I am 15 year old and I want to know that what are some HIV facts that I must know. My friends were talking about all this yesterday and I was not able to participate in their talk as I don’t know anything about it. Do you think is it good to talk about all this at this age? It will be really nice if you can give me some facts which you think I must know? I have heard that If I will take blood I must check that the blood is HIV negative. Is this correct?
