question: Hello doctor,  I am a lab worker, at the time of the incident I was standing in front of an empty centrifuge and as I held one of the tube inserts upside down to clean it, speks of dried blood fell out of it. I am not sure if any of it went into my eye and I am worried. I wanted to ask if HIV can survive in those dried blood flakes.I am really stressed, it has been 2 weeks since the incident. I am up to date with my hepB vaccinations. At the moment I have a bit of sore throat and 37.1 degree fever and I am really scared. I did see a doctor on the day of the incident who reassured me that I am not in danger, I also wanted your expert opinion.
