CDC recommends use of cloth face coverings, especially in areas of significant community-based transmission of COVID-19.
"Recent studies show that a significant portion of individuals with COVID-19 lack symptoms (“asymptomatic”) and that even those who eventually develop symptoms (“pre-symptomatic”) can transmit the virus to others before showing symptoms. In light of new evidence, CDC recommends wearing cloth face coverings to slow spread of COVID-19 in public settings where other social distancing measures are difficult to maintain (e.g., grocery stores and pharmacies) esp. in areas of significant community-based transmission," CDC says. "Maintaining 6-feet min. social distancing remains important to slowing spread of COVID-19. CDC also advises use of simple cloth face coverings to slow the spread of the virus and help people who may have the virus and do not know it from transmitting it to others. Cloth face coverings fashioned from household items or made at home from common materials at low cost can be used as an additional, voluntary public health measure to help slow the spread of COVID-19. The cloth face coverings recommended to slow spread of COVID-19 are not surgical masks or N-95 respirators. Those critical supplies must continue to be reserved for healthcare workers and other medical first responders, as recommended by current CDC guidance."
