On Track to Phase 5
The State is still on target to move to Phase 5 of Illinois’ Reopening Plan on June 11. When the State moves to Phase 5, normal business operations may resume, free of pandemic related mitigations.
The criteria to move to Phase 5 of the Reopening Plan and the status of meeting the criteria are as follows:
- 70% of the population 65 and older must have received at least one dose of a vaccine. This has been met. More than 82% of this age group has had at least one dose of a vaccine.
- 50% of the population 16 and older must have received at least one dose of a vaccine. This has also been met. More than 60% of this age group has had at least one dose.
- The trend of hospital admissions for a COVID-19 like illness must not be increasing in the last 28 days. As of today, the trend is “decreasing.”
- The trend in the number of COVID-19 patients in the hospital must not be increasing. As of today, the trend is “decreasing.”
- ICU bed availability must remain greater than or equal to 20% over the most recent 28 days. As of today, there is 23% availability.
The Illinois Department of Public Health also said today the trend of new COVID-19 cases is “decreasing” and there is no “significant” change in the number of deaths due to COVID-19 in the last 28 days.
If the trends hold, businesses in Illinois may return to the new normal on June 11.
Risk of Community Spread
The charts in the above chart box show that the seven-day averages of new cases in Evanston, suburban Cook County, Chicago, and the State are continuing to decline.
The seven-day average of new cases for the State is the lowest it has been since last July 24. Evanston had no new cases today, and its seven-day average of new cases per day has dropped to 1.7. Its test positivity rate is still 0.2%.
For benchmarks used to assess the risk of spread, see footnotes 1–4.
Evanston – COVID
The City reported one new COVID-19 case of an Evanston resident today, compared to none yesterday.
The average number of new cases per day in the last seven days is 1.7, down from the seven-day average of 3.4 on May 21.
In the last seven days, there was a total of 12 new COVID-19 cases of Evanstonians, which equates to about 16 new cases per 100,000 people in the seven-day period.
Evanston’s case positivity rate for the last seven days is 0.2%.
There has been a total of 4,635 COVID-19 cases of Evanston residents during the pandemic, 68 of which are active.
No Evanstonian has died from COVID-19 since May 6. The number of deaths due to COVID-19 is 117.
Impact of Northwestern University. Northwestern University has posted data on its website reporting that between May 21 and May 27, there were no new confirmed COVID-19 case of an NU faculty member, staff, or student. (If the faculty member, staff or student resides in Evanston, that case would be included in the City’s numbers. The numbers reported by NU, though, include people who live outside of Evanston.) 
Illinois – COVID-19
In the State, there were 982 new COVID-19 cases reported today, up from 891 yesterday.
Statewide, the average number of new cases per day in the last seven days is 972, which is the lowest seven-day average this year. The seven-day average one week ago on May 21 was 1,421, so today’s number is down by 32%. The downward trend continues. An accompanying chart shows the trend.
In the seven days ending May 28, the number of new cases per 100,000 people in the State was 54, down from 79 one week ago.
The seven-day case positivity rate for the State today is 1.9% and the test positivity rate is 2.3%.
On a Statewide basis, the number of hospitalizations due to COVID-19 was 1,216 as of midnight on May 27. The number is up from 1,112 on March 15.
IDPH said today that the trends in new hospital admissions and total patients hospitalized due to COVID-19 has been “decreasing” in the last 28 days.
The number of patients using ICU beds is 314, up from 227 on March 15. The number of patients on ventilators is 172, up from 95 on March 15.
On a Statewide basis, there were 21 deaths due to COVID-19 in the last 24 hours, which brings the total to 22,739. IDPH said today there has been “no significant change” in the mortality rate in the last 28 days.
For the last seven days, the numbers of deaths in the State are 43, 24, 10, 17, 27, 42, and 21 today. The seven-day average is 26.
Variants in Illinois
IDPH is reporting a combined total of 7,898 confirmed cases of COVID-19 variants in the State. The combined total of variants is up 8% from one week ago.
Vaccinations in the State
A total of 11,175,656 doses of vaccine have been administered in Illinois. As of May 28, 82.74% of Illinois residents 65 and older have had at least one dose of a COVID-19 vaccine and 60.86% 16 and older have had at least one dose of a COVID-19 vaccine. These percentages continue to move up very slowly.
