    Influenza, COVID-19, RSV, and Other Respiratory Virus Laboratory Surveillance

    Metadata Updated: January 4, 2026

    This dataset includes aggregated weekly respiratory virus laboratory data that the Chicago Department of Public Health (CDPH) uses to monitor influenza, COVID-19, respiratory syncytial virus (RSV), and other respiratory virus activity in Chicago. The data represents respiratory viral PCR tests performed by several hospital laboratories in Chicago as well as two commercial laboratories serving Chicago facilities. Data are voluntarily reported on a weekly basis and do not contain patient demographic or geographic information. The data reported represent both Chicago and non-Chicago residents tested by the reporting facility.

    The respiratory viruses included are influenza, RSV, SARS-CoV-2, parainfluenza, rhinovirus/enterovirus, adenovirus, human metapneumovirus, and seasonal coronaviruses. Influenza laboratory data are available from 2010-2011 to present; for all other respiratory viruses data are available from 2019-2020 to present.

    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.
