HIV Transmission Routes Explained

HIV (Human Immunodeficiency Virus) is transmitted through specific bodily fluids from an infected person. Understanding these routes is crucial for prevention.

Primary Transmission Methods

• Sexual Contact: HIV can be transmitted during unprotected sexual intercourse (vaginal, anal, or oral) with an infected person. This is the most common route worldwide.
• Blood Transfusion: Transmission can occur if an infected person's blood or blood products are transfused into an uninfected person. Screening of blood donations significantly reduces this risk in most countries.
• Sharing Needles: Sharing contaminated needles, syringes, or other drug-injection equipment can transmit HIV.
• Mother-to-Child: HIV can be transmitted from an infected mother to her child during pregnancy, childbirth, or breastfeeding.

Non-Transmission Methods

Certain activities do not transmit HIV:

• Kissing and Hugging: Casual contact like kissing (even deep kissing) and hugging does not transmit HIV as the virus is not present in saliva in sufficient quantities or transmitted through skin contact.
• Eating Together: Sharing utensils or food does not transmit HIV.
• Droplet and Airborne Transmission: HIV is not spread through the air (like a cold or flu) or via respiratory droplets.

Based on the primary transmission methods, options A (Sexual Contact) and B (Blood Transfusion) are correct ways HIV can be transmitted.
