Hello everyone. I'm a HIV carrier who has accepted the treatment for a half year. Two weeks ago my arm was broken bleeding a lot and my friend helped me to go to the hospital. I'm sure he touched my blood stained some on his hands and didn't wash hands. About two hours later, he argued with someone and got some bleeding scratch on his hand. I worried that if he would be infected in this way and I asked a doctor said my friend was okay. However after two more weeks, he caught a cold, not serious but lasted long. Now I get worried again. My question is, Was there any probability that my friend got infected? I need a final answer please. Thank you so much!
