Hi,
I about 4 days ago cut my thumb with a knife at work and it started to scab, I went to the bathroom and touched the flush button with this thumb expose the cut to the button. As I am female, I am worried that there might be traces of microscopic blood on the button as females get their period and sometimes when inserting tampons, blood gets on the finger and then they use that to press the button. I’m not sure if I had opened my scab as there was not any fresh blood. Could I be at risk?
