COVID-19: Considerations for the use of masks |CDC less statistical sas

What you should know

Evidence for the effectiveness of masks

Your mask helps protect others

COVID-19 propagates mainly from person to person through respiratory droplets.Respiratory droplets travel through the air when coughing, sneezing, speaking, screaming or singing.These droplets can enter the mouth or nose of the people around it, who could also inhale them when breathing.

The masks are a simple barrier to help prevent their respiratory droplets from reaching other people.There are studies that show that masks reduce the dispersion of droplets when they cover the nose and mouth.

I should wear a mask, even if you don't feel sick.This is because multiple studies have shown that people with COVID-19 who never have symptoms (asymptomatic) and those that still do not have symptoms (presyd) can also spread the virus to other people.The use of mask helps protect those around you in case you are infected but not present symptoms.

The use of mask is especially important when it is in closed spaces with people with whom it does not live and when it is not possible to keep at least 6 feet away since the COVID-19 spreads mainly between people who have close contact with each other.

Your mask offers you a certain degree of protection

Fabric masks offer some degree of protection to you too.This level of protection against virus inhalation depends largely on the fabrics used and how its mask has been made (P.eg., the type of fabric, the amount of layers of fabric and how good the mask fits its face).CDCs are currently studying these factors.

Who should or should not wear a mask?

When to use masks:

CDC understand that there are certain specific instances in which the use of masks may not be possible.In such cases, consider using adaptations and alternatives.

The following categories of people are exempt from the requirement to use a mask:

Types of masks

Some masks are more effective than others to help slow the propagation of the virus caused by COVID-19.Note: N95 breathing masks approved by the National Institute for Occupational Health and Safety (NIOSH) of CDC should be prioritized for medical care personnel.
