U.S. CDC: Accelerated Subtyping of Influenza A in Hospitalized Patients

Please take a moment to review this information on accelerating subtyping of influenza A in hospitalized patients in the U.S.

To date, no human cases of H5N1 have been detected in Maine. Risk to the general public remains low. People with job- or recreation-related exposures to infected animals are at increased risk of H5N1 infection, especially when those exposures happen without use of appropriate personal protective equipment.

To monitor for possible H5N1 infection, the Maine CDC continues to request that all influenza-positive specimens come to Maine Health and Environmental Testing Laboratory (HETL) for subtyping.

Immediately notify Maine CDC at 1-800-821-5821 if H5N1 infection is suspected.
