    Swine influenza in Sri Lanka.
    (Centers for Disease Control and Prevention (CDC), 2013) Perera, H.K.K.; Wickramasinghe, G.; Cheung, C.L.; Nishiura, H.; Smith, D.K.; Poon, L.L.; Perera, A.K.; Ma, S.K.; Sunil-Chandra, N.P.; Guan, Y.; Peiris, J.S.
    To study influenza viruses in pigs in Sri Lanka, we examined samples from pigs at slaughterhouses. Influenza (H3N2) and A(H1N1)pdm09 viruses were prevalent during 2004-2005 and 2009-2012, respectively. Genetic and epidemiologic analyses of human and swine influenza viruses indicated 2 events of A(H1N1)pdm09 virus spillover from humans to pigs
