* Outpatients are not being routinely tested for influenza; therefore reports of confirmed cases cannot be relied upon to provide an accurate picture of novel H1N1 cases that do not require hospitalization. In order to assess influenza activity among outpatients, IDPH continues to obtain information from sentinel providers across the state, and will post surveillance reports on a weekly basis at www.idph.state.il.us/flu/fluupdate08-09.htm.
