The disease caused by the coronavirus, which scientists had already warned can be spread from fecal-oral transmission, can also be transmitted via “aerosolized feces,” according to Forbes, citing a study published by the Association for Professionals in Infection Control and Epidemiology.

Aerosolized feces can be propelled into the air through what’s called a toilet plume — the spread of aerosols, sometimes containing infectious fecal matter, caused by a flush.

“Close the lid and then flush,” a mechanical engineering professor from Purdue University, Dr. Qingyan Chen, told Forbes. He said it was a simple solution to help control the spread of the disease through toilet plumes.
