Hi, I went through your question and understand your concerns.
I hope by now the
vomiting has ceased.
From my personal experience, it is very unlikely to be infected by
HIV just because water from the toilet splashed on your eyes and face. There is no publication or research that proves it otherwise as well.
Considering the most recent findings, physicians worldwide, still consider HIV only spreads through direct contact with blood, semen, pre-seminal fluids, rectal fluids, vaginal fluids, and breast milk of an HIV positive person.
Considering the fact that you already flushed, I am pretty certain that there is no scope of virus transmission.
Although, if you are still anxious and concerned, please get a
blood test to rule out any possibility of HIV considering the fact you work for an HIV clinic.
Also, I thank you for working for HIV positive individuals.
Hope I have answered your question. If you have any further questions we will be happy to help.
If you do not have any clarifications, you can close the discussion and rate the answer. Wish you good health.
