After potential occupational HIV exposure, what is the recommended action?

• A. Start post-exposure prophylaxis within 72 hours
• B. Wait for baseline serology
• C. Do nothing
• D. Only observe

Answer: (A)

After a potential occupational exposure to HIV, act quickly: start post-exposure prophylaxis as soon as possible, ideally within two hours and no later than 72 hours after exposure. Beginning PEP promptly can significantly reduce the chance of HIV infection because it suppresses viral replication during the earliest window when infection could take hold, even if the initial HIV test is negative. Baseline HIV testing is important, but it cannot rule out acute infection that isn’t yet detectable. Therefore, waiting for serology before starting treatment is not advisable. The usual approach is to initiate a 28-day antiretroviral regimen, with follow-up HIV testing at intervals (such as 6 weeks and 3 months) to confirm status and monitor for side effects. Also check vaccination status for hepatitis B and provide appropriate follow-up and counseling to ensure adherence. Options that involve doing nothing, observing, or waiting for baseline serology miss the preventive benefit of early PEP, which is why starting within the 72-hour window is the recommended action.
