HIV can be transmitted in several specific ways. Let me explain them clearly:

1. Sexual Contact:
- Unprotected sexual intercourse (vaginal, anal, or oral) with someone who has HIV
- The risk is higher with anal and vaginal sex

2. Blood Transmission:
- Sharing needles or syringes
- Blood transfusions (very rare in countries with blood screening)
- Accidental needle sticks (mainly a risk for healthcare workers)

3. Mother to Child:
- During pregnancy
- During childbirth
- Through breastfeeding

Important to know:
- HIV CANNOT be transmitted through:
- Casual contact (hugging, shaking hands)
- Sharing food or drinks
- Swimming pools
- Mosquito bites
- Saliva, tears, or sweat

If you're concerned about HIV exposure, please consult a healthcare provider immediately. They can provide testing and discuss prevention methods like PrEP (Pre-Exposure Prophylaxis) or PEP (Post-Exposure Prophylaxis) if appropriate.
