3 days back i had an accident where a person on scooter hit my car and fell, he had some muscle injury on back where i applied first aid ointment from a car and there was a wound and blood on his knee as well which was not flowing downwards but was still, i applied the same ointment there as well (2-3 min after accident) and have only poured cream directly but may have also used my finger to apply it which i dont remember exactly and now what haunts me is HIV through blood contact.

just to be sure 

do you think there is a risk of HIV Exposure here or should i put this incident behind and move on?

your advice has always helped me a lot Doc 

Thank you
