Hi, I clapped a mosquito which sucked blood from my colleague just few seconds before, now I'm scared that the mosquito might sting me when I did the clap. I know that mosquito cannot transmit HIV but in my case it happened very fast, my colleague status is unknown but assuming that he's HIV+, what is my chance of transmission ? Thanks
The risk is zero. There is the concept of inoculum in infectious diseases. This is the amount of a germ necessary to lead to infection. For HIV the inoculum is relatively high. Small amounts of virus does not lead to infection.
There is no risk here at all.
