Influenza Statistics

Influenza (Flu)

About Influenza Statistics

Unlike other reportable diseases, MDH does not request that every case of influenza or every patient who goes to the doctor with influenza symptoms be reported to MDH. Tracking each case would overburden healthcare providers as well as MDH, without significant benefit. Instead, MDH uses several different surveillance systems to determine the burden of influenza disease in Minnesota each week (influenza-like illness [ILI] outbreaks at schools and long-term care facilities, outpatient/clinic visits for ILI, laboratory-confirmed influenza in hospitalized patients, influenza-related deaths, and MDH-PHL public health laboratory testing for influenza).

Updated weekly during the influenza season (October 2010-May 2011).
