On May 13, the Center for Disease Control and Prevention updated its recommendations for people who are fully vaccinated against COVID-19. The two updates are:

  • “Fully vaccinated people no longer need to wear a mask or physically distance in any setting, except where required by federal, state, local, tribal, or territorial laws, rules, and regulations, including local business and workplace guidance
  • “Fully vaccinated people can refrain from testing following a known exposure unless they are residents or employees of a correctional or detention facility or a homeless shelter.”

The CDC issued the following recommendations that apply to non-healthcare settings. Fully vaccinated people can:

  • Resume activities without wearing masks or physically distancing, except where required by federal, state, local, tribal, or territorial laws, rules and regulations, including local business and workplace guidance
  • Resume domestic travel and refrain from testing before or after travel or self-quarantine after travel
  • Refrain from testing before leaving the United States for international travel (unless required by the destination) and refrain from self-quarantine after arriving back in the United States
  • Refrain from testing following a known exposure, if asymptomatic, with some exceptions for specific settings
  • Refrain from quarantine following a known exposure if asymptomatic
  • Refrain from routine screening testing if feasible.

For now, fully vaccinated people should continue to:

  • Get tested if experiencing COVID-19 symptoms
  • Follow CDC and health department travel requirements and recommendations

Gov. J.B. Pritzker said he will revise executive orders to align with new CDC guidelines on mask wearing by vaccinated individuals in indoor and outdoor spaces.

Risk of Community Spread

The seven-day average of new cases in Evanston, suburban Cook County, Chicago, and the State is trending downward.

For benchmarks used to assess the risk of spread, see footnotes 1–4.

Evanston – COVID

The City reported three new COVID-19 cases of Evanston residents today, compared to two yesterday.   

The average number of new cases per day in the last seven days is 4.6, down from the seven-day average of 6.9 on May 7.

In the last seven days, there was a total of 32 new COVID-19 cases of Evanstonians, which equates to about 43 new cases per 100,000 people in the seven-day period.

Evanston’s case positivity rate for the last seven days is 0.6%. 

There has been a total of 4,599 COVID-19 cases of Evanston residents during the pandemic, 148 of which are active. 

No Evanstonian has died due to 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 6 and May 12, there were eight 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. [5]

Illinois – COVID-19

In the State, there were 1,841 new COVID-19 cases reported today, down from 1,918 yesterday.     

Statewide, the average number of new cases per day in the last seven days is 1,715. The seven-day average one week ago on May 7 was 2,349, so today’s number is down by 27%. The downward trend continues.  

Today’s seven-day average is still higher than the low this year of 1,513 on March 15.

In the seven days ending May 14, the number of new cases per 100,000 people in the State was 95, down from 130 one week ago.

The seven-day case positivity rate for the State today is 2.7% and the test positivity rate is 3.1%.

On a Statewide basis, the number of hospitalizations due to COVID-19 was 1,708 as of midnight on May 14. The number is up from 1,112 on March 15.

The Illinois Department of Public Health 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 425, up from 227 on March 15. The number of patients on ventilators is 237, up from 95 on March 15.

On a Statewide basis, there were 49 deaths due to COVID-19 in the last 24 hours, which brings the total to 22,369. IDPH said today the trend in the mortality rate has been “increasing” in the last 28 days.  

For the last seven days, the numbers of deaths in the State are 22, 20, 12, 26, 26, 35, and 49 today. The seven-day average is about 27.

Variants in Illinois

IDPH is reporting a combined total of 6,312 confirmed cases of COVID-19 variants in the State.  Of those, 4,237 are the variant first discovered in the U.K.  

The combined total of variants is up 33% from one week ago.

Vaccinations in the State

A total of 10,229,330 doses of vaccine have been administered in Illinois. As of May 14, 81.06% of Illinois residents 65 and older have had at least one dose of a COVID-19 vaccine; and 57.59% of the residents 16 and older have had at least one dose of a COVID-19 vaccine. These percentages are moving up very slowly.

FOOTNOTES 

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.
