It’s really an open and shut case
FLUSHING the toilet could help spread the deadly coronavirus by blasting long-lasting clouds of particles up into the air, a new study warns.
Recent studies have shown the virus, which has killed more than 430,000 people worldwide, survives in the digestive system and can show up in human faeces.
Study co-author ji-Xiang Wang, of Yangzhou University in China, said: “One can foresee that the velocity will be even higher when a toilet is used frequently, such as in the case of a family toilet during a busy time or a public toilet serving a densely populated area.”
Flushing a toilet creates turbulence in the water and air, which is known to spread bacteria and viruses, say the findings published in the journal Physics of Fluids.
Wang said: “A solution to this deadly problem is to simply close the lid before flushing, since this should decrease aerosol spread.”
Public toilets in many countries, however, are often without a lid or cover.
The researchers hope the findings could prompt a better toilet design, with a lid that closes automatically before flushing.
