The number of residents either confirmed or probable for contracting COVID-19 fell sharply week over week in both Riverside and North Riverside as of the morning of April 20, according to the Cook County Department of Public Health.
That same drop was not seen in Brookfield, however, where the number of people either confirmed or probable for new cases of COVID-19 remained at levels last seen in January.
After four straight weeks of increased new cases, Riverside saw just six new cases during the week-long period ending on the morning of April 20. The prior week’s total of 20 had been the village’s highest since late January, with last week’s totals in line with what the village saw throughout March.
Likewise, after seeing the number of new cases spike to 13 the week prior, in North Riverside just five new cases were reported for the week ending on the morning of April 20, roughly in line with where the number of new cases had been through March and the beginning of April.
There were no new fatal cases of COVID-19 reported in either Riverside or North Riverside in the past week, and the seven-day rolling positivity rate for the 60546 ZIP code, which includes both Riverside and North Riverside, fell again below 3 percent after spiking to about 6 percent a week earlier.
As of April 18, the most recent date listed on the Northwestern University School of Medicine’s online dashboard tracking COVID-19 data, the seven-day rolling positivity rate in the 60546 ZIP code was 2.01 percent.
In Brookfield, where the number of new COVID-19 cases has risen in six of the past seven weeks, there were 48 new cases reported during the week-long period ending on the morning of April 20, one more than the prior week and the highest number since the week ending Jan. 19.
While it took more than five weeks for the total number of cases in Brookfield to go from 1,600 to 1,700, Brookfield is on track to blow past 1,800 cases less than three weeks later.
As of the morning of April 20, the village had reported 1,785 total cases with 13 fatalities. There were no new fatal cases of COVID-19 reported in the past week.
But, the village’s positivity rate continues to be high, with the seven-day rolling rate as of April 18 reported at 8.32 percent, just a shade lower than the 14-day rate of 8.62 percent.
