How big is the Corona-is a danger to public toilets?

Experiments by Chinese researchers show that virus particles could distribute in the toilet flushing in the air. Accordingly, it would be possible with a disease to infect that virus with the stool to be excreted. The novel Coronavirus is one. But there are simple counter-measures.

Sometimes it cannot be avoided to use a public toilet, and there you can plug in might be a virus: A study from China shows that a large number of particles, among which a virus could, on the toilet seat, in addition to a large area of and a height of about one Meter &ndash can spread; up to 70 seconds after flushing. This, the researchers report in the journal "Physics of Fluids".

The researchers, therefore, to close the toilet lid before flushing, because that is Transmission of viruses can be prevented in principle. Before use you should clean the toilet seat because the virus could have particles deposited previously on the surface. And to wash finally, as a matter of course: After using the toilet, the hands carefully to remove any virus particles that may have been on the Spülknopf and the door handle.

How high is the risk of Infection is?

But how big the risk actually is? In a in the journal "JAMA" published study, it was demonstrated in 40 percent of the SARS-CoV-2-Infected genetic material of the pathogen in the stool. This does not mean, however, that it is also infectious viruses: Only two of 153 samples (1.3 percent) were propagation observed in viable virus. The risk of Infection on public toilets is likely to be in comparison to a direct contact with the Infected, therefore, very low.
