Q: I am a 28 years old male and indulged in casual sex last year in June. During the act, my condom broke. I was tested negative on 88th day post exposure. What are the chances that I have got AIDS?

A:The chances are very high that you have not got HIV infection. However, to be certain another test should be done after some time as in rare cases the window period may extend beyond 3 months, and for this reason testing again at 6 months is sometimes suggested. I must assure you however that this late manifesting of infection is very rare and I am confident that you are safe.
