HIV prevention is strongest when several tools work together: condoms, sterile injection equipment, regular testing, PrEP for ongoing risk, and PEP after a possible recent exposure. Treatment also prevents transmission when viral load remains undetectable.
PEP is time-sensitive and should be started as soon as possible within 72 hours after a possible exposure. PrEP is planned prevention for people with ongoing risk and requires periodic HIV, kidney, and STI monitoring.
Testing windows vary by test type. A negative result immediately after exposure does not always exclude infection, so follow-up testing is important. Partners should avoid blame and focus on care, testing, and prevention.
HIV is a manageable chronic condition with treatment. Early diagnosis protects health, prevents transmission, and reduces fear created by outdated misinformation.
