HNL Lab Medicine to test for bird flu
Stacy Wescoe//February 21, 2025//
With bird flu cases on the rise, HNL Lab Medicine is responding.
Because of updated recommendations from the Centers for Disease Control and Prevention, HNL Lab Medicine will begin subtyping all positive influenza A samples from hospitalized patients to detect H5N1 Highly Pathogenic Avian Influenza.
HNL said the enhanced surveillance effort is part of a broader initiative to monitor potential bird flu cases and protect public health in the Lehigh Valley and surrounding areas.
H5N1 is a strain of avian influenza that primarily spreads among birds but has recently infected humans and other mammals. Outbreaks in poultry and dairy farms across the U.S. have raised concerns about possible transmission to humans. H5N1 is an influenza A virus, like many seasonal flu strains, and it requires subtyping to distinguish it from the common flu.
“While human cases remain rare, the presence of H5N1 in poultry and dairy farms across the country, as well as in geese in the Lehigh Valley, raises concerns for potential transmission,” said Dr. Caitlin Murphy, clinical lab director at HNL Lab Medicine. “With our region’s agricultural industry and wildlife interactions, enhanced monitoring is critical to public health. Subtyping influenza A samples from hospitalized patients will help quickly identify any potential human cases of H5N1 and enable a swift public health response.”
The Lehigh Valley is home to poultry farms, livestock operations, and migratory bird populations that HNL said could contribute to the spread of bird flu.
Recently, both geese and poultry in the area have tested positive, increasing concerns about local transmission.
However, Avian flu remains a low risk to the human population at this time.
