A newly published article in Frontiers of Veterinary Science offers a comprehensive look at two decades of data on Influenza A virus in swine, delivering key insights that can help producers and veterinarians better understand and manage respiratory disease in herds.
Authored by researchers from Iowa State University, the article analyzes 20 years of diagnostic data collected from six veterinary laboratories, compiled and tracked through the Swine Disease Reporting System (SDRS). The findings highlight the ongoing evolution of Influenza A virus in pigs, including the emergence of new strains and shifting disease patterns.
Dr. Lisa Becton, Associate Director at the Swine Health Information Center (SHIC), emphasized the value of this long-term surveillance.
“These reports help us identify changes in virus activity and trends over time, especially when pigs show signs of respiratory illness,” said Dr. Becton. “By examining multiple sample types and submissions across different age groups, we’re able to forecast virus patterns and explore intervention strategies.”
This data allows producers and veterinarians to monitor regional hot spots and disease outbreaks more effectively. It also supports decision-making around vaccination, biosecurity, and other control measures.
Dr. Becton noted that understanding when increases or decreases in virus submissions are expected can help model transmission patterns and assess herd-level interventions more accurately.
Access to the full article, as well as additional Influenza A resources, is available in SHIC’s June eNewsletter at swinehealth.org.
