As Bird Flu Outbreak Expands in California, Dairy Farms Report It’s Worse Than They Expected

Oct 09, 2024

CNN A third farmworker has tested positive for bird flu in California, according to the state’s health department. If confirmed by the US Centers for Disease Control and Prevention, this would be the 17th human case of H5N1 flu in the US since March, when the virus was first detected in cows.

It comes as farmers and veterinarians in California are warning that the infection seems to be striking herds more severely than it has in other states, leading to higher percentages of sick and dead cows in affected herds.

There are no signs of more serious illness in people. Like the first two human cases in California, this third case involves a farmworker who was in contact with sick dairy cattle. Investigators don’t see any connections between the most recent case and either of the first two, suggesting that this is another instance of animal-to-human transmission, the California Department of Public Health said in a news release. In all three cases, symptoms were mild and involved red, bloodshot eyes, a sign of conjunctivitis.

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.
