All flocks within a 1-km radius of the positive flock have been depopulated. A total of 40 backyard flocks have been quarantined.

DNA sequencing analysis confirms that the Texas outbreak was caused by a separate introduction of virus and not by the movement of virus from the affected areas in California, Nevada, or Arizona (see follow-up report No. 1).

Early detection and rapid response have worked well to contain and eliminate this outbreak.
