Road traffic accident contact

Question: 

Hi, iam Ramesh from india
I had a small wound (2mm) at the dorsal side of my left middle finger with little blood. After half an hour while travelling , saw a man (lorry driver) got injured at road. He had multiple cut wounds but blood has already dried. I helped him by holding his hands and legs. Some amount of sweat and mud over his body came into contact with my palms but not at my wound. After that i washed my hands with plain water.
Iam afraid that his sweat could have mixed with his blood and it would have come into contact with my wound during hand wash. Also high number of lorry drivers in india have hiv, though iam not sure about this person..
Kindly advise..

Answer: 

Hello,

Thank you for your inquiry. From what we gather from the question, you were asking about acquiring HIV through a small wound from dried blood mixed with sweat. From the information given, this scenario is determined to be No Risk because transmission of HIV is not possible in the given scenario.

The scenario mentioned above does not meet the three components of the transmission equation. It does not satisfy the equation because HIV is rendered inactive when exposed to oxygen and there is no HIV in the fluid of sweat.

Recommendation: No need for HIV test with the scenario provided, refer to a physician for other health related questions.
