It is a new protocol with the purpose of saving lives.
Double masking may be the new normal for the next stretch of the pandemic, according to new data from the Centers for Disease Control and Prevention. In light of the emergence of new variants of COVID-19, this extra layer of protection can help to drastically prevent transmission, said Dr. Linda Yancey of Memorial Hermann to Chron.
“When asking people to wear a double mask, it doubles the protection you are receiving,” said Yancey. “It will be much more effective in preventing the spread of COVID-19. If you are already wearing an N95 mask, you probably won’t have many additional benefits.”

The researchers found that adding a cloth mask over a medical procedure mask could block up to 96.4 percent of the infection particles from escaping, ensuring a tighter fit and eliminating leaks, the CDC said. The practice of double masking substantially reduces the exhaled respiratory droplets and aerosols of those who are infected with COVID-19, according to the CDC.
“We continue to recommend that the masks should have two or more layers, completely cover the nose and mouth and fit comfortably on the nose and sides of the face,” said CDC director, Dr. Rochelle Walensky, in a briefing at the Casa White.
The CDC described five useful tips for making masks more protective.
-
The nose bridge wires ensure a tight seal.
- Mask devices can improve filtration by up to 90%.
- CDC’s “knot-and-fold” technique also reduces air leaks.
- Wearing a cloth mask over a surgical can block coughing particles.
- If in doubt, check for gaps by cupping your hands at the edges while inhaling and exhaling.
Folding your masks can potentially keep you safe from the threat of more infectious variants of COVID-19, emphasized Yancey. It also echoed the need for people to be safe at home during Houston’s winter storm, expected this weekend.
“We are currently in a race between the virus, its variants and the vaccine that is protecting people,” said Yancey. “This weekend, when it’s going to be terribly cold in Houston, it’s not time to go to a friend’s house. I take shelter on the spot with people from their family bubble.”
