Scientific research says coronavirus can be transmitted through flushing

 Since the new coronavirus pandemic, scientists have been trying to determine how the virus spreads. We all know that it is dangerous to approach people infected with the virus without face protection, but it is also important to protect yourself from unknowingly infecting the virus. After the toilet flush, the particles continue to come out of the recently flushed toilet for up to a minute, forming a lump of aerosols that can carry the virus if a person is infected, the researchers said. Now, a new study seems to support previous research, pointing to a pathway to toilet-related transmission.

It turns out that a toilet that opens the lid to flush it becomes a fecal pellet bomb, and since we know that coronavirus can survive in feces, the toilet is a potential infection. Businesses across the Country, in particular, are reopening, and many public toilets are covered with no lids, which is all the more worrying.

The study, published in the journal Fluid Physics, looked at how particles were blown out when flushed in a toilet. It is well known that flushing produces aerosols or particles in the air that are then inhaled and then placed on other surfaces. If a person is infected with coronavirus, these aerosols may contain the virus, and people who go to the toilet there may be infected themselves.

The researchers say that from daily experience, flushing the toilet creates strong turbulence in the bowl, and will the turbulence caused by this flush drain the aerosol particles containing the virus out of the toilet? Using computational fluid mechanics, the researchers explored and visually understood the characteristics of fluid flow during toilet flushing and the effect of flushing on the spread of viral aerosol particles.

Earlier studies from China appear to have shown that air particles from flush toilets are a viable way to spread the virus. Studies have shown that in typical cases, feces-mouth (particles fall in the mouth) and feces-absorption (inhalation of tiny particles containing the virus) are possible. The latest round of research supports this view, revealing that particles around the toilet after flushing can remain in large lumps of aerosols that can continue to be transmitted from the toilet to the air about a minute after the flush starts.

The scientists found that the dock flushing produces strong turbulence, producing an up-to-5 m/s rise rate, and of course, the aerosol particles can be discharged out of the toilet, about 40-60% of the particles can rise above the toilet seat to cause large areas of diffusion, such particles from the ground altitude of up to 106.5 cm. Even during the post-flushing period (35s-70s after the last flush), the diffusion particles can rise at a rate of 0.27 cm/s-0.37 cm/s and continue to climb. Scientists say spread can be reduced by closing the toilet cover before flushing.
