McHenry County, IL School Metrics Dashboard

The McHenry County Department of Health (MCDH) is committed to reducing the risk of COVID-19 in schools and bringing children back to school as soon as it is safe to do so.

This dashboard is a resource to help McHenry County, Illinois school districts make data-informed decisions about their learning model during the COVID-19 pandemic.

Click the buttons below to view the Interim School Guidance (including the full decision matrix) and navigate to the McHenry County COVID-19 Dashboard and School and Student Guidelines web page.

Learning Models

The following graphic illustrates the movement (progression and regression) through the learning models (Virtual, Hybrid, and In-Person) used in the Decision Matrix. The term “Next Learning Model” is used when referencing the transition from virtual to hybrid and hybrid to in-person. The term “Previous Learning Model” is used when referencing the transition from in-person back to hybrid and from hybrid back to virtual.

Guidelines for Using Decision Matrix

• Schools are advised to consider first transitioning to hybrid learning from virtual learning before transitioning to full in-person learning.

• Schools are advised to consider being in the previous learning model for at least fourteen days before transitioning to the next.

• Schools are advised to consider meeting all four metrics before transitioning to the next learning model.

• Schools are advised to consider transitioning to the previous learning model if any two measures meet the threshold criteria for the previous learning model.

• MCDH will advise on potential mitigation strategies if any one measure meets the threshold criteria for the previous learning model.

• MCDH will work closely with schools to monitor compliance with contact tracing and monitoring, school absenteeism, disease activity, school capacity/infrastructure to implement guidelines, and other indicators to inform the transition between learning models.

Notice Regarding Outbreaks in Schools

An outbreak in a school is defined as two (2) confirmed cases of COVID-19 infections occurring within 14 calendar days of each other in individuals in the same classroom, team, or club. This is because the cases would be epidemiologically linked (known exposure to each other) with respect to place (same classroom, team, or club) and time (within 14 calendar days). This would prompt an investigation by the McHenry County Department of Health that may result in recommendations for testing and quarantining of all students/staff in the affected classroom, team, or club and/or other mitigation interventions to include but not limited to cancellation of activities or closure of school.

Metrics

All metrics are presented at the county level using a 3 day lag (unless otherwise specified). Incidence Rate, Positivity, and COVID-19-Like Illness (CLI) Hospital Admissions are updated daily, Monday-Friday between 4 pm and 6 pm. Weekly Count of New Cases Increase is updated weekly on Friday between 4 pm and 6 pm. All data is provisional and subject to change. The calculation and evaluation of all metrics can be found in the Interim School Guidance from MCDH [note: the exact methodology used for calculating metrics differs from that used by the Illinois Department of Public Health (IDPH) in some respects, leading to differences between these statistics and those presented by IDPH].

Incidence Rate

Incidence rate is displayed as a 7-day rolling average rounded to the nearest whole number. It is considered to have met the criteria for the next learning model when it is below the threshold (red and green lines) for at least 7 consecutive days. The metric is considered to have met the criteria for the previous learning model when it is above the threshold for at least 7 of the last 10 days. The data defaults to the last 10 days. Click "Filter by Date Range" to view historical data.

Positivity

Test positivity is displayed as a 7-day rolling average rounded to one decimal place. It is considered to have met the criteria for the next learning model when it is below the threshold (red and green lines) for at least 7 consecutive days. The metric is considered to have met the criteria for the previous learning model when it is above the threshold for at least 7 of the last 10 days. The data defaults to the last 10 days. Click "Filter by Date Range" to view historical data.

Last updated 10/23/2020. As of 10/21/2020, MCDH has decided to present the positivity statistics provided by IDPH. Although MCDH has complete confidence in the methodology it has been using, the health department has decided to utilize the same data as IDPH to stay consistent with how the State is interpreting and measuring positivity.

COVID-19-Like Illness (CLI) Hospital Admissions

CLI hospital admissions is displayed as a 7-day rolling average rounded the nearest whole number. It is considered to have met the criteria for next learning model when it is stable/decreasing. The metric is considered to have met the criteria for the previous learning model when it is increasing. Click "Filter by Date Range" to view historical data.

Weekly Count of New Cases Increase

Weekly count of new cases increase is considered to have met the criteria for next learning model when it is stable/decreasing. It is considered to have met the criteria for the previous learning model when it is increasing. The metric is not considered to have met the criteria for either the next learning model or previous learning model when it is fluctuating.
