“Piglets as well as sows play a key role in transmitting the virus” Veterinary virologist Dr. Pia Ryt-Hansen from the University of Copenhagen suggests practical lessons for controlling Porcine Respiratory Disease Complex viruses, based on her research into swine Influenza A virus or IAV-S in a sow herd in Denmark. Hear how production strategies and even maternally derived antibodies can actually contribute to viral persistence in the herd, plus potential benefits from the application of diagnostic tools such as genomic sequencing of virus identity and monitoring of coughing by pigs in the barn.
