The Swine Health Information Center (SHIC), in collaboration with the American Association of Swine Veterinarians (AASV), hosted a webinar on influenza A viruses on Friday, April 19, 2024. The goal of the webinar was to understand the threat HPAI H5N1 poses to domestic livestock species and to inform producers of actions that can be taken to prevent infection on-farm. This article includes an overview of influenza A viruses, global and domestic distribution of the virus, IAV swine surveillance programs, and research outcomes for HPAI H5N1 experimental infection in swine. A second article includes information regarding the clinical presentation and epidemiology of the multi-state dairy herd outbreak and a review of biosecurity considerations for swine farms to mitigate risks of HPAI H5N1. The webinar garnered high interest with 1341 registrants and 921 joining the webinar live from 30 countries.
The webinar recording is available here.
Influenza A viruses are constantly evolving and pose a risk to domestic livestock species. To address and mitigate the impact of emerging influenza strains for producers, SHIC and AASV collaborated to provide this influenza A virus webinar with the latest information on influenza in domestic livestock species. Prevention efforts should focus on actions to reduce biosecurity risks including the use of outbreak investigation tools to identify biosecurity hazards at the farm. Understanding the status of influenza in US pig populations through targeted surveillance provides information on virus evolution, distribution and support of diagnostic tests and vaccines. Influenza viruses present a challenge for swine health and production and tools exist to reduce the impact this disease can have on pork producers.
