Wearing two masks reduces chances of catching Covid-19 by 95 percent: Study Finds

Health experts in the United States have asked people to wear not just one but two masks to safeguard themselves against coronavirus.

According to a recent study published by the Centers for Disease Control and Prevention in the United States, wearing two masks exponentially decreases a person’s chances of catching Covid-19.

The CDC’s report comes a year into the pandemic, is the first such report specifically looking at the use of face mask-wearing techniques and its importance in prevention.




According to CDC’s findings, wearing two masks reduces the chances of persons exchanging viral particles between them by 95 percent. This is more than twice the chances that wearing one mask provides, which is 42-44 percent.

Scientists agree the main way the virus is spread is through the air, rather than surfaces, and there’s growing evidence that small droplets from breathing and speech that can travel many meters are a common mode of transmission.

Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases in US also called wearing two masks “common sense” as wearing two layers of protection would be more effective than wearing just one.



Scientists have prescribed wearing a cloth mark on top of a surgical mask to provide the fullest protection. Doctors have also stressed knotting and tucking their masks to ensure a higher degree of blocking.
