A group of six miners working to clear guano from a copper mine in the Mòjiāng region of south west China contracted acute pneumonia of unknown origin. The disease symptoms resembled COVID-19. The disease was non responsive to antibiotics or antifungals. Also similar to COVID-19, the prognosis was poorer the older the patient. Two patient passed away. First admission was and last discharge was 1.
The location of the mine is thought to be N 23°10’36’ E 101°21’28. Due to the similar nature of the disease to COVID-19, interest in the mine resurfaced after the pandemic. Attempts by journalists to reach the mine were thwarted in late 2020 and earlier 20211.
Most documentation about the event derives from a medical thesis by Li Xu in May 20131.
