I was on the street in Vietnam and a few people (drug users) were fighting and bleeding, at one point i saw a drop of blood enter my eye. as a natural reflex, i used my finger and my shirt to wipe it out. i don't remember washing my eyes afterward cause i was on the street. now i am worried hiv blood got into my eye, and by the actions of wiping and rubbing eye, i caused some damages or scratches in my eye which made entry for virus to infect me. do i need to worry about the incident? do i need a test? thank you so much for your professional answers
