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
Influenza meeting the following criteria should be reported to MDH within one working day:
- 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)
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.

How to report
- Yellow Disease Report Card
This disease may be reported using the MDH "Yellow Card."
- Minnesota Immunization Information Connection (MIIC)
You can report influenza by entering the information into the MIIC electronic system.
Any reportable infectious disease may be reported by phone to 651-201-5414 or 877-676-5414.
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).

Criteria for testing and specimen submission information.
Who is required to report
- Health care practitioners (health care facilities, medical laboratories, and in certain circumstances veterinarians and veterinary medical laboratories) are required to report disease to the Minnesota Department of Health (MDH) under Minnesota state law.
- Unless previously reported, every licensed health care provider who provides care to any patient who has, is suspected of having, or has died from a reportable disease is required to report.
- Any person in charge of any institution, school, child care facility, or camp is also required to report disease to MDH.
