Hi,I got cut by my hairdresser with a razorblade.The thing is it all happened too fast that I didn't look to see if the razorblade was new in the first place.Well,if she was hiv positive,could she infect me in this way when she cut herself secretly before cutting me?the cut was rather very tiny,I immediately disinfected it with aftershave.

I wouldn't worry too much about it to be honest. Get yourself checked out if it will calm your mind. You would need a open wound on her hand that dripped in your razor cut. As well as her being HIV positive in the first place.

This just sounds like a touch of paranoia.
