Note: This dataset will be decommissioned and replaced by another in December 2018. A link to the new dataset will be provided once available.This dataset includes clinical laboratory confirmed cases of influenza that meet the New York State Department of Health’s (NYS DOH) case definition of a positive result on any of the following influenza laboratory tests: rapid antigen detection test (RAT), viral culture, reverse transcriptase polymerase chain reaction (RT-PCR) test, direct immunofluorescence antibody staining (DFA) test, and indirect immunofluorescence antibody staining (IFA) test.

This dataset includes weekly counts of laboratory-confirmed influenza (flu) cases, by county and influenza type, going back to the 2009-10 season. The primary goal of this dataset is to provide users timely information about local influenza activity throughout the current influenza season. Although each influenza season is unique, historical data is also provided for trend comparison. In view of persisting elevated influenza activity throughout NYS, NYSDOH is extending the surveillance 2021-2022 season beyond May until influenza activity has decreased. In view of persisting elevated influenza activity throughout NYS, NYSDOH is extending the surveillance season beyond May until influenza activity has decreased.

Cases are included that meet the New York State Department of Health’s (NYSDOH) standardized case definition, i.e., a positive result on any of the following influenza laboratory tests:
• Rapid Influenza Diagnostic Tests (RIDT)
• Immunofluorescence assays (DFA and IFA)
• Rapid Molecular Assays
• Reverse Transcriptase Polymerase Chain Reaction (RT-PCR)
• Other Nucleic Acid Amplification tests
• Viral Culture
Please see the overview document for more details about NYSDOH’s influenza case definition. Cases reported during the CDC-defined influenza surveillance season (week 40-week 20 of the next calendar year; October through mid-May) are included.

This dataset includes weekly counts of laboratory-confirmed influenza (flu) cases by age group.

This dataset includes weekly aggregate counts of persons hospitalized with laboratory-confirmed influenza (flu), by county beginning with the 2020-21 season. The primary goal of this dataset is to provide users timely information about influenza-associated hospitalizations throughout the current influenza season. Although each influenza season is unique, historical data is provided for trend comparison.

This dataset reports the number of people vaccinated by New York providers who have received a dose of the annual COVID-19 vaccine and the number who have received the annual Influenza vaccine, beginning with the 2024-2025 season.

Note: This dataset replaces two prior COVID-19 vaccination datasets. Please refer to the notes section below for links to the archived data.
