Covid-19: How Much Protection does the Mask Provide?

Sep. 27, 2020

Can masks help slow the spread of the coronavirus (SARS-CoV-2) that causes COVID-19? Yes, masks combined with other preventive measures (such as frequent hand washing and staying away from society) can help slow the spread of the virus.

So why is it not recommended to wear a mask at the beginning of the pandemic? At the time, experts did not know the extent to which people infected with COVID-19 could spread the virus before symptoms appeared. It is also not known that some people have COVID-19 but do not have any symptoms. Both groups may unknowingly spread the virus to other people.

These findings prompted public health organizations to make a face on the mask. The World Health Organization and the US Centers for Disease Control and Prevention now include masks in their recommendations to slow the spread of the virus. The CDC recommends that citizens cloth masks instead of requiring surgery and N95 masks by health care providers.

How do different types of masks work?

Face mask

Surgical masks, also called medical masks, are loose disposable masks that protect the wearer's nose and mouth from water droplets, splashes and sprays that may contain germs. Surgical masks can also filter out large particles in the air. Surgical masks can protect others by reducing exposure to saliva and respiratory secretions of mask wearers.

At present, the US Food and Drug Administration has not approved any type of surgical masks specifically for the prevention of coronavirus, but when there is no N95 mask, these masks may provide some protection.

N95 mask

The N95 mask is actually a respirator that provides more protection than disposable face mask china, because it can filter out large and small particles when the wearer inhales it. As the name suggests, the mask is designed to block 95% of very small particles. Some N95 masks have valves to make them easier to breathe. With this mask, unfiltered air is released when the wearer exhales.

Before using N95 gas masks in the workplace, healthcare providers must be trained and passed appropriate tests to confirm proper sealing. Like surgical masks, N95 masks should also be disposable. However, researchers are testing methods to disinfect N95 masks so that they can be reused.

Some N95 masks, and even some cloth masks, have one-way valves to make them easier to breathe. But because the valve releases unfiltered air when the wearer exhales, this mask does not prevent the wearer from spreading the virus. Therefore, their use is prohibited in some places.

Cloth mask

The gas mask is designed to capture the water droplets released when the wearer speaks, coughs or sneezes. Requiring everyone to wear a mask can help reduce the spread of the virus to people who have COVID-19 but are not aware of it.

When cloth face masks are widely used by people in public places, it is most likely to reduce the spread of the COVID-19 virus. Countries that needed masks in the early stages of a pandemic, testing, isolation, and distancing from society have successfully slowed the spread of the virus.

Although surgical masks and N95 masks may be in short supply and should be reserved for medical staff, cloth face masks and masks are easy to find or manufacture, and can be washed and reused.

The mask can be made of ordinary materials, such as a sheet made of tightly woven cotton. The instructions are easy to find online. Cloth masks should include multiple layers of fabric.
