It is a shortage of toilet paper may not be your larger toilets related to the pandemic are worried this fall. If you do not wear a face mask in public toilets during the pandemic, you may want to start. Why? Two words: infectious particles. Rinse a toilet or urinal can release coronavirus particles in the air, a new study indicates.

In a study published Monday in the newspaperFluid physicsChinese researchers say that urinals can be even more infectious than toilets because they produce an "alarming upward flow" of particles that "travel faster and fly further than those produced by a hunting.

"Urinal rinsing promotes the propagation of bacteria and viruses," said Liu's Xiangdong researcher in a press release. "The wearing of a mask should be mandatory in public toilets during the pandemic and anti-diffusion improvements are urgently needed to prevent the propagation of CVIV-19."

Using computer models, researchers discovered only five seconds after a urine is rinsing, the released virus particles can increase by two feet from the ground. (In June, some of the same researchers published the results of a simulation that found a hunting releases thousands of particles, some of which are projected one foot above the toilet bowl in about 30 seconds.)

"It is reasonable to assume that the high speed air flow will expel the aerosol particles from the bowl to the high-airborne areas above the toilets, allowing viruses to spread inside causing risks. For human health, "said researchers.

These particles can then fly over in the air, where they can be inhaled by the following people using the facilities and install on surfaces such as rinsing handles and handle handles.

Can Covid be widespread by aerosolization?

Although coronavirus has been isolated in feces and urine materials, it has been theory that the virus can spread through faecal-oral contact, the new study increases the eyebrows because it suggests that Covid-19 could also be transmitted by Virus particles in the urine.

Health officials said that Coronavirus spread primarily by contacts in person, for example, you are close to someone who has been infected with the virus and that they touch or sneeze, producing infectious respiratory droplets than you can inspire and be infected. These droplets are rather large and conventional wisdom is that they can travel about six feet before falling quickly on the floor.

The extent to which the virus is aerosolized - that is to say transmissible by smaller droplets that can linger in the air - is a subject that has attracted a lot attention in recent weeks. The World Health Organization said that "short-range aerosol transmission ... can not be excluded." Dr. Anthony Fauci, top expert on infectious disease of the nation, said: "I think there is certainly a degree of aerosolization," during an interview of August 3rd.AMERICAN MEDICAL ASSOCIATION JOURNAL. "But I'll take a step back and make sure we learn the facts before starting to talk about it."

Could he already happen?

Chinese researchers say that infection with aerosolization in a toilet has already arrived, highlighting a case of a husband and a woman who has contracted the virus in a public catering room in Beijing. "Two of Covid-19 Reamerging Confirmed cases in Beijing have been infected with a public toilet, which proves virtually the danger of public toilets," scientists said.
