Vaccination, weaning can contribute to IAV spread on swine farms
Hands of the farmworkers handling the infected 3-week-old piglets had a 91% contamination rate, while their clothes had a 97% contamination rate.

New research led by researchers at the University of Minnesota College of Veterinary Medicine reveals that farmworkers vaccinating and weaning 3-week-old piglets can indirectly and significantly contribute to the spread of the influenza A virus on swine farms. This information can help pig producers target biosecurity measures more strategically, curbing swine flu transmission and enhancing swine production outcomes.
Flu limits the growth rate of young pigs, causing great financial losses to farmers and food security issues worldwide. IAV can also infect humans, leading to serious illnesses that have the potential to cause a pandemic. This two-way transmission of IAV between pigs and humans helps the virus evolve and evade vaccines. So, research clarifying how IAV spreads can help protect the pig industry and avoid pandemics.
