Paul F Horwood et al. Emerg Infect Dis. 2018 Feb.

Abstract

Longitudinal surveillance of 2 live bird markets in Cambodia revealed year-round, high co-circulation of H5, H7, and H9 influenza viruses. We detected influenza A viruses in 51.3% of ducks and 39.6% of chickens, and co-infections, mainly by H5 and H9 viruses, in 0.8% of ducks and 4.5% of chickens.

Keywords: Cambodia; H5N1; H7N9; H9N2; Influenza; Phnom Penh; Takeo; avian; avian influenza virus; carcass wash water; chicken; cloacal; co-circulation; co-infection; duck; live bird markets; oropharyngeal; poultry; southeast Asia; swab; viruses.
