Health expert weighs in on different face masks
The Centers for Disease Control and Prevention (CDC) is mulling a significant change in their COVID-19 face mask guidelines.
Health officials say masks like the KN95 or N95 work best against the omicron variant of the coronavirus because of their four layers of protection.
"Omicron is an airborne virus, it stays in the air for twenty minutes," said Dr. Sujan Gogu with South Texas Health System. "So just imagine, you can just go through any type of door or any type of room and you've had individuals who have been there--that virus is still there airborne. So, it's very important to have a good fitted N95 or KN95 mask."
Surgical masks have three layers of protection and cloth masks offer two layers of protection.
"If air is leaving this mask, then I know that there's particles that are potentially leaving," said Dr. Gogu. "Or there's opportunity for particles to come in to infect me."
Gogu says it's essential to adjust the mask around the nose and fit the face.
The CDC recommends reusing a mask no more than five times. Dr. Gogu also recommends alternating between three masks.
"It gives the other two masks time for any virus particles that are there to just die because the virus only lasts for so long on a surface," Dr. Gogu said.
