Small Pests, Bigger Threats: Flies and Gnats Spread Swine Rotaviruses and Sapovirus

Aug 02, 2023

Annoying. Bothersome. Irritating. Inconvenience. Pest. No matter how you describe Musca domestica, aka the house fly, and its friend the gnat, one thing's for sure - they are a nuisance and pose a threat to your swine herd.

Everyone knows the small stature of flies and gnats and their ability to fly allows them to easily enter and exit barns and vehicles while bringing with them viral, bacterial and parasitic pathogens. For the first time ever, a study led by Allison Knox of the Walcott Veterinary Clinic in Walcott, Iowa, shows the ability of house flies and gnats to transmit rotavirus and sapovirus in swine nurseries.

Video: How Data Predicts Swine Outbreaks - Swaminathan Jayaraman

In this episode of The Swine it Podcast Show Canada, Swaminathan Jayaraman, Research Assistant and PhD Candidate at Iowa State University College of Veterinary Medicine, explains how integrated data systems can improve disease surveillance in swine production. He discusses combining diagnostics, animal movement data, production records, and spatial analytics to identify risks earlier and support proactive decision-making for PRRS, PED, and swine influenza. Listen now on all major platforms!

"Disease surveillance remains largely reactive because outbreaks are often confirmed only after transmission has already occurred across multiple connected production sites."

Meet the guest: Swaminathan Jayaraman / swamjay is a Graduate Research Assistant at Iowa State University College of Veterinary Medicine. With academic training in management information systems and engineering, he focuses on integrating diagnostic, production, and movement data to improve disease surveillance and decision support in swine production systems.
