Experts want us to “put a lid on” the spread of COVID-19 — the toilet lid.

That action is highly recommended after researchers discovered that the deadly virus can travel in fecal matter that escapes into the air. They call it “aerosolized feces,” and it is propelled into the air through a toilet plume that gets shot upwards after a flush.

According to the New York Post, a study conducted by the Association for Professionals in Infection Control and Epidemiology discovered this dangerous transmission and recently published their results.

“Close the lid and then flush,” advises Dr. Qingyan Chen, a mechanical engineering professor from Purdue University. Chen said that closing the lid can prevent 80% of the fecal particles from escaping into the air.

According to Bustle.com, researchers at Leeds University in 2012 found that germs can be hurled up to 10 inches into the air every times a toilet is flushed without closing the lid.
