A friend was exposed 40 days ago after intercourse with now known HIV positive lady, pep started on day 4 only. On pep completion, pcr and Elisa negative. On day 39, negative combo. He got me worried when he showed me some rare fine rash one or two on the forearm and same onthe shoulder, he mentioned one episode of soft stool today...maybe prolonged or late effect of pep?! Can I hope to be negative?
