Last week I went hospital to get treated for cold sores at my outer lips and mouth area. While waiting for the call by doc I went to public toilet. When I about to open the door there was a man about to come out from the door and started to sneeze twice and I could feel his sneezing somehow touched my face and cold sores at outer lips and mouth area. I am very scared and nervous(severe anxiety) because my cold sores were bleeding during that time and would like to know whether this incident could cause hiv infection. Pls help to guide and advice on this. Thanks alot.
