I never have an unprotected sex, and no sharing neddles with others. I go to a regular hospital when I am sick. In this way, do I still have a chance to get Infected. Would an open would cause me troubles? I did a test by myself, and it showes negative. I heard that in some Asian area, some people use their needles to make other people infected maliciously. Would that be a risk for me as well. I find that my body with some small scars time to time. Does it means that I am at risk?
