Wanted to get your thoughts on dried blood on coins. Someone gave me a coin with definite blood on both sides of the coin, seemed dry. I handled it, touching the bloodied areas, and told the chemist I don't want that one and I don't want to catch diseases. He handled it and put it back in the till after surmising it may have been dirt but then seeing it was actually blood, and gave me another coin. So everything I have now touched is contaminated, including car wallet, garage opener, clothing and so on. HCV lasts 4 days in dry blood, but I can't quarantine all these contaminated items for that long, and Dad has now touched the garage opener after I asked him not to. I don't know what to do. I can't get a conclusive test for 6 months. What should I do?
