  • The numbers on this map reflect Carroll County cases only, so will not be the same as the Maryland Department of Health map in zip codes that are in more than one county. The data includes both community and facility cases.
  • Data is suppressed in zip code areas with 7 or fewer cases.
  • Case numbers represent confirmed cases of COVID-19 and do not reflect the risk of contracting the disease in those areas; the coronavirus is spreading throughout the community and residents should continue to follow social distancing guidelines no matter where they are in the county.
