COVID-19 has not hit each town equally — and different towns have borne the brunt of the virus at different times. 

State data releases on town-by-town case numbers are imperfect. They are delayed by a week and often represent such small increases in total case numbers that the Department of Public Health simply publishes them as "fewer than 5 additional cases."
