Hello, So sorry for asking this question as I read the latest post below that wound to wound transmission is very low to negligence.
I was helping a tradesperson move something where I needed to hold a strap with my hands inside his hands. I had a band-aid that I had placed on my knuckle 30 minutes earlier as I cut myself so there was a little blood at the time.
What would the risk of infection be if the tradesperson transmitting anything to me in this way through rubbing motion of their hand on my hand if they had a cut on their hand themselves before I helped them. My bandaid did move upwards as we were both pulling on the rope/strap so the cut was visible.
1) Having unprotected anal or vaginal sex, or
2) sharing intravenous needles with IV drug users.
Wound trauma is NO RISK unless the trauma and bleeding are so severe that one or both parties is at risk of death from blood loss.
