Arlington has confirmed another 34 COVID-19 cases since Monday, the county’s second-largest increase in cases since the outbreak began.

There are now 237 known coronavirus cases in Arlington, up from 104 cases a week ago.

Statewide, the Virginia Dept. of Health is reporting 3,333 cases, 563 hospitalizations, 63 deaths and 28,645 people tested as of Tuesday.

As the numbers continue to increase, Arlington County is urging residents to follow the Centers of Disease Control and Prevention’s new guidance regarding wearing masks while in public.

Especially while in places like grocery stores and pharmacies, the county says, residents should wear a cloth facemask. Such masks can be made at home, as Arlington County Board Chair Libby Garvey demonstrated in a new video.

The county says masks — which are commonly worn in Asian countries, especially during flu season — are a way to prevent the spread of disease.

“The cloth face covering is to protect people around you if you are infected but do not have symptoms,” the county said. “To be clear, this is not meant as a replacement to staying at home, handwashing or maintaining six feet of distance — those remain the cornerstones in the effort to slow the spread of the coronavirus.”

There remains a stigma around wearing masks in public in the U.S., however. Just this morning, someone called Arlington County Police to report a “suspicious” man wearing a mask and supposedly pushing an empty baby stroller while looking into car windows. Arriving officers found that the man was a resident of the caller’s building and that there was a baby in the stroller

Virginia Gov. Ralph Northam is also pushing residents to wear masks, assuring those with concerns that a law that makes wearing masks in public in public a felony will not be enforced due to his declaration of a statewide emergency.
