Information For Health Professionals on
Novel Influenza A Virus (H7N9)

Ask patients with influenza-like illness (ILI) whether they have recent travel to China. Clinicians are reminded to consider influenza as a possible diagnosis when evaluating patients with acute respiratory illnesses, including pneumonia, even outside of the typical influenza season.

At this time, no cases of human infection with Novel Influenza A Virus (H7N9) have been identified in the United States.

Reporting, Specimen Collection, and Testing

  • MDH has recently instituted year round RT-PCR testing on hospitalized patients with ILI or clinical suspicion of influenza regardless of exposure history. Because of the concern of Novel Influenza A Virus (H7N9) we are also asking clinicians to inquire about recent (10 days or less) travel to China, and recent contact with a confirmed human case of infection with Novel Influenza A Virus (H7N9). Hospitalized patients meeting this clinical and exposure criteria will take priority for testing at MDH-PHL; however, we are still requesting that specimens be submitted to MDH-PHL regardless of exposure history.
