Beijing – The discovery of coronavirus in the bathroom of an empty apartment apartment in southern China is being taken as evidence that the pathogen was spread through the sewer pipes after the toilet was flushed in one unit. This finding is adding to the anxiety Ability to spread the virus in small airborne particles In closed spaces, and not in the same room, or even on the same floor.
The Chinese still remember Outbreak of SARS virus by a man Who visited the Amoy Gardens apartment building in Hong Kong 17 years ago. Eventually his visit to an apartment made more than 300 people in the building sick, and the virus, which causes Covid-19, is thought to have been spread by plumbing.
Genetic material showing the presence of the new coronavirus was found on surface samples from a sink, faucet and shower handle in the bathroom of a long-vacated 16-story apartment apartment in Guangzhou in February.
The apartment apartment is directly above the bathroom of the apartment in which five people confirmed the COVID-19-PO positive in late January, according to a study recently published in the International Journal of Environment by researchers at the Chinese Center for Device Control and Prevention.
Scientists conducted an experiment in the building, flushing the toilet in the apartment on the 15th floor and then finding aerosolised viruses in the units above.
“After flushing the toilet in the 15th floor restroom, the possibility of transporting the aerosol through the sewer pipe was confirmed,” the study concluded, as the virus aerosols were found in the bathrooms of the 25th and 27th floor apartments of the same building, directly above. Suspicious source.
Four COVID-19 cases were confirmed on those two floors in early and mid-February, according to unpublished data from China’s CDC regarding the study.
“Evidence suggests that the transmission of CARS-COV-2 by aerosols is favorable under favorable conditions,” the researchers concluded, noting that the virus travels not only through small particles in the air, but also through large droplets.
However, transmission by shared elevators cannot be ruled out, “this incident is consistent with the findings of the 2003 Amoy Gardens SARS outbreak in Hong Kong,” the report said. The leading theory of that outbreak focused on sewer backups in the Partition Building, where the virus may have been aerosolised.
Chinese researchers say that with the Covid-19, “the toilet is an everyday necessity, but it promotes fecal-derived aerosol transmission, especially if used improperly in hospitals.”
The World Health Organization came under pressure this summer and eventually admitted that, in addition to the droplets, airborne particles could not be ruled out, as some reports of COVID-19 outbreaks, especially in indoor settings with poor ventilation.
