As the world’s population continues to respond to the pandemic of coronavirus, scientists are desperate to find out the ways in which the virus can spread. While the main mode of transmission is still close to an infected person, research now shows that bathroom fixtures can be dangerous.
In particular, the toilet.
Toilets have always been a potential pollutant, as streams spray viral and bacterial particles nearly 3 feet in the air. In the age of coronavirus, that risk has taken on a new meaning. In a story for The New York Times, Knvul Sheikh reports that there is growing evidence that a flower toilet can create an aerosolized cloud of infectious grains. This coronavirus risk zone can then lie down, inviting inhalation by the next person to use the facilities.
According to a study published in the journal Physics of wetness, the concern arises from the presence of the virus in feces. Although it is primarily a respiratory illness, coronavirus can also take up residence in the small intestine and cause digestive illness. As soon as the virus enters human waste, toilet action can flush the particles up. The movement of the incoming water creates a vortex, removes air and acts as a germ gun.
Although it is clear that the virus is spread by flies, scientists still do not know the extent of the infectious virus in these clouds. The best thing to do is to close the roof of the toilet before flushing, which should alleviate a lot of air pollution products. Sick household members should use a separate bathroom if possible.
Public bathrooms are more difficult, as many more people use them and often do not have leads to closures. For now, it may be best to avoid these places of rest if you can. Wearing a mask can also reduce some of the risk. And always wash your hands.
