I'm going to go ahead and say probably not. Viruses that originate in animals spread to humans all the time. One time I had a patient who got pneumonia from lactobacillus gasseri. Do you know where that is commonly from? The lower reproductive system in women; the vagina. Pathogens find themselves all the time in humans that have an n=1. Why don't we constantly have pandemics? Because human to human spread requires very specific genetic changes for that to occur. How often does this happen because someone was doing research on Coronavirus and it accidently got released from a biosafety level 4 lab? Not often. How often do novel Coronaviruses spread from bats to something to humans? All the damn time.
