COVID-19: Why Wearing a Mask Matters

Published on Feb. 10, 2021

Wearing masks

If you have been out and about in northern Michigan lately, you’ve likely seen the signs at grocery stores, restaurants, gas stations, and other businesses: “Mask required.”

Waddles Supports Wearing a MaskThis requirement went into effect on April 26 with Gov. Whitmer’s Executive Order 2020-59, which states: Any individual able to medically tolerate a face covering must wear a covering over his or her nose and mouth—such as a homemade mask, scarf, bandana, or handkerchief—when in any enclosed public space.

There’s been a lot of confusion over mask wearing. At first it wasn’t recommended, then it was. It leaves many of us asking, do masks really prevent the spread of COVID-19?

The short answer: Yes. The new coronavirus spreads mainly from person to person through respiratory droplets produced when an infected person coughs, sneezes, or talks. Face masks help prevent the spread of the virus by keeping droplets out of the air and off of surfaces.

Early on in the pandemic, public health officials said the general public didn’t need masks, but as the science surrounding COVID-19 evolved, it soon became clear that infected people can spread the coronavirus before they show symptoms or even if they never show symptoms (called asymptomatic spread).

In response to many new scientific studies, the World Health Organization recently released the following guidance: “WHO advises that governments should encourage the general public to wear masks where there is widespread transmission and physical distancing is difficult, such as on public transport, in shops or in other confined or crowded environments."

Whether or not you are feeling sick or have COVID-19 symptoms, there is evidence that if you have the virus, you may be able to transmit it to others when you speak, cough, or sneeze. In short, wearing a mask protects the people around you. If everyone combines wearing a mask while in public with social distancing, the risk of community spread can be reduced.

What Type of Mask Should I Wear?

You’ve probably seen the most common types of masks: N95 masks, surgical masks, and cloth masks.

N95 Respirator Masks

N95 respirator masks are tight fitting and made of material that can filter out an estimated 95% of airborne particles. This type of mask should only be used by frontline healthcare and other workers who need them as part of their job to perform specific high-risk procedures for patients. It is not recommended that the general public wear N95 respirators to protect themselves.

Surgical/Medical Masks

Surgical masks should be worn by healthcare workers, people with COVID-19 symptoms, or anyone taking care of someone suspected or confirmed with COVID-19, but they are becoming more widely available for general use. Typically, these disposable, single-use masks are rectangular with pleats to expand to cover your nose, mouth, and jawline, and are made of breathable synthetic fabric.

Cloth Masks

Most of the general public should wear a cloth mask when out and about in crowded spaces where social distancing cannot be practiced, such as at the grocery store. Cloth masks can be made from a variety of materials, including cut fabric, bandanas, pillowcases, or T-shirts.

In addition to wearing a mask, follow these everyday healthy habits:

  • Stay at least 6 feet away from others
  • Avoid contact with people who are sick
  • Avoid touching your nose, eyes, and mouth
  • Wash your hands often with soap and water, for at least 20 seconds each time
