Q: When a person comes to know he is affected by HIV/AIDS and if his blood after six months of the incident shows negative, can he believe it? I tested my blood after 4 months and it is negative. Then again I tested my blood six months after the exposure. The results were negative again. Shall I believe this or you want me to test it again?

A:You are fortunate because in spite of exposure you have not got HIV infection this time. If the test was done at a good laboratory you can believe this report and do not need another test. However please understand that the next time you engage in unprotected sex you may not be so lucky. Do not take a chance -- you have only one life and it is too precious to waste. And also don't forget that HIV infection does not only affect you but also those that are close to you.
