These are the ZIP codes with the most coronavirus cases in Maryland

Four of the top five ZIP codes in with positive coronavirus cases in Maryland are in the D.C.-area.

ANNAPOLIS, Md. — Maryland now has COVID-19 cases categorized by ZIP codes, which was provided by the state's health department on its coronavirus website

The five Maryland ZIP codes with the most coronavirus cases in the D.C. Metro area are:

  • 20904 (Colesville, White Oak, Fairland, Calverton in Montgomery County)
  • 20906 (Aspen Hill, Colesville, Leisure World in Montgomery County)
  • 20902 (Silver Spring, Kemp Mill, Wheaton-Glenmont, Wheaton, North Kensington, Glenview, in Montgomery County)
  • 20744 (Fort Washington, Oxon Hill, Camp Springs, Friendly in Prince George’s County)
  • 20706 (Lanham, Glenarden, Glenn Dale, Greenbelt, Mitchellville, Goddard, Westgate, Seabrook in Prince George's County). 

These ZIP codes are among the top six ZIP codes in the entire state with the most coronavirus cases, according to the Maryland Department of Health. Only the 21215 ZIP code in Baltimore has more coronavirus cases.  

But while this information in important and insightful, authorities are cautioning us to be careful drawing conclusions from new ZIP code maps that show where the highest numbers of coronavirus cases are turning up.

The same cautions were issued for county-by-county data showing death rates very high in some places and not others.

Dr. Travis Gayles, the chief health officer in Montgomery County, says answers are not straightforward. 

"It can be a little misleading," Gayles said. "All ZIP codes are not created equal in terms of how many folks live in those areas."

Gayles cautioned the ZIP code date is not adjusted for per capita rates of infection.

For example, some ZIP codes with high numbers also have high populations, while the actual rate of coronavirus per capita may be no worse than other, less populated ZIP codes, according to Gayles.
