Hello,
I had a cold three days ago. Due to using handkerchiefs, some of my nose skin were scraped. My nose is okay now. But There are some dead skins around my nose. Today I shook hand three or four times with a person who is HIV positive. I have touched my lips and outer nose skins with unwashed hands afterward. Now there are no cuts in my hands and nose, not that I can tell. And there was no cut in his hands either. Can I be HIV become HIV positive. And He wants to use one of my blankets and pillows. What would be the risk of HIV transmission then?
