I work in Africa now, I was wounded by wire in twelve days ago(now 2016-10-12), Right hand little thumb broken skin ,There was a slight bleeding from the wound,The blood is almost impossible to seep out. I use saliva immediately disinfection and wipe it with hands. The wound could not see the bleeding again. Half an hour later, I used 75 degrees of medical alcohol disinfection .There is no pain in the wound,I can guarantee that the wire has not hurt anyone else in 5 minutes. The wire is about a millimeter in diameter,If a man was stabbed by the same wire in 5 minutes ago,This person has been infected with HIV .Could I possibly be infected ??
