I walked past a man yesterday on the street who had a big cut on his forehead which was bleeding. When i got into my college i noticed i had 2 small bllod like marks beside my nose. The thing i fear is that when i was walking past this guy some droplets of his blood managed to get on my face. I then wiped the marks off but they were quite stubborn so i had to scratch them off and then the wee marks started to bleed. Could i get HIV this way as it is blood to blood contact? Teak and Lizzie please answer.
