The pace of new coronavirus cases in Pennsylvania continues to trend downward overall, but rates vary widely from county to county.
For a look at the most recent situation, here are the 10 counties with the highest per-capita rates of new infections in the past two weeks, according to data from the Pennsylvania Department of Health.
For each county, we list the number of new cases for the 14-day period of June 3 through 16, how that translates to a rate per 100,000 population, and whether the number of new COVID-19 cases is up or down compared to the prior two-week period (May 20 through June 2).
By comparison, the statewide rate was 51 new cases per 100,000 population in the past two weeks, and the number of new cases was down 29% compared with new cases in the previous two weeks.
