A mask is NOT a substitute for social distancing. Masks should still be worn in addition to staying at least 6 feet apart.
Am I considered a close contact for COVID-19 if I was wearing a mask?
The smallest very fine droplets, and aerosol particles formed when these fine droplets rapidly dry, are small enough that they can remain suspended in the air for minutes to hours.
What is considered a close contact of someone with COVID-19?
For COVID-19, a close contact is anyone who was within 6 feet of an infected person for a total of 15 minutes or more over a 24-hour period (for example, three individual 5-minute exposures for a total of 15 minutes).
Should one wear a surgical mask?
For COVID-19, a close contact is anyone who was within 6 feet of an infected person for a total of 15 minutes or more over a 24-hour period (for example, three individual 5-minute exposures for a total of 15 minutes).
Can face coverings reduce the risk of COVID-19?
A study of an outbreak aboard the USS Theodore Roosevelt, an environment notable for congregate living quarters and close working environments, found that use of face coverings on-board was associated with a 70% reduced risk.
Who do masks protect from COVID-19: the wearer, others, or both?

How can surgical masks protect me from COVID-19?
If worn properly, a surgical mask is meant to help block large-particle droplets, splashes, sprays, or splatter that may contain germs (viruses and bacteria), keeping it from reaching your mouth and nose. Surgical masks may also help reduce exposure of your saliva and respiratory secretions to others.
What should you do if you have been around a person with COVID-19?
If worn properly, a surgical mask is meant to help block large-particle droplets, splashes, sprays, or splatter that may contain germs (viruses and bacteria), keeping it from reaching your mouth and nose. Surgical masks may also help reduce exposure of your saliva and respiratory secretions to others.
Should I be tested if I have been in close contact with someone who has COVID-19?
If worn properly, a surgical mask is meant to help block large-particle droplets, splashes, sprays, or splatter that may contain germs (viruses and bacteria), keeping it from reaching your mouth and nose. Surgical masks may also help reduce exposure of your saliva and respiratory secretions to others.
How long does it take for symptoms of COVID-19 to appear after exposure?
Symptoms may appear 2 to 14 days after exposure to the virus.

What kind of mask should I wear during the COVID-19 pandemic?
People must wear masks that completely cover the mouth and nose. Masks should fit snugly against the sides of the face. See CDC’s guidance for attributes of masks needed to fulfill the requirements of the Order.
Should I use a surgical masks or N95 respirators to protect against COVID-19?
No. Surgical masks and N95s need to be reserved for use by health care workers, first responders, and other frontline workers whose jobs put them at much greater risk of acquiring COVID-19. The cloth face coverings recommended by CDC are not surgical masks or N95 respirators. Surgical masks and N95s are critical supplies that must continue to be reserved for health care workers and other medical first responders, as recommended by CDC.
What types of masks are most and least effective at preventing the spread of COVID-19?
No. Surgical masks and N95s need to be reserved for use by health care workers, first responders, and other frontline workers whose jobs put them at much greater risk of acquiring COVID-19. The cloth face coverings recommended by CDC are not surgical masks or N95 respirators. Surgical masks and N95s are critical supplies that must continue to be reserved for health care workers and other medical first responders, as recommended by CDC.
How do cloth face coverings and face shields protect against COVID-19?
Cloth face coverings and face shields are types of source control that provide a barrier between droplets produced from a potentially infected person and other people, reducing the likelihood of transmitting the virus.
Does wearing a cloth mask over a medical one reduce exposure to COVID-19 more than wearing just one mask?
Based on experiments that measured the filtration efficiencies of various cloth masks and a medical procedure mask (6), it was estimated that the better fit achieved by combining these two mask types, specifically a cloth mask over a medical procedure mask, could reduce a wearer’s exposure by >,90%.
Why is it recommended to wear a mask during COVID-19?
SARS-CoV-2 infection is transmitted predominately by respiratory droplets generated when people cough, sneeze, sing, talk, or breathe. CDC recommends community use of masks, specifically non-valved multi-layer cloth masks, to prevent transmission of SARS-CoV-2. Masks are primarily intended to reduce the emission of virus-laden droplets (“source control”), which is especially relevant for asymptomatic or presymptomatic infected wearers who feel well and may be unaware of their infectiousness to others, and who are estimated to account for more than 50% of transmissions.1,2 Masks also help reduce inhalation of these droplets by the wearer (“filtration for personal protection”). The community benefit of masking for SARS-CoV-2 control is due to the combination of these effects, individual prevention benefit increases with increasing numbers of people using masks consistently and correctly.
