Face masks are touted as an important tool to prevent the spread of COVID-19 (new coronavirus infection), And new research provides more evidence that they work.

Researchers in Florida have found that face masks reduce the distance traveled by airborne pathogens such as coronaviruses by more than half.

“This study provides three clear evidences and guidelines. Feet Distance with face cover is better than 6 Feet Kareem Ahmed, co-author of the study, said he was an associate professor of mechanical and aerospace engineering at the University of Central Florida.

for study, Ahmed et al., Using special equipment, 14 people between the ages of 21 and 31 talk or cough when wearing different types of masks or not. We measured the distance between the droplet and the aerosol in all directions when it was coughing.

Each participant recites the phrase and cough 5 minutes without face cover, with cloth face cover and 3 layers of disposable surgical mask.

This study was on January 12th Infectious Disease Journal..

Learning more about how to reduce airborne infections keeps people safe and COVID-19 (new coronavirus infection) Other pandemics, according to researchers.

The next step is to expand the study with more participants.

The idea for this study came from a jet propulsion study conducted by the team.

“The principles are the same,” Ahmed said in a school news release. “our cough And the speech ran out of propulsion plumes. “
