Hi,
Recently a colleague and I were sharing a cubicle and he had a nasty cough. On more than one occasion he coughed on me. What worries me is that he mentioned that there were traces of blood in his phlegm. While I don't know about his HIV status I wanted to know if I am at risk.
In case some of his phlegm/saliva mixed with blood fell on my eyes, nose or mouth would that be a transmission risk?
I would like to point out that I did not have any open cuts or sores in my mouth.
