Washington County has been one of the Maine counties least affected by the coronavirus since the pandemic hit in March. It’s often gone weeks without recording new infections, and has maintained one of the lowest numbers of COVID-19 cases in the state. But cases in the county of 31,000 have more than doubled in the past week, to 48 on Monday from 21 a week earlier, and Washington County is seeing its rates of new daily cases and active infections exceed the statewide rates.
