04/10/2024: Lab Advisory: CDC Issues Health Alert for Highly Pathogenic Avian Influenza A(H5N1) Virus
Print
Audience: Clinical Laboratory Professionals
Level: Laboratory Advisory
On April 5, 2024, the U.S. Centers for Disease Control and Prevention (CDC) issued a Health Alert Network (HAN) message about a recently confirmed human infection with highly pathogenic avian influenza (HPAI) A(H5N1) virus in the United States following exposure to presumably infected dairy cattle. The U.S. Department of Agriculture (USDA) has recently reported detections of HPAI A(H5N1) in dairy cattle across multiple states.
The current risk posed by these viruses to the public remains low. CDC continues to work with USDA, FDA, and state health departments to monitor people exposed to animals infected with HPAI A(H5N1) viruses. Patients who meet epidemiologic criteria AND either clinical OR public health response criteria should be tested for influenza A(H5N1) virus infection by reverse-transcription polymerase chain reaction (RT-PCR) assay using H5-specific primers and probes at state or local public health departments.
For more information, including specific recommendations, please review the HAN in detail.
We encourage you to share this message widely with your network(s).
