In Minnesota, influenza is a reportable disease, although MDH typically only requests reports in certain circumstances. These reports help MDH monitor changes in disease activity, severity, and strains circulating the state, as well as for any new or novel strains.
These reporting guidelines do not apply to outpatient Influenza-like Illness Surveillance Network (ILINet) providers.
What to report
- 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 than 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 novel strains). 2009 H1N1 is no longer considered a novel strain.
- Please report within 1 business day.
How to report
- To report influenza disease that meets any of the above criteria, please:
Submitting clinical materials
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).
