Eligibility Opens for Vaccinations
On April 12, everyone 16 and over will be eligible to receive a vaccine to protect against COVID-19. Appointments are still necessary to receive a vaccine. The Governor’s office said yesterday that that more than 1,000 vaccination locations were operating across the State.
“The State of Illinois alone has administered over 6.7 million doses of vaccine,” said Governor JB Pritzker. “Seventy-three percent of our seniors, and 42% of our 16 and over population, has had at least one dose. Nearly one quarter of our adult population has been fully vaccinated. Our fight to stay safe and protect ourselves isn’t over, but with each day and each dose, we move closer and closer to putting this pandemic to an end.”
“COVID-19 vaccination is one of the most powerful and effective tools we can use to fight this pandemic together,” said Dr. Ngozi Ezike, Director of the Illinois Department of Public Health. “We now have more providers than ever before, and we are working diligently to make sure underserved communities and those disproportionately affected by COVID-19 have access to the vaccine.”
The State has established 20 State-supported mass vaccination locations across Illinois where residents from anywhere in Illinois can be vaccinated. All State-supported vaccination sites require appointments. Information about the location of mass vaccination sites as well as other sites and information about appointments can be found on the coronavirus.illinois.gov website.
Risk of Community Spread
The charts in the above box show that new cases are continuing to rise in Suburban Cook County, Chicago, and Illinois.
For total cases in the last seven days per 100,000 people, IDPH says that more than 100 cases indicates a risk of “substantial spread.” The Centers for Disease Control and Prevention says that more than 100 cases indicates a risk of “high transmission.” [1, 2 and 3]
For test positivity in the last seven days, IDPH uses a target of 5%. The CDC says between 5% and 7.9% represents a “moderate” risk of transmission. [1, 2 and 3]
Evanston – COVID
The City reported nine new COVID-19 cases of Evanston residents today, down from 18 yesterday.
The average number of new cases per day in the last seven days is 12.1, down from the seven-day average of 16.7 on April 2.
In the last seven days, there was a total of 85 new COVID-19 cases of Evanstonians. The 85 new cases equate to about 115 new cases per 100,000 people in the seven-day period.
Evanston’s case positivity rate for the last seven days is 1.1%.
There has been a total of 4,311 COVID-19 cases of Evanston residents during the pandemic, 205 of which are active.
No Evanstonian died due to COVID-19 in the last 24 hours. The number of deaths due to COVID-19 remains at 115.
Impact of Northwestern University. Northwestern University has posted data on its website reporting that between April 1 and April 7, there were 45 new confirmed COVID-19 cases of NU faculty, staff, and students. If the faculty, staff or students reside in Evanston, they are included in the City’s numbers. The number reported by NU, though, includes people who live outside of Evanston. 
Illinois – COVID
In the State, there were 4,004 new COVID-19 cases reported today, up from 3,739 yesterday. The last time new cases exceeded 4,000 in a single day was Jan. 29.
Statewide, the average number of new cases per day in the last seven days is 3,122. The seven-day average one week ago on April 2 was 2,628, so today’s number is up by 19%. The average number is up 51% in the last two weeks.
Today’s seven-day average is up from a low this year of 1,513 on March 15. Cases have almost doubled since then. An accompanying chart shows the trend.
In the seven days ending April 8, the number of new cases per 100,000 people in the State was 172, up from 145 one week ago.
The seven-day case positivity rate for the State today is 4.2% and the test positivity rate is 4.8%.
On a Statewide basis, the number of hospitalizations due to COVID-19 was 1,808 as of midnight on April 8. This is up from 1,112 on March 15.
The number of patients using ICU beds is 369, up from 227 on March 15. The number of patients on ventilators is 163 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 21,476.
For the last seven days, the numbers of deaths in the State are 11, 14, 11, 13, 28, 34, and 21 today. The seven-day average is 19.
Variants in Illinois
IDPH is reporting a total of 704 confirmed cases of COVID-19 variants in the State. Of those, 552 are the variant first discovered in the U.K.
Vaccinations in the State
A total of 8,841,285 doses of vaccine have been delivered to providers in Illinois, including Chicago and long-term care facilities. IDPH is currently reporting that a total of 6,871,645 doses of vaccines have been administered.
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, 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, Johns Hopkins University & Medicine Coronavirus Resource Center said on its website that “the World Health Organization (WHO) advised governments [on May 15] 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, 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.
