Nine people fell ill in a residential building in Guangzhou, there were no deaths. The investigation was carried out by the Centers for Disease Control and Prevention of this city, and everything was published in the “Annals of Internal Medicine” where it is stated that a family of five who lived on the 15th floor was infected with corona in January this year, after returning from Wuhan. as well as subsequent cases of Kovid in pairs on floors 25 and 26, using the same plumbing system, and who did not travel or were in close contact with those infected. There is evidence to suggest that the spread of infection was due to fecal aerosols.
The case recalled the spread of SARS in 2003 through a pipe in a residential building in Hong Kong, and some fear that an epidemic similar to the one that paralyzed New York could erupt down the toilet, writes “Sciencemag.”
A case study from China emerged after months of warnings that SARS-KOV-2, caused by Kovid-19 and believed to be transmitted primarily by droplets and aerosols, could be spread via the fecal route.
“It’s not something that people like to talk about,” wrote Joseph Allen of the Harvard School of Public Health in an article published this week in the Washington Post.

Although fecal transmission of pathogens is difficult to prove, and it is even more difficult to prove that the virus spreads through sewers, the “ScienceInsider” researchers claim that such a thing is still possible.
Numerous studies have written that SARS-KOV-2 RNA was found in fecal samples from patients with Kovid-19. Some patients had diarrhea, suggesting that the virus had infected their intestinal tract. RNA can also be “passed on” by swallowing saliva that contains viruses. Wastewater is being tested around the world (for example, in American universities) to monitor epidemics.
During some investigations, abundant amounts of corona virus RNA were found in hospital toilets, and one study indicated that by releasing water into the toilet bowl, virus particles can be flushed far above the bowl. By inhaling aerosolized fecal matter or swallowing the virus after touching contaminated surfaces, people are exposed to the virus, writes “Sciencemag.”
For the purpose of further research, it is still necessary to test whether the virus RNA in the stool comes from the remains of live or destroyed viruses. Only a few laboratories reported isolating live viral particles from stool samples of Kovid-19 patients.
A team of scientists suggested that intestinal fluid neutralizes the virus, while the US Centers for Disease Control and Prevention said it was not “clear” whether the virus in the stool could cause Kovid or not, but concluded that the risk of this way of spreading the virus was low. . There are currently no documented cases that clearly indicate fecal infection.
However, whether the risk of infection is present in the sewer system is another matter. While fecal waste makes its way into a typical sewer or treatment plant, potentially intact viruses are likely too elaborate to be contagious, according to Yale University engineer Jordan Pechia, who is investigating the presence of a new strain of coronavirus in Connecticut sewage. To date, there is little evidence that Kovid-19 is spreading through the sewers.
