The first thing you can do is to consult your doctor. He will ask about your health history and might let you undergo certain physical examination. Your laboratory test result will show if you're infected or not. So, if you see some blisters around your genitals or your anus and butt cheeks, you might want to consult a doctor before the virus spreads all through out your body. This virus is actually incurable, but early diagnostics will help you prevent greater suffering.
