TABLE 3-1 Timeline of 2002-2003 Exotic Newcastle Disease (END) Outbreak in Southern California



Two unrelated companion animal birds diagnosed with END. Federal efforts trace origin of birds to Southern California.


September 25

Index case END outbreak game fowl submitted to state diagnostic laboratory by private practitioner.


September 27

Second case in backyard chickens submitted to state laboratory.



Task force formed. Urban door-to-door disease eradication efforts begin.


October 1

National Veterinary Services Laboratories (NVSL) confirms END virus. U.S. Department of Agriculture (USDA) notifies state veterinarians and trade partners. EU bans import of U.S. poultry.



USDA transfers $7.4 million in funds from Virginia LPAI to END ($5 million for state, $2.4 million for USDA VS).



Initial development of rapid diagnostic assay begins.



Prototype Real-time Reverse Transcriptase (RRT) Polymerase Chain Reaction (PCR) used in conjunction with virus isolation by state laboratory to detect END.


December 23

First detection of END in a commercial flock, presumptive diagnosis by state laboratory using virus isolation and RRT PCR, officially confirmed December 21 by USDA testing.



Secretary of Agriculture approves $121.8M fund request for END control.



USDA declares extraordinary emergency.



Prototype RRT PCR used in federal laboratory.



END detected in Nevada game fowls (January 16, 2003). Nevada Task Force established. USDA declares extraordinary emergency for Nevada (January 17, 2003).
