Data suggests that many who are infected with COVID-19 are not symptomatic. For that reason, the New Orleans Health Department is recommending members of the public wear cloth face coverings when doing essential activities, such as grocery shopping. It is especially important for essential workers, like grocery or bank clerks, to wear face coverings as they are coming into contact with many people throughout the day.
At this time, you should not be purchasing medical grade masks, which are in short supply. It is extremely important that surgical and N95 masks are reserved for those who need them most and have the highest risk of infection, like medical professionals and healthcare workers.
Face coverings are a minimal level of protection. It is still imperative that you stay home except for essential needs and always avoid close contact with others.
The New Orleans Health Department and the CDC now recommend that Americans wear cloth face coverings in public, when doing essential activities.
