Yes, as you've been told.
one more answer please, if my son has cuts on his finger? still no risk from scratching ?
It is very fragile virus and with seconds after leaving its host, it becomes unstable (loses ability to infect). Nobody ever got HIV in this way so you really don't have to worry about this!
So hiv negative guy scratches hiv positive and still no risk? Any one else can also reply me?
No risk. HIV is transmitted by unprotected penetrative anal or vaginal sex, sharing works with IV drug users, mother to child.
