I would doubt we will ever know with certainty if the lab was involved or not. With respect to where did the infection come from if we all agree it spread from the market, what I can say living on a farm is that viruses and bad ones can and do mutate and leap between humans and other animals. Origin in the lab or market aside, for the sake of humanity these types of unsanitary conditions of animals and people in close proximity needs to end as does the notion of eating inadequately prepared and cooked bush meat.
