I appreciate the clarification, but I also know that generally the people who work with pathogens practice better epidemiological controls than the people who buy bush meat. My mother did epidemiology. She knew a few cases of accidental exposure to nasty shit - one of her coworkers actually injected himself with anthrax and another exposed himself to rabies. But at the same time, my sister spent two weeks in the ICU with hantavirus and I lost a classmate to plague. Yeah crud leaps out of petri dishes sometimes but there's an ocean of the stuff out there just past where the streetlights cease to shine.
I have less faith. I've seen scientists do things that no one with an advanced degree in science would be expected to do. Things with radioactive material, body fluids, cultures. Everyone has stories. Lab casual. It's a thing. Sometimes the worse offenders are those that have been in the lab the longest.
