I have a number of questions about routes of transmission of the virus (B and C). 1. In dental. Interested in this situation. Suppose, sterile instruments are not in doubt. But here's a lamp, which corrects the doctor from time to time during treatment. It can remain particles (drops, the point ...) of blood, which, when touched gloves lamp fall on the gloves, and then the doctor continues to treat them the same teeth, touching the teeth and bleeding gums. Thus, there is the risk of transmission of hepatitis? 2.Vtoraya situation. At the entrance of splattered blood. She may be on the door with combination lock. And children in general about the dangers do not know. Situation. The child opened the door (on the fingers were pieces of blood). Hands in your mouth. Thus the virus transmitted? 3. If there are no visible traces of blood, can I get it? Situation. For example, someone cut himself, then grabbed the handle in a public place, the blood was dry. Blood is not visible to the eye. But some of its particles are present. When you touch the handle, the particles of blood fall on the hand. And if at this time porezatsya in the same place, or hand lick? There is a risk? Thank you in advance.
