The Covid-19 Coronavirus: Should you Wear a Face Mask

Must read

The face mask industry is booming amid concerns about the coronavirus outbreak in China and throughout the world. The nation’s largest surgical mask manufacturer is struggling to keep pace with skyrocketing demand.

The Associated Press reports that some countries like Thailand have placed price ceilings on face masks to fight price gouging.

But the Centers for Disease Control and Prevention in the United States says it “does not recommend that people who are well wear a face mask to protect themselves from respiratory diseases. Including the COVID-19 coronavirus that’s spreading worldwide.”

“Face masks should be used by people who show symptoms of COVID-19 coronavirus to help prevent the spread of the disease to others,” the CDC’s website says. “The use of face masks is also crucial for health workers and people who are taking care of someone in close settings (at home or in a health care facility).”

Dr. Frank Esper, a pediatric infectious disease specialist at the Cleveland Clinic, explained the circumstances when some really sick people should wear a face mask.

“If they are coughing, if they are feeling like they have symptoms, we do ask them to put on a face mask. Above all when they are coming to our waiting room or ER or into a public space,” he said. “It helps prevent the spread of infection.”

Can face masks protect against the new coronavirus infection?

Esper and other experts say washing your hands frequently is the best way to prevent the spread of infectious illnesses like coronavirus or, more commonly, the flu. The CDC advises washing your hands often with soap and water for at least 20 seconds, or use an alcohol-based hand sanitizer that contains at least 60% alcohol if soap and water are not available.

You should also avoid touching your eyes, nose and mouth with unwashed hands, avoid contact with sick people, cover your mouth when you cough and sneeze, and disinfect objects and surfaces frequently, the CDC told CBS.

Pictures taken around the world show some people wearing surgical face masks in public while others appear to be wearing respirators, which the CDC says are used to reduce a wearer’s risk of inhaling hazardous airborne particles, gases or vapors.

The CDC says it “does not recommend the routine use of respirators outside of workplace settings (in the community). Most often, spread of respiratory viruses from person-to-person happens among close contacts (within 6 feet). CDC recommends everyday preventive actions to prevent the spread of respiratory viruses, such as avoiding people who are sick, avoiding touching your eyes or nose, and covering your cough or sneeze with a tissue.”

What about N95 face masks

P2 respirator masks (comparable to N95 masks) and surgical masks.

Health and Human Services Secretary Alex Azar addressed the issue of different kinds of masks on Wednesday before a House Appropriations subcommittee. He was asked about N95 masks, which are respirators that the CDC says filter out at least 95% of airborne particles. These masks require proper fitting and training to work effectively, and officials do not recommend that the public use them.

Azar said people mistakenly have a sense that “the mask” is the “be all, end all of either preparedness or response activities.”

“It’s an element in our armamentarium, mostly for health care workers,” he said. “And that’s that N95 mask that’s actually fitted. It has to be carefully fitted, and it can protect the worker.”

Disposable surgical masks also are not recommended

Azar said wearing masks “could actually sometimes be more harmful to you than not wearing a mask, because if it’s not fitted right you’re going to fumble with it. You’re going to be touching your face, which is the No. 1 way you’re going to get disease, is unclean hands touching your face.”

“Basic public health hygiene — washing hands, and extended time for soap and water, not touching your face, coughing into your elbow — these are the best things for flu season, for common cold, for novel coronavirus that any of us can do for preparedness,” he said.

So far, the new coronavirus has sickened tens of thousands of people around the world. Most cases have been in China, but it has spread to other countries, too, and South Korea, Italy and Iran have reported significant daily jumps in cases.