In the last seven-days, the average number of vaccinations given to Illinoisans is 58,378. On April 28, the seven-day average was 100,823; on April 21, it was 122,842. The pace of vaccinations has slowed down even though there is a larger supply and more places to get a vaccination.
1/ 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 of community burden 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 nucleic acid amplification tests (NAATs), including RT-PCR tests that are positive during the last 7 days. The two measures of community burden should be used to assess the incidence and spread of SARS-CoV-2 in the surrounding community (e.g., county) and not in the schools themselves.” The CDC provides a chart to assess whether the risk of transmission is low, moderate, substantial, or high. The CDC recommends different types of mitigations depending on the risk level. If the two indicators suggest different levels of risk, the mitigations recommended in the higher level of risk should be implemented, says CDC. The table below, reprinted from CDC’s report, provides CDC’s Indicators and Thresholds for Community Transmission of COVID-219.

2/ Number of Cases per 100,000 Population. On July 1, 2020, a network of research, policy and public health experts convened by Harvard’s Global Health Institute and Edmond J. Safra Center published a Key Metrics for COVID Suppression framework that provides guidance to policy makers and the public on how to target and suppress COVID-19 more effectively across the nation. The targets for new COVID-19 cases per 100,000 people are as follows (these are converted from cases per day to cases per week): a) less than 7 cases: “on track for containment;” b) 7 to 63 cases: “community spread,” rigorous test and trace program advised; c) 70 to 168 cases: “accelerated spread,” stay-at-home orders and/or rigorous test and trace programs advised; and d) 169+: ”tipping point,” stay-at-home orders necessary. The article is available here: https://globalepidemics.org/key-metrics-for-covid-suppression/
IDPH provides these categories and ratings: 1) “minimal” – fewer than 50 cases per 100,000 in a week; 2) “moderate” – between 50 and 100 cases per week; and 3) “substantial” more than 100 cases per 100,000 in a week. In its Metrics for School Determination of Community Spread, IDPH says the “target” is 50 cases per week per 100,000 people.
3/ The Test Positivity Rate. In addition, on May 26, 2020, Johns Hopkins University & Medicine Coronavirus Resource Center said on its website that “the World Health Organization (WHO) advised governments [on May 15, 2020] that before reopening, rates of positivity in testing (i.e., out of all tests conducted, how many came back positive for COVID-19) should remain at 5% or lower for at least 14 days.” Link: https://coronavirus.jhu.edu/testing/testing-positivity
The Harvard Global Health Institute (HGHI) says, “A network of research, policy, and public health organizations convened by Harvard and MIT called the TTSI Collaborative has agreed on a 3% test positive rate or below as a key indicator of progress towards suppression level testing.”
IDPH says the test positivity target is 5% or less. IDPH provides these categories and ratings: 1) “Minimal” – test positivity rate is equal to or less than 5%: 2) “Moderate” – test positivity rate is between 5% and 8%; and 3) “Substantial” – test positivity rate is over 8%. In its Metrics for School Determination of Community Spread, IDPH says the target is 5%.
4/ Calculations. The RoundTable calculates the number of cases per 100,000 using case data provided by IDPH and assuming that the population of Suburban Cook County is 2.469 million, that the population of Chicago is 2.710 million, and that the population of Illinois is 12.671 million.
5/ Northwestern University COVID-19 Cases. Ike C. Ogbo, Director of Evanston’s Health & Human Services Department, told the RoundTable that the COVID-19 cases reported by the City include cases of faculty, staff, and students attending Northwestern University who live in Evanston. The RoundTable asked the City in an FOIA Request to provide the number of NU students who tested positive for COVID-19 and who live in Evanston. The City refused to provide the data. On Oct. 26, the RoundTable appealed the City’s decision to the Public Access Counselor of the Attorney General’s Office. On Nov. 13, 2020, the City filed a response claiming it does not have any records showing the number of NU students who tested positive for COVID-19 and who live in Evanston.
The RoundTable has asked Northwestern University on several occasions to provide information breaking out the number of new COVID-19 cases of its faculty, staff and students by residency in Evanston. NU did not respond.
