Influenza A Surveillance
On January 16, 2025, the CDC issued a Health Alert Network (HAN) Health Advisory to clinicians and laboratories due to sporadic human infections with avian influenza A (H5N1) viruses amid high levels of seasonal influenza activity. CDC is recommending a shortened timeline for subtyping all influenza A specimens among hospitalized patients and increasing efforts at clinical laboratories to identify non-seasonal influenza.
Clinicians and laboratorians are reminded to test for influenza in patients with suspected influenza and, going forward, to now expedite the subtyping of influenza A-positive specimens from hospitalized patients, particularly those in an intensive care unit (ICU). This approach can help prevent delays in identifying human infections with avian influenza A (H5N1) viruses, supporting optimal patient care and timely infection control and case investigation.
In response to CDC HAN00520, the Wisconsin Department of Health Services (DHS) issued an information update on January 23, 2025 with Wisconsin-specific guidance.
Subtyping can be performed either at your clinical laboratory, a commercial laboratory, or a public health laboratory. The current guidelines for enhanced and accelerated influenza A surveillance specimens being requested by WSLH are detailed below.
