i use my room mate tooth brush five minute after he finish using it.what are my chance of getting hiv?
The risk of getting HIV by sharing a toothbrush depend on a few things:
- How much virus is in his blood? A high viral load would increase the risk.
- Was there any visible blood on the toothbrush?...that would increase the risk
- Did you have any bleeding or sores in your mouth?...that would increase the risk.
Overall the risk would be very very small.
