The case that you have mentioned is quite dangerous. If the salon uses razors/blades for manicure and they are infected by HIV, there is a possibility. Because the virus can be transferred when you are bleeding and have a cut. Get your test done as soon as possible and be safe.
No you can get hep c or b or b a just as bad
I'm not agree at all. I don't think it's so dangerous, there is only a little possibility. Every salon should clean the tools after every person, and situation above is unlikely. There has to be about 2 or 3 drops of fresh (wet) blood directly in your broken skin. Virus dies very quickly on the air. I haven't heard about that kind of cases. Get tested always if you have any doubts 3 months after the happening.
No, I don't think so
Everyone is so quick to answer NO and say the salon "should" clean instruments after each client. Should is not doing it! I see these nail shops working faster than a mechanical assembly line and not following safety & sanitation rules. HIV can live outside the body for two hours, a nail tech can do four people in that amount of time. Get yourself tested and start doing your own manicures & pedicures. At the end of the year go take a vacation with the money you saved.
