This is not the original story I read, but it state sthe same stuff about the 2012 cave incident where miners were infected.

In October 2015 Shi’s team collected blood samples from more than 200 residents in four of those villages. It found that six people, or nearly 3 percent, carried antibodies against SARS-like coronaviruses from bats—even though none of them had handled wildlife or reported SARS-like or other pneumonialike symptoms. Only one had traveled outside of Yunnan prior to the sampling, and all said they had seen bats flying in their village.

Three years earlier Shi’s team had been called in to investigate the virus profile of a mine shaft in Yunnan’s mountainous Mojiang County—famous for its fermented Pu’er tea—where six miners suffered from pneumonialike diseases and two died. After sampling the cave for a year, the researchers discovered a diverse group of coronaviruses in six bat species. In many cases, multiple viral strains had infected a single animal, turning it into a flying factory for new viruses.
