Meeting • July 16, 2024 CDC COCA Call – Update on Highly Pathogenic Avian Influenza A(H5N1) Virus for Clinicians and Healthcare Centers

Highly Pathogenic Avian Influenza (HPAI) (H5N1) virus is widespread among wild birds and continues to cause outbreaks in poultry and spillover to mammals. In March 2024, HPAI A(H5N1) virus was detected in dairy cattle. To date, there have been three human cases of HPAI A(H5N1) virus infection identified in dairy farm workers in the United States. The risk to the public from HPAI A(H5N1) viruses is low; however, people who have job-related or recreational exposure to infected birds or animals, including dairy cattle, are at greater risk of HPAI A(H5N1) virus infection. During this Centers for Disease Control and Prevention (CDC) Clinician Outreach and Communication Activity (COCA) Call, presenters will give an update on the current outbreak in the United States and current CDC surveillance and monitoring efforts. They will also provide information for clinicians on testing, using antivirals, and infection prevention and control recommendations.

At the conclusion of the session, the participant will be able to accomplish the following:

1. Discuss the epidemiology and clinical features of human cases of HPAI A(H5N1) virus infection.
2. Describe risk of human infection with HPAI A(H5N1) viruses, identify higher risk populations, and what to assess in clinical settings.
3. Describe testing, using antivirals, and infection prevention and control recommendations for patients with HPAI A(H5N1) virus infection.
