If a ZIP was missing or was not valid, it is displayed as \"Unknown\". \n \nCases with a positive molecular (PCR) or antigen test are included in this dataset. Cases are counted based on the week the test specimen was collected. For privacy reasons, until a ZIP Code reaches five cumulative cases, both the weekly and cumulative case counts will be blank. Therefore, summing the \u201cCases - Weekly\u201d column is not a reliable way to determine case totals. Deaths are those that have occurred among cases based on the week of death.\n \nFor tests, each test is counted once, based on the week the test specimen was collected. Tests performed prior to 3/1/2020 are not included. Test counts include multiple tests for the same person (a change made on 10/29/2020). PCR and antigen tests reported to Chicago Department of Public Health (CDPH) through electronic lab reporting are included. Electronic lab reporting has taken time to onboard and testing availability has shifted over time, so these counts are likely an underestimate of community infection.\n\nThe \u201cPercent Tested Positive\u201d columns are calculated by dividing the number of positive tests by the number of total tests . Because of the data limitations for the Tests columns, such as persons being tested multiple times as a requirement for employment, these percentages may vary in either direction from the actual disease prevalence in the ZIP Code. \n \nAll data are provisional and subject to change. Information is updated as additional details are received. \n\nTo compare ZIP Codes to Chicago Community Areas, please see http://data.cmap.illinois.gov/opendata/uploads/CKAN/NONCENSUS/ADMINISTRATIVE_POLITICAL_BOUNDARIES/CCAzip.pdf. Both ZIP Codes and Community Areas are also geographic datasets on this data portal.\n \nData Source: Illinois National Electronic Disease Surveillance System, Cook County Medical Examiner\u2019s Office, Illinois Vital Records, American Community Survey (2018)", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://data.cityofchicago.org/api/views/yhhz-zm2v/rows.csv?accessType=DOWNLOAD", "mediaType": "text/csv"}, {"@type": "dcat:Distribution", "describedBy": "https://data.cityofchicago.org/api/views/yhhz-zm2v/columns.rdf", "describedByType": "application/rdf+xml", "downloadURL": "https://data.cityofchicago.org/api/views/yhhz-zm2v/rows.rdf?accessType=DOWNLOAD", "mediaType": "application/rdf+xml"}, {"@type": "dcat:Distribution", "describedBy": "https://data.cityofchicago.org/api/views/yhhz-zm2v/columns.json", "describedByType": "application/json", "downloadURL": "https://data.cityofchicago.org/api/views/yhhz-zm2v/rows.json?accessType=DOWNLOAD", "mediaType": "application/json"}, {"@type": "dcat:Distribution", "describedBy": "https://data.cityofchicago.org/api/views/yhhz-zm2v/columns.xml", "describedByType": "application/xml", "downloadURL": "https://data.cityofchicago.org/api/views/yhhz-zm2v/rows.xml?accessType=DOWNLOAD", "mediaType": "application/xml"}], "identifier": "https://data.cityofchicago.org/api/views/yhhz-zm2v", "issued": "2020-04-23", "keyword": ["link to article present", "historical", "covid-19", "zip code", "public health", "death", "health"], "landingPage": "https://data.cityofchicago.org/d/yhhz-zm2v", "modified": "2026-03-25", "publisher": {"@type": "org:Organization", "name": "data.cityofchicago.org"}, "theme": ["Health & Human Services"], "title": "COVID-19 Cases, Tests, and Deaths by ZIP Code - Historical"}
