Hi Doctor, I've been scrambling a lot of thoughts in my head due to a recent incident . had. At the supermarket one lady dropped an item from a shelf and I leaned forward to pick up the item from the floor in an atempt of courtesy, the lady leaned too trying to reach the item as well, and she reached my hand and she scratched me with her little finger nail, i did not bleed but just had some irritation on my skin from the scratch, I know it is hard to know the hiv status of a person but assuming she was hiv + and was not following treatment, what are the possibilities to become infected from this incident? I took a test 6 months ago over an incident 3 months previous to the test and it was negative. After this test I havent engaged in any activities that are considered risks for acquiring hiv and i am a bit paranoid over this incident. Should i get tested again?
