Chart of COVID-19 test results by day.

Daily case counts and percentage of all ED visits for COVID-Like Illness. See the underlying dataset for definitions.

A trailing 60 days is shown by default for ease of reading but this period can be adjusted with the filter to the right.

Date is the end date of a seven-day window over which the number of daily deaths is averaged before using population to calculate the rates.

Note that because of delayed reporting, counts from recent dates are likely to be preliminary and to increase as the Department of Public Health gets additional reports.

This dataset includes aggregated weekly metrics of the surveillance indicators that the Department of Public Health uses to monitor influenza activity in Chicago. These indicators include:

- Influenza-associated ICU hospitalizations for Chicago residents, which is a reportable condition in Illinois (HOSP_ columns)

- Influenza laboratory data provided by participating sentinel laboratories in Chicago (LAB_ columns)

- Influenza-like illness data for outpatient clinic visits and emergency department visits. (ILI_ columns)

For more information on ESSENCE, see https://www.dph.illinois.gov/data-statistics/syndromic-surveillance

All data are provisional and subject to change. Information is updated as additional details are received. At any given time, this dataset reflects data currently known to CDPH. Numbers in this dataset may differ from other public sources.

Department of Public Health app based on this list: https://measlesvax.chicago.gov/ -- List of sites that guarantee specific, non-flu vaccines will be in-stock and available for the time period indicated in each record -- filtered to MMR for this view. For flu shot locations, go to https://data.cityofchicago.org/Health-Human-Services/Flu-Shot-Locations-2014-Present/w3hg-pyhz.

Note for using this dataset that it is always recommended that individuals contact their healthcare provider or closest pharmacy to check on vaccine availability prior to walking in for vaccination. Each vaccine has a filtered view showing only records from that vaccine and blank filter conditions that can be used to filter further by time. These filtered views can be used for almost all purposes as if they were datasets, although any additional criteria added by a user would need to be saved to a new filtered view in order to use it in this manner. This dataset approximately follows https://github.com/codeforamerica/flu-shot-spec/blob/master/data-format.csv and is designed for use by https://github.com/tkompare.

Comprehensive information about the Chicago Department of Public Health (CDPH)'s mental health clinics and community partners.

Information includes location of site(s), hours of operation, populations served, specific service types, and contact information.

List of Chicago Department of Public Health free flu clinics offered throughout the city in fall 2013. The names in this view comply with the emerging national standard for flu clinic data. For more information on this standard, please see https://github.com/CityOfPhiladelphia/flu-shot-spec.

Please see the parent "Based on" dataset for a description of these data. As noted there, the full dataset includes an "All" age group, which can result in some double-counting when summing totals. This filtered view excludes the "All" records, which may make it easier to use for some purposes.

This dataset contains the weekly estimated influenza risk level for each ZIP Code in Chicago. Estimates are made during flu season, which goes from MMWR week 40 to week 20 of the following year.

The risk level is based on observed level of Influenza-Like Illness (ILI). ILI Activity Level is determined as follows: ILI percentage for each ZIP Code for the week is compared to the mean ILI percentage during the non-influenza months (summer months). Level 1 corresponds to an ILI percentage below the mean, level 2 to an ILI percentage less than one standard deviation (SD) above the mean, level 3 to an ILI percentage more than one, but less than two SDs above mean, and so on, with level 10 corresponding to an ILI percentage more than eight SDs above the mean.

For more information on ESSENCE, which compiles the estimates, see https://www.dph.illinois.gov/data-statistics/syndromic-surveillance

Public alerts for the Chicago Department of Public Health's (CDPH) Health Alert Network (HAN).

The HAN provides CDPH with the capacity for quick, efficient, reliable, and secure web-based communication with CDPH staff, providers of medical care, laboratories, first responders and other local public health agencies and partners. The HAN facilitates CDPH’s day-to-day activities, including outbreak detection, investigation, and emergency response.

This dataset is published as a convenience to complement the HAN site, itself. While alerts generally are published promptly, for uses involving risk to health and/or life, please contact the HAN team directly to discuss other methods of receiving alerts.

The contents of this dataset, the HAN site, and CDPH's Web site are not intended to be substitutes for professional medical advice, diagnosis, or treatment. Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition. Professional medical advice should not be ignored because of something you have read on this data portal or any CDPH site.

Concentrations of the SARS-CoV-2 virus (the COVID-19 virus) gene in the Chicago sewer system, as measured at eight sewershed sites. These sites represent catchment areas that describe wastewater from 319,700 Chicagoans as of January 2023.

Because SARS-CoV-2 is shed in human feces, this method can be used to estimate changes in COVID-19 at different times and locations across Chicago. While the data in this dataset do not indicate how many people were infected with SARS-CoV-2, differences in the the normalized_n1 indicate whether the proportion of individuals at the site who are shedding that virus has changed.
