text: if a person got no aids,how can he pass aids to someone without using a infected needle?any medicine for that?   if a person does not have aids, then obviously they can't pass it to anyone.  if a person does have aids, then they can definitely pass hiv to someone through a used needle. there might be a small trace of blood from the infected person, and if someone uses the needle after them, they might get that small trace in them.   also you don't get aids from someone, you get hiv. aids is later developed from hiv.
