Influenza Reporting

Reporting the influenza-related complications below helps us understand risk factors for severe illness related to influenza and identify newly-emerging or resistant strains of influenza.

What to Report

  • Deaths in any Oregon resident less than 18 years of age with laboratory-confirmed influenza;
  • Any novel influenza virus (a human case of infection with an influenza A virus subtype that is different from currently circulating human influenza H1 and H3 viruses).
Portland Tri-County Area (Multnomah, Clackamas and Washington counties):
  • We request reports on all hospitalized patients of any age with laboratory-confirmed influenza. The Oregon State Public Health Laboratory will perform free typing and subtyping by PCR on specimens from any hospitalized patient with influenza-like illness, even if rapid tests have been negative. See influenza testing.
