Maximizing the fit of cloth and medical masks is key to improving performance and reducing SARS-CoV-2 transmission and exposure.But wearing two masks — or double masks — works too Help defend against the threat of more contagious variants.

Do I need to wear a double mask during the COVID-19 pandemic?

Dual masks are still a good idea in situations where you need to wear a mask.A laboratory study published in MMWR Masked and unmasked dummies were observed to release aerosol particles from their mouthpieces when simulating coughing or breathing. The study found that wearing a multi-layer cloth mask over a surgical mask or wearing a close-fitting surgical mask significantly improved the level of protection for mask wearers and others.

When dual masks are used, the CDC recommends wearing a comfortable cloth mask over the surgical mask. Surgical masks offer better filtration but tend to fit loosely. A cloth face covering fills in any gaps and provides another layer of protection. Surgical masks are also sometimes called medical masks or medical procedure masks.

Can masks help reduce the spread of COVID-19?

SARS-CoV-2 infection is primarily spread through respiratory droplets produced when people cough, sneeze, sing, talk or breathe. The CDC recommends community use of masks, especially non-valved multi-layer cloth masks, to prevent the spread of SARS-CoV-2. The main purpose of masks is to reduce the emission of virus-laden droplets (« source control »), which is especially important for asymptomatic or pre-symptomatic infected people who are feeling well but may not know they are infectious to others with more than 50% of transmission . Masks also help reduce the wearer’s inhalation of these droplets (« filtering to protect the individual »). The community benefit of masking for SARS-CoV-2 control is due to a combination of these effects; as more people continue to use masks correctly, the personal prevention benefit will also increase.

How do cloth face coverings and face coverings protect against COVID-19?

Cloth face coverings and face coverings are types of source control that provide a barrier between potentially infected individuals and droplets produced by others, reducing the likelihood of spreading the virus.

Can we reuse disposable surgical masks during COVID-19?

CDC does not recommend reusing single-use surgical masks intended for one-time use. FDA recognizes that surgical masks may have availability issues during the COVID-19 public health emergency, but there are strategies to preserve surgical masks.

Who can masks protect from COVID-19: the wearer, others, or both?

We’ve known for some time that masks help prevent people from spreading the coronavirus to others. Masks also protect the wearer themselves from infection, a new study argues, based on an analysis of available information.

Different masks block viral particles to varying degrees, the study authors wrote. If masks result in a reduced « dose » of the virus inhaled, fewer people may be infected, and those infected may be less ill.

Researchers in China used hamsters to test the effectiveness of masks. They placed healthy hamsters and hamsters infected with SARS-CoV-2 (COVID-19 coronavirus) in cages and used a barrier made of surgical masks to separate some healthy hamsters from infected hamsters. Many « masked » healthy hamsters were not infected, and those did get less sick than previously healthy « unmasked » hamsters.

When is it not appropriate to use a cloth face covering at work during the COVID-19 pandemic?

• If straps, cords, or other parts of the cover may be caught by the device.
• If other work hazards associated with wearing a face covering are identified and cannot be addressed without removing the face covering.

Cloth face coverings should not be worn if the new risks associated with their use (eg, interference with driving or vision, resulting in heat-related illness) outweigh the benefits of slowing the spread of the virus.
