Flushing a toilet can generate droplets containing virus. FLORIDA ATLANTIC UNIVERSITY
After you’ve flushed a public toilet, don’t linger (逗留)! Tiny droplets (液滴) containing small pieces of urine (尿), feces (粪便), vomit and viruses float into the air at mouth-level after a toilet is flushed, a study published in the journal Physics of Fluids in March finds. It shows that tens of thousands of droplets are sprayed into the air by a flush and can rise about 1.5 meters above the ground. Researchers say the droplets could be virus carriers. If a passerby breathes in the droplets that carry virus, they could be infected.
