Here are answers to five frequently asked questions about face coverings.
- Public health officials previously discouraged the public from wearing masks unless they were ill or caring for an ill person. Why the change?
There is some evidence indicating that a cloth fabric barrier can help reduce the spread of droplets from people who are infected but don't have any symptoms (asymptomatic). This new guidance is meant to help further reduce the spread of infections, along with physical distancing and bans on public gatherings.
- What is meant by a “face covering”?
According to CDPH, “A cloth face covering is a material that covers the nose and mouth. It can be secured to the head with ties or straps, or simply wrapped around the lower face.” It can be as simple as a bandana or scarf, or a factory-made or hand-sewn mask. Public health officials strongly discourage the use of hospital-grade and N95 masks, as these are needed by health care workers and are in short supply.
- When should people wear face coverings?
When leaving the home on an essential trip (grocery store, pharmacy, etc.) during which public contact is possible. There is no need to wear a face covering at home, unless someone in the home is at risk or showing symptoms of COVID-19.
- Does this mean we can go outside to public spaces?
No. This guidance should not be interpreted as a green light to leave quarantine for nonessential activities. The takeaway from Eric McDonald, medical director of San Diego County Epidemiology and Immunology, regarding the new guidelines is: “Stay in place. When you leave your place, cover your face.”
- What is the best way to care for face coverings and reduce the risk of viral transmission?
The face covering should be washed with soap and hot water between uses. If you need to remove your mask during the day, be sure to put it back on with the same side touching your face. Wash hands using proper hand hygiene after touching yourmask.
