Influenza A virus (IAV) is a common cause of respiratory disease in swine. IAV infects pig populations across the globe, but vary by geographic region. Transmission between different animal species, including pigs and people, plays a major role in the rise of new IAV strains. Control of IAV in humans and swine is mutually beneficial and vaccines play a role in effective control programs.
