Phase three reopening begins in Maryland at 5 p.m. Friday, bringing with it a return to some degree of normalcy just in time for Labor Day weekend.

For the first time since quarantine began, Marylanders will be able to go to the movies or attend an outdoor music concert. All businesses will be able to open, albeit with limited capacity depending on the type of venue.

Yet, as the state begins to open up, the data points to an increase in new COVID-19 cases, a worrisome trend that has led certain counties to delay entry into phase three.

Anne Arundel, Montgomery and Prince George's Counties chose to remain in phase two, citing the continued struggle with coronavirus in their regions.

In D.C., new research from Children’s National Hospital shows both the coronavirus and coronavirus antibodies can appear simultaneously in young patients. This means that children could be contagious even if antibodies are detected and they have no COVID-19 symptoms.

With this research in mind, the role children play in the spread of coronavirus could be underestimated. It's particularly important to note now as some students start their fall semester in-person.

What the Data Shows

Maryland reported 819 new COVID-19 cases Friday, the largest single-day increase in nearly a month, a concerning surge as the state moves into phase three.

The seven-day average of new cases is also trending upward, with Maryland now reporting an average of 595 daily cases, up from 538 just last week.

Nearly 400 people are currently hospitalized for COVID-19 in Maryland, safely below the state's hospital capacity.

Maryland's positivity rate is at 3.48%, up slightly from Thursday.

Greater Northern Virginia remains stable while coronavirus cases continue their week-long rise elsewhere in the state. The seven-day average for cases in Virginia, excluding Greater NoVa, has increased from 659 to 742 over the past week.

In D.C., the seven-day average of new cases has fallen slightly, down 7 cases from last week.

D.C. continues to maintain good coronavirus metrics, although only 7.5% of new COVID-19 cases are coming from quarantined individuals, far below the city's goal of 60%.

New cases in Virginia are also increasing. Virginia is now averaging 973 new cases daily, compared to 896 a week prior.

Virginia's positivity rate is still high. Out of all Virginians tested, 7.8% are coming back with positive test results.

How to Stay Safe

There are ways to lower your risk of catching coronavirus. Here are guidelines from the CDC:

  • Wear a snug-fitting mask that covers your nose and mouth. 
  • Avoid being indoors with people who are not members of your household. The more people you are in contact with, the more likely you are to be exposed to COVID-19. If you are indoors with people you don’t live with, stay at least six feet apart and keep your mask on. 
  • Wash your hands often, especially after you have been in a public place.
