Unprotected Sex and HIV Risk: Infection Rates?
How Is HIV Transmitted?
HIV spreads through specific body fluids:
๐ Blood
๐ Semen
๐ Vaginal fluids
๐ Breast milk
Risk of HIV Infection per Exposure
Average risk based on research (per single exposure):
1. Vaginal Sex
๐ Risk: 0.08% - 0.1% (~1 in 1,000)
2. Anal Sex (especially receptive partner)
๐ Risk: 1.4% - 1.7%
๐ Higher risk due to fragile tissue and microtears
3. Oral Sex
Very low risk
๐ Open wounds in mouth
๐ Bleeding gums
What Is PEP (Post-Exposure Prophylaxis)?
PEP is an antiretroviral treatment taken after exposure to prevent HIV infection.
Key Conditions
๐ Must start within 72 hours (3 days)
๐ Best effectiveness if started within 2 hours
๐ Must be taken continuously for 28 days
Effectiveness
๐ Reduces risk by 80-90%+ when taken correctly
If More Than 72 Hours Have Passed
PEP is no longer effective
๐ HIV testing
๐ Safe sex practices
๐ Avoid further risk
HIV Testing Timeline After Exposure
4 Weeks (1 Month)
๐ First test
๐ Detects most infections (4th generation test)
๐ Not yet 100% conclusive
12 Weeks (3 Months)
๐ Follow-up test
๐ Accuracy: >99% (confirmatory)
24 Weeks (6 Months)
๐ Optional (high-risk or immunocompromised individuals)
Summary
๐ Unprotected sex carries a real risk of HIV infection
๐ Even if percentages seem low, consequences are lifelong
