Counties with highest COVID-19 infection rates in Maryland
The United States by April 21 had reached 569,404 deaths due to COVID-19 and more than 31.9 million cases, according to Johns Hopkins University. Amid the grim numbers come two bright spots: As of Feb. 2, more Americans had been vaccinated for COVID-19 than had been infected; and since then, rolling averages for case counts and deaths have been on the decline.
Stacker compiled a list of the counties with highest COVID-19 infection rates in Maryland using data from the U.S. Department of Health & Human Services. Counties are ranked by the highest infection rate per 100k residents from 4/13/2021 to 4/19/2021. Ties are broken by total new cases.
As has been true throughout America’s COVID-19 history, every state—and even every county—has its own COVID-19 story, driven by local policies and behaviors. Keep reading to see where infection rates are highest in your home state.
