Hello Dic, I am worried about a incident which was happened 3 days ago. I went to see a building construction site. When I was keen on visiting the work, One of the worker by mistakenly place his bare foot on my toe fingers. His foot had sand and are little bit wet. The sand was landed on my toe's first and second fingers and also on my nails. I am worried suppose If his foot was bleeding and put his leg on my toe, is there any risk for diseases like HIV? I did not have any visible cuts on my toe and fingers. But my worry is tha nail area of my toe from which any particle can enter. I can't concentrate on anything doc. Pls solve my issue UPDATE: I have checked my foot and toe. There were no cuts and sore. But there was a small dot like area where a portion of tiny upper akin is peeled off. It was not red which is considered as way for blood path. It was white and not even any colour of red. Should I worry about this incident. What is the worst case in my scenario. Many say HIV spread through deep and fresh cuts. Although it's a virus why can't it enter through tiny peeled off skin. Help me elaborately. I am having sleepless nights. Doc pls explain the situation as I have nobody to trust in this. Only you doctors should help me.
