⚠️Fecal aerosols... 9 infections in 3 families due to vertically shared toilet drainage pipes + aerosols from pipes. To even prove it, tracer gas was released into drainage system of one unit & shown to come out of the other. ➡️Fecal airborne transmission is real. #COVID19

The articles on the Amoy Gardens outbreak of SARS-1 are worth reading. The key article is nejm.org/doi/full/10.1056/NE… and the government report that it both builds on and partly debunks is legco.gov.hk/yr03-04/english… .

In the Amoy Gardens SARS-1 outbreak, the virus was originally spread through the toilets, but the aerosols then caused wind-borne transmission to adjacent buildings! Really, the lesson is to make sure your U-traps don't dry up. Or maybe don't build bathroom floor drains?
