In Minnesota, influenza is a reportable disease, although MDH typically only requests reports in certain circumstances. These reports help MDH document the first confirmed seasonal influenza case each year, monitor severity and strains circulating the state, and monitor for any unusual or new types.
These reporting guidelines do not apply to outpatient Influenza-like Illness Surveillance Network (ILINet) providers.
- Any Minnesota resident hospitalized with laboratory-positive influenza (via DFA, IFA, viral culture, EIA, rapid test, paired serological tests, or RT-PCR) IF the first positive influenza test specimen collection date is not more that 14 days before the patient’s admission date;
- Any influenza-related death (hospitalized or non-hospitalized) or critical illness (critical illness is defined as admission to the intensive care unit [ICU]);
- Unusual case incidence (clusters and suspect new novel strains). 2009 H1N1 is no longer considered a novel strain.
MDH is requesting that hospitals submit a respiratory specimen for all hospitalized patients with influenza-like illness (ILI) or clinical suspicion of influenza regardless of rapid influenza test status (positive, negative, not done) for testing by RT-PCR testing by the MDH-Public Health Laboratory (PHL).
