I find myself worrying very much when my hands are scratched (scratched meaning that when I pour alcohol over the scratched area, it stings!) and I have to shake hands with other people, who maybe are also scratched. I saw on different occassions this happening, and it is a very stressful situation for me. Can this corporal contact between scratched hands or scratched area on the body and another scratched person, or this person's saliva, lead to infection with aids, supposing the stranger is a bearer?
And also, very important for me. How long does the virus live once ejected from the bearer's body? I mean, an infected person bleeds on the streety, and I walk aover that stain, and then I walk in my house, then drop my jacket on the floor, then I touch the jacket again etc. Is it dangerous? How much does this virus live once ejected from the stream blood line?
I recommend that you look in your local telephone book and look for your county's board of health office and make an appointment to talk to someone about hiv and aids. They can answer all your questions, if this is not available call a local hospital and see if they have someone who can answer them. Best of luck.
