Maryland Cases by County
To keep these charts clean, I established a threshold of 50 confirmed cases to be separately listed in this chart. On 4/1/2020, Dorchester county reported its first confirmed case. On 4/2/2020, Allegany, the last to fall, reported its first case. On 4/5/2020 Harford crossed the 50 confirmed case threshold.
