTOMS
