Of the 32 tested by the National Institute of Standards and Technology, three of the five most effective cloth face coverings were 100% cotton and had a visible raised fiber or nap, such as found on flannels. In its announcement this week the agency noted the five lowest performers were synthetic materials. The Centers for Disease Control and Prevention recommends people wear cloth face coverings to help protect others in public settings where social distancing is difficult. In addition, many of Arizona’s cities, towns and counties have implemented mandates requiring the use of face masks when in public settings. AzHHA is committed to the message to Mask Up in Arizona. We do it to help stop the spread of COVID-19 and for the protection of our healthcare workforce.
