For exposures not turning into pandemics, I think it's also important to note that most bat/human coronavirus crossovers occur in relatively small communities that limit the size of potential super spreader events. In something like the original form of Covid-19 where most people infected don't infect anyone else and the small number of people who infect hundreds are the main driver of the high R we can't necessarily generalize from what we see in rural Yunan and SE Asia to what we'd see in a big city. Though regardless of the origins of Covid-19 I do worry about these regions getting more connected to the global economy.
