Publicly available satellite images from NASA's Fire Information for Rescue Management System (FIRMS) show dramatically increased open-air fires during the period of the Wuhan virus outbreak from Jan. 11 to Feb. 11, versus the month of October, 2019.
The image below shows open-air fires in Wuhan (LAT 30.5, LON 114.6) in October 2019, which precedes the earliest reported cases of the disease. In this image, a few scattered fires in dark blue signifying a "fire radiative power" (FRP) of 1 and light blue, signifying an FRP of 5 can be seen.
There currently are eight registered funeral homes in Wuhan. If the account of the funeral home staffer is true, this would mean there are 1,628 deaths per day in the city and 34,200 over the past 21 days.
