(4) Now in June, a 6 person outbreak has occurred in one building, which was spread to neighboring markets.
The source of the virus may be sewer gas.

(7) Most people realize that CoVID-19 has been found in patients' stools and sewer systems, but recent research shows that it can remain viable for up to 25 days. The United States has been identified as a country with a high relative risk.

For Wuhan this was high priority.

(9) The infographic they shared made a point of the fact that #COVID19 hospital patients and those at the quarantine center were shedding virus into the city's sewer system, that actually shares its sewer pipes with the residents.

(11) During the 2003 SARS outbreak, the largest super-spreader event in Hong Kong involved transmission of the virus via sewer gas and aerosols.
Hong Kong's vigilance has allowed them to discover smaller related cases involving the spread of COVID-19 in 2020.

(12) Recent research shows COVID-19 can stay viable in sewer water for up to 25 days, preferring water around 10-20 C (40-68 F).
Wuhan made it a top priority to disinfect their sewers.
