A stranger sprayed a small drop from her insulin pen on my lip before injecting herself, accidentally of course. I don't know her status. I wiped my lip. I was drinking from a can at the time, I took a sip before thinking I should wash my mouth, which I then did. I don't know if that lady re-uses needle tips or if her insulin could contain traces of fluids. Is there a risk of HIV in that scenario? I would think there might be a hepatitis risk, though as it was my outer lip and not inside my mouth, I hope it's not much.
Thanks for any help!
