Swine Influenza: Management and Challenges

Management and challenges of dealing with swine influenzaChallenges of Swine Influenza Dr. Dyneah Classen presents on the challenges of surveillance and management of swine influenza. Dr. Classen details several of the protocols that should be done for surveillance. Surveillance data is needed to help determine farm vaccination strategies. Dr. Classen concludes with observations that vaccination of the entire breeding herd can reduce viral shedding in both sows and suckling piglets plus suckling piglets may be a source of virus to other pigs.

Fairs plus Influenza 2012 and 2013 follow-up

Swine Influenza and FairsSwine Influenza and Fairs Dr. Jennifer Koeman updates with how the National Pork Board is supporting the surveillance, education, and awareness campaigns around swine influenza. Dr. Koeman presents a historical perspective on swine influenza and pork economics plus how past experiences are being integrated into response plans. She concludes with observations that there is continued focus on improving swine health and monitoring for influenza and that biosecurity is important to minimize influenza transmission.

Humans and Animals at State Fairs

Do not Lick The AnimalsDon't Lick The Animals Dr. Joni Scheftel provides a public health perspective on the influenza A virus and the human-interface. Dr. Scheftel notes that up until 2012, the occurrence of influenza A virus (swine influenza) in humans was quite rare. But in 2012 the U.S. cases of variant influenza A jumped to 306 from 14 in 2011. Dr. Scheftel concludes with information on action steps taken in 2013 to educate people in Minnesota about exposure to pigs through out the year, like at fairs and live markets.

Wean-Finish Populations With Swine Influenza

Dynamics of swine influenza in a wean-finish populationSwine Influenza and Wean-Finish Populations Andres Diaz, Ph.D. student, University of Minnesota, College of Veterinary Medicine, presents information the dynamics of influenza infections in a wean to finish population. Mr. Diaz suggested that wean pigs can be a source of influenza A virus to other swine populations and that the maternal immunity does not protect weaned pigs from influenza A virus infection but it did reduce transmission.

Human-Animal Interface and H3N2 in Swine

H3N2 influenza A virus in swine and the human-animal interfaceLooking at H3N2 Influenza A Virus in Swine Dr. Amy Vincent details USDA's influenza A virus (H3N2) surveillance program. Dr. Vincent highlights the infrastructure details that provide support plus outlines the sciences and protocols used in the surveillance. Dr. Vincent points out the challenges some of the vaccines have and what should be done at the human-animal interface.

What is the Prevalence of Swine Influenza Virus in Weaning Pigs?

Swine influenza virus prevalence and risk factors in weaning-age pigsSwine Influenza Virus Prevalence Matt Allerson, Ph.D. student, University of Minnesota, College of Veterinary Medicine, introduces what influenza A virus is and how it is classified. He shares information on the economic impact of influenza A virus to farms and offers some research on how to approach handling sick pigs to reduce the spread of influenza A virus.

Swine Influenza, Human-Animal Interface, and Being Prepared

Influenza & the Human-Animal InterfaceInfluenza & the Human-Animal Interface The flu season for pigs is starting up and there are actions barn staff can take to help limit exposure and improve surveillance. Several presentation to help with training and awareness on influenza A, surveillance, and human-animal interactions were shared at the 2103 Allen D. Leman Swine Conference.
