Afonso Virulent viruses of the panzootic Newcastle disease virus of sub-genotype VIIi were repeatedly isolated (2011-2016) from commercial chickens and from multiple non-poultry avian species in Pakistan. These findings provide evidence for the existence of epidemiological links between Newcastle disease outbreaks in commercial poultry and infections with virulent NDV strains in other avian species kept in proximity to poultry. Our results suggest that the endemicity of Newcastle disease in Pakistan involves multiple hosts and environments.
