Emergency Management Warning 79:
Exotic Newcastle Disease Confirmed in the United States
All information in the following Notice marked with an asterisk (*)
identifies changes since the last Notice was sent out.
Exotic
Newcastle disease (END) was confirmed on October 1, 2002, in the State of
California, and has now spread beyond backyard flocks to affect 22
commercial operations in California. On January 16, 2003, END was also
confirmed in a backyard flock in the State of Nevada. A backyard flock was
confirmed with END on February 4, 2003, in the State of Arizona. * On
April 9, 2003, END was confirmed in backyard fowl in Texas. Clinical signs
in infected birds include respiratory, nervous, and gastrointestinal
signs. Mortality is up to 90% of exposed birds. Investigations are
on-going and all figures are pending final validation. Animal and Plant
Health Inspection Service (APHIS) personnel and other federal government
personnel are working with the States to consider additional resources to
meet the labor demands at the Task Forces. APHIS has implemented a plan
for enhanced national END surveillance.

Operational Update
Effective January 7, 2003, APHIS imposed a federal quarantine that
regulates the interstate movement of all species of birds and poultry
products from Imperial, Los Angeles, Orange, Riverside, San Bernardino,
San Diego, Santa Barbara, and Ventura Counties, CA.
Effective January 17, 2003, APHIS imposed a federal quarantine that
regulates the interstate movement of all species of birds and poultry
products from Clark and a portion of Nye County, NV.
Effective February 10, 2003, APHIS imposed a federal quarantine that
regulates the interstate movement of all species of birds and poultry
products from all of La Paz and Yuma Counties and a portion of Mohave
County, AZ.
The U.S. Department of Agriculture (USDA) has declared an
extraordinary emergency for the States of Arizona, California, and Nevada.
These declarations allow USDA to apply federal authority within Arizona,
California and Nevada.
* END has been confirmed in backyard fowl near El Paso, TX. The
sequencing at the cleavage site of the fusion protein gene is RRQKR/F,
which is identical with that found in the Arizona, California, and Nevada
isolates of ENDV. The nucleotide sequence of the 180 bp segment flanking
the cleavage site is 100% identical with the Arizona, California, and
Nevada isolates of ENDV. Additional sequencing and phylogenetic analysis
of a larger segment of the matrix and fusion genes is in progress and
should be available sometime next week. The infected flock contained 164
backyard fowl. The premises has been depopulated and depopulation of
adjacent and dangerous contact sites has begun.
* APHIS is
proceeding with a declaration of extraordinary emergency and the
establishment of a federal quarantine for the Texas counties of El Paso
and Hudspeth, and the New Mexico counties of Luna, Dona Ana and Otero. An
Incident Command Post is being established in El Paso, Texas, for task
force activities in TX and NM.
Currently there are 22 commercial flocks in the State of California
affected by END. The breakdown of the commercial premises involved is as
follows: 4 premises in Riverside County (3 infected and 1 contact), 7
premises in San Diego County (7 infected), and 11 premises in San
Bernardino County (11 infected). * Of the 2,556 premises designated
for depopulation, 98.1% have been completed.
* The Inland Desert
and South Coast ICP's have realigned their service territories so that all
of Los Angeles County will now be handled by the South Coast ICP. The
South Coast ICP also will be responsible for all of San Diego County,
except in cases involving commercial premises. Previously, the Inland
Desert ICP handled portion of Los Angeles County, as well as certain areas
of San Diego County (both backyard and commercial premises).
* The
Central Valley Incident Command Post in Modesto, CA, is staffed and
working cooperatively with approximately 15 20 county officials to
implement efficient surveillance measures throughout the Central
Valley.
Outreach Activities
On a daily basis, Task Force personnel are communicating information
concerning surveillance, depopulation, and cleaning and disinfection
operations to all affected city managers in Southern California.
*
Currently, Task Force information personnel field approximately 450 calls
per week from the public through the Joint Information Center phone bank.
This is a twenty-fold increase from the number of calls in October 2002.
On average, approximately 300 of these calls require follow-up action by
the Inland Desert or South Coast Incident Command Posts.
* The Task
Force information staff provides daily updates to approximately 50 media
outlets in California. In addition, in Area Command alone, the information
staff field approximately 70 media calls per
week.
