Hello,doctor.My English is poor and i will try my best to explain what im worried about.If there are some of what I said that you can not understand,please let me know,thank you.
Yearstoday I went to an Internet cafes and found some dark red spot ( i'm sure that no one touch the chair in at least five minutes but i'm not sure if the spot is dry,maybe wet) on the armrests which coverd with cloth and I tried to get it off with my fingernail,the spot became small but i didn't know if it stick to my finger.Then A minute later I used this finger to squeeze the whelk on my face and got some blood out.
Now i am worried if the spot is blood with The AIDS virus and the bleeding whelk on my face could contract it.then I collect a lot of information on the Internet.But in my country,there are a lot of argument.Someone say that The AIDS virus in blood die as soon as the blood get out of body, others say that they can live longer outside,as long as the virus is in the blood and no matter if the blood is outside out body.Someone say a few minutes,someone say a few hours,someone even say a few days.Who should i believe? I heard that you are professional so I come here.Please let me know if I am in risk,Thank you very much!
