The affected premises have been quarantined and the remaining birds were to be"depopulated" to prevent the spread of the disease.
The virus has been detected at two commercial turkey farms in southern Indiana, a flock of commercial broiler chickens in Kentucky and a backyard flock of mixed species birds in northern Virginia. The strain now circulating is H5N1 and is related to the 2015 virus. It has been circulating for months in Europe and Asia and was found in wild birds in Canada a few weeks ago and in a commercial flock in Canada a week before the first U.S. case was identified.
Anyone involved with poultry production should review their biosecurity activities to ensure the health of their birds, restrict human movement onto the farm and limit contact with poultry to only those who need to be there.
