After seeing its number of new COVID-19 cases fall for three straight weeks from mid-April into early May, Brookfield has seen its new case numbers increase for two consecutive weeks.

For the week-long period ending on the morning of May 25, there were 25 new COVID-19 cases reported in Brookfield, up from 23 the prior week. That pushed the village’s total number of cases since the pandemic began to 1,907, which represents about 10 percent of the village’s total population.

Brookfield’s rolling seven-day positivity rate also rose to 5.71 percent as of May 24, the most recent data available from Northwestern University School of Medicine’s online COVID-19 dashboard.

That compares unfavorably to the positivity rate seen across the state of Illinois, where as of May 21 it was 3.6 percent, and the rest of suburban Cook County, where it was 3 percent as of May 21, according to the Illinois Department of Public Health.

The 60546 ZIP code, which includes both Riverside and North Riverside saw its rolling positivity rate rise slightly to 3.28 percent as of May 24, but Riverside itself saw its number of cases rise for the second straight week as well. 

Riverside recorded 15 new COVID-19 cases in the past week as of the morning of May 25, its highest one-week total since early April. The prior week the village saw nine new cases. In all, 966 people in Riverside have contracted COVID-19 since the pandemic began last year, according to the Cook County Department of Public Health, also roughly 10 percent of its population.

North Riverside for the second straight week held steady at eight new cases, with 605 having contracted COVID-19 in total since March 2020. 

Local vaccination rates continue to rise steadily, though North Riverside continues to lag behind both Riverside and Brookfield.

In North Riverside, just 30.4 percent of the population had been completely vaccinated as of the morning of May 25, according to the Cook County Department of Public Health.

By contrast, Riverside residents have been fully vaccinated at more than twice that rate, with 65.3 percent fully vaccinated. In Brookfield, 46.2 percent of residents are fully vaccinated.

The disparity is even greater when it comes to the percentage of residents who have received at least one dose of the COVID-19vaccine. In Riverside, 82.7 percent of residents have had at least one shot, while 58.1 percent of Brookfielders have had at least one dose of the vaccine.

Just 37.6 percent of North Riverside residents have had at least one dose by comparison. 

The village lags behind the state and county vaccination rates as well. According to the IDPH, 39.92 percent of all Illinoisans were fully vaccinated as of May 24. In Cook County, that figure was 42.58 percent.
