Recent Trends

The top chart shows that the weekly number of new cases per 100,000 people in Evanston, suburban Cook County, Chicago, and the State are each at or below 12.  

The lower chart shows that the test-positivity rates in each region are at or below 0.8%.  The low rates indicate that the amount of testing in each region is adequate.

The number of people in the State being vaccinated continues to grow, but at a very slow pace. As of June 23, 62.15% of Illinois residents 12 and older had at least one dose of a vaccine; 54.09% were fully vaccinated.

As of June 24, according to the City of Evanston, 82.3% of Evanston residents 12 and older had received at least one dose of a vaccine; 72.4% were fully vaccinated.

Evanston – COVID

Evanston reported no new COVID-19 cases of Evanston residents today.  

The average number of new cases per day in the last seven days is 0.4. There has been a total of 1,682 tests administered to Evanston residents in the last seven days.

There has been a total of 4,653 COVID-19 cases of Evanston residents during the pandemic, three of which are active. 

No Evanstonian has died due from COVID-19 since May 31. The number of deaths due to COVID-19 is 118.

Impact of Northwestern University. Northwestern University has posted data on its website reporting that between June 11 and June 17, there was one new confirmed COVID-19 case of an NU faculty member, staff member or student. If the faculty member, staff member or student resides in Evanston, the case would be included in the City’s numbers.  


1/ The State moved to Phase 5 of the Restore Illinois Plan on June 11. Going forward, the RoundTable plans to cover COVID-19 metrics on a more limited basis. Specifically, we plan to provide charts showing: 1) the trends in the number of new COVID-19 cases per 100,000 people in two recent seven-day periods for Evanston, Chicago, Suburban Cook County. The chart also shows the weekly numbers of new cases for each region as of  June 10 as a baseline to guage whether cases are going up since the move to Phase 5; and, 2) the most recent test positivity rates for these areas.   

As discussed in footnote 2 below, the CDC recommends that these two measures be used to determine the level of risk of transmission.  If we see a surge in new cases or in the test positivity rates, we will consider covering additional metrics.

We will also report the most recent percentages of vaccinated people, 12 years and older, in Evanston and Illinois.

2/ On Feb. 12, the CDC issued a K-12 School Operational Strategy. As part of that strategy, the report says CDC recommends the use of two measures to determine the level of risk of transmission: 1) the total number of new cases per 100,000 persons in the past 7 days; and 2) the percentage of COVID tests during the last seven days that were positive. The CDC provides a chart to assess whether the risk of transmission is low, moderate, substantial, or high. If the two indicators suggest different levels of risk, CDC says the higher level of risk should be used. The table below, reprinted from CDC’s report, provides CDC’s Indicators and Thresholds for Community Transmission of COVID-219.
