The IDPH uses numerous indicators when determining if a county is stable in mitigating the spread of COVID-19. These indicators include:
- New cases per 100,000 people: If there are more than 50 new cases per 100,000 people in the county, this triggers a warning.
- Number of deaths: This indicates a warning when the weekly number of deaths increases more than 20 percent for two consecutive weeks
- ICU availability: If there are fewer than 20 percent of intensive care units available, this indicates a warning
- Weekly emergency room visits: A warning is indicated when the weekly percent of COVID-19-like illness increases by more than 20 percent for two consecutive weeks.
- Weekly hospital admissions: A warning is indicated when the weekly number of hospital admissions for COVID-19-like illness increases by more than 20 percent for two consecutive weeks.
- Tests performed: This metric is used to provide context and indicate if more testing is needed in the county.
- Clusters: This metric analyses the percent of COVID-19 cases associated with clusters or outbreaks and is used to understand large increases in cases.
