Flushing urinals involves an interaction between gas and liquid interfaces, releasing large-scale aerosol from the urinals that spread the virus.
The researchers revealed that the trajectory of the tiny particles emitted by flushing a urinal manifests an external spread type, with more than fifty-seven percent of the particles traveling away from the urinal. In their earlier studies, scientists from Yangzhou University, China, had shown that both feces- and urine-based COVID-19 transmission is possible. So the researcher's advice to wear a mask while using a public toilet. COVID-19 can also be transmitted through the oral-fecal route by infecting intestines. Reports from Emerging Microbes and Infection provides a cautionary warning that COVID-19 maybe shed through multiple pathways.
