The Centers for Disease Control and Prevention has warned that the coronavirus will likely spread in the United States and is preparing for a possible pandemic.
The announcement has stoked fear in many people over getting the virus, which was first identified in China, and causes the respiratory illness COVID-19. Because the virus is new to us and there’s a lot of scary news around it, many have started wearing face masks to protect themselves, as the virus is transmissible through human contact and exposure to respiratory droplets from an infected person.
Experts are somewhat skeptical about how effective they are in protecting people against dangerous viruses and bacteria. Below is their take on whether or not you should wear a mask and how else you can protect yourself.
When an infected person coughs or sneezes, they expel respiratory droplets into the air that carry the virus. They can also spread those droplets around if they touch their eyes and nose then touch another person or surface. If someone were to come into contact with these contagious droplets either in the air or by touching a surface that contained the droplets they, too, could get sick.
There is some evidence that, when used correctly, face masks can slow the spread of airborne viruses. For example, one study from 2008 found that those who used a mask were 80 percents less likely to get the flu. Another 2009 report found that, in tandem with frequent hand-washing, face masks lowered people’s risk of getting the flu by about 70percents .
“Masks of any kind would be helpful because then they are covering up your nose and mouth so they aren’t going to touch those, but they still leave your eyes open so you can touch and transmit the virus that way,” Michael Ison, an infectious disease specialist with Northwestern Medicine, told HuffPost.
When we look back at the severe acute respiratory syndrome epidemic that struck in 2003, researchers concluded that face masks played some role in slowing down the spread especially in a hospital setting but mostly because they prevented sick people from passing SARS around. In fact, most people in Asia wear the masks not to avoid getting sick themselves but to protect other people from harmful germs and viruses.
In 2012, when another deadly coronavirus Middle East respiratory syndrome MERS struck, health officials recommended wearing a face mask only if you were in the same room as a person with MERS. There just wasn’t enough evidence on if masks had any role in halting the spread of MERS.
The main takeaway here: Masks alone won’t eliminate your risk of contracting the coronavirus. But, they may help.
“It can reduce the risk of some transmissions, but doesn’t take the risk to zero,” Ison said.
There are two types of face masks that can help cut your odds of getting coronavirus: Surgical face masks and respirators, also known as (N-95) masks.
The ones we’re seeing all over the news? Those are surgical face masks, and what doctors, dentists and nurses use while treating patients.
While they do protect people from splashes and sprays to a degree, they aren’t foolproof. They’re loose fitting and relatively thin, so tinier droplets can still seep in through the parts of the mask.
“Surgical masks do provide a degree of protection against fluids, including spray from a cough or sneeze, and they provide some filtration of the air. However, since the masks do not provide a tight seal around the wearer’s nose and mouth, much of the air inhaled and exhaled is unfiltered,” said Richard Martinello, a Yale Medicine infectious disease specialist.
But, they aren’t so comfortable and many people report trouble breathing while wearing them, making them difficult to wear for hours on end. Respirators can get clogged and cause people’s breathing and heart rate to soar, so pregnant people or individuals with breathing problems should consult a doctor before using one.
Health experts still say you don’t need to panic. While the CDC is preparing for the spread of the virus here in the U.S., the immediate risk for people is still relatively low and experts stress that it’s important to stay calm.
How well the masks work largely depends on if you’re is wearing it correctly. Make sure the correct side is facing outward, keep the mask snug over your nose, secure the loops behind your ears, and close off the gaps around your jawline.
There are other steps that are more effective than wearing a mask. For one, keep a distance from sick people, especially those coughing or sneezing. Also, not touching your face with your hands minimizes your exposure to harmful germs.
Lastly, hand-washing is your best line of defense against any virus, so wash frequently and thoroughly. That means spending at least 20 seconds scrubbing your hands with soap and rinsing water.
