Senecavirus A (SVA) remains an endemic concern in US swine herds, causing vesicular lesions and symptoms similar to foot-and-mouth disease (FMD). A recent study, led by Drs. Mariana Kikuti and Cesar Corzo, analyzed SVA outbreaks in breeding herds from 2015 to 2024, providing crucial data for the swine industry.
The study, utilizing data from the Morrison Swine Health Monitoring Project (MSHMP), found that SVA outbreaks were infrequent, affecting less than 2.5% of herds annually. The research covered more than 36,000 PCR tests from sites representing 60% of the US breeding herd, revealing that SVA’s incidence remains relatively low.
Temporal and regional trends were identified, with SVA more commonly reported during the latter half of the year, particularly from July to December. This seasonality calls for further research into the virus's transmission dynamics, especially in the Midwest, where outbreaks were more frequent due to high swine production density.
While SVA's overall impact is limited, it underscores the need for heightened vigilance, as outbreaks can mimic FMD. The study also highlights the importance of biosecurity protocols, such as monitoring animal movements and preventing cross-contamination, to manage the spread of SVA.
In summary, while the incidence of SVA is low, the study emphasizes continued surveillance and effective biosecurity measures. The findings will help swine producers and veterinarians improve disease prevention and management strategies, safeguarding the health of the US swine herd.
