I would like to listen some answers from you, experts. Just for my own knowledge. I've been searching for the information on the WEB and speaking to some doctors, but answers are prety much different.
As we live in the world of bacterias and infection possibilities almost on every corner, there is something that we can't prevent - physical contacts with other people with unknown statuses.
I'm sure, that everybody has gotten scratches in his everyday life, you can't run out of it, and those scratches could be from contact with other people (mostly nail scratches). Doesn't matter - we can get them during basketball match, paying in supermarket, handshaking etc...
My question is, what, in your opinion, is the risk of getting STDs, escpecially all types of Hepatitis, HIV and syphillis through the situations described above, considering that scratches are slightly bleeding and not very deep and had been gotten from person's nail, who is infected and has a little amount of his blood on the nail.
