Abstract:
Background Avian influenza viruses are still causing major concern not only to the poultry industry but also to human health across the globe. The live poultry markets and the small-scale local breeding of various species of birds in backyards are still playing important roles in the sustainability of most virulent influenza viruses, especially H5N8. Methods We investigated an outbreak of highly pathogenic avian influenza H5N8 in backyard flocks in Al Hasa, Eastern Saudi Arabia that occurred in 2017-18. Results A range of poultry including chickens, ostriches, ducks, pigeons and turkeys were clinically affected. Phylogenetic analysis suggested that this was a common source outbreak and caused by a virus closely related to H5N8 viruses causing outbreaks elsewhere in Saudi Arabia in early 2018. Conclusions Small backyard flocks are still contributing to the epidemiology and transmission of the H5N8.
