In response to updated CDC recommendations, HNL Lab Medicine will begin subtyping all positive influenza A samples from hospitalized patients to detect H5N1 Highly Pathogenic Avian Influenza. This enhanced surveillance aims to monitor potential bird flu cases and safeguard public health in the Lehigh Valley and surrounding areas.

While human cases remain rare, the presence of H5N1 in local animals raises concerns for potential transmission.
H5N1 is an avian influenza strain 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 transmission to humans, particularly those in close contact with infected animals. While human cases remain rare, recent detections of H5N1 in geese and poultry in the Lehigh Valley highlight the need for increased monitoring.
“While human cases remain rare, the presence of H5N1 in local animals raises concerns for potential transmission,” said Dr. Caitlin Murphy, Clinical Lab Director. “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's agricultural presence-including poultry farms, livestock operations, and migratory bird populations-raises the risk of local transmission. Bird flu symptoms in humans can range from mild flu-like illness to severe respiratory distress and may also include conjunctivitis (eye irritation). Individuals should avoid contact with sick or dead birds, as well as their droppings, and follow proper hygiene practices.
While flu cases remain high, subtyping is recommended only for patients with known risk factors. Those with symptoms and recent exposure to animals should inform their provider, who will determine if subtyping is necessary. Avian flu remains a low risk to the general public at this time.
