A top infectious disease specialist has warned that wearing two masks “can cause more harm” if one of the face coverings is not being worn correctly.
Michael Osterholm, who was an advisor to President Joe Biden’s transition team, said the problem occurs with masks that have “already fitted or filtration capacity”, which allows respiratory droplets to exit the pores .
“If you add on another mask, you can actually make it harder for air to pass through the two-cloth area, and then at that point it actually causes more air around the sides, which Really enhances your ability to get infected., “Osterholm told NBC anchor Chuck Todd of” Meet the Press “on Sunday.
Osterholm stated that there are cases where double masking can be an effective tool against coronoviruses.
“But at the same time, there are many [where] You can do more harm, ”said the director of the Center for Infectious Disease Research and Policy at the University of Minnesota.
Osterholm said what is “very important” to him is to prevent people from wearing masks under his nose.
“You know, it’s like fixing three out of five screen doors in your submarine,” he said.
“We have got people to start using these rights, it will help a lot there,” he said.
White House Coronovirus Advisor Drs. Anthony Fauci has said that the two masks are “likely … more effective.”
