• epiweek: Week of reporting (in epidemiological week calendar)

Details

The data retrieval from FluView and and RESP-NET pulls FluSurv-NET lab-confirmed hospitalization data as overall cumulative rates and weekly incident rates across reporting sites, age groups, sex, and race/ethnicity categories. Note that as of October 2024, the FluSurv-NET hospitalizations from RESP-NET begin in the 2018-19 season, while the FluView data goes back to 2009-10.
