Emergency Management Warning 92:
Exotic Newcastle Disease Confirmed in the United
States
Exotic Newcastle disease (END) was confirmed on October 1, 2002, in the
State of California, and has 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 also 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.
• Effective
April 10, 2003, APHIS imposed a federal quarantine that regulates the
interstate movement of all species of birds and poultry products from all
of El Paso and Hudspeth Counties, TX, and Dona Ana, Luna, and Otero
Counties, NM. The federal quarantine was placed on counties beyond the
infected county due to their proximity to the infected county.
• A
quarantine was placed on a portion of New Mexico because of its proximity
to the infected area in the State of Texas
• The U.S. Department of
Agriculture (USDA) has declared an extraordinary emergency for the States
of Arizona, California, Nevada, Texas, and New Mexico. These declarations
allow USDA to apply federal authority within Arizona, California, Nevada,
New Mexico, and Texas.
• Currently there are still 19 commercial
premises 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), 6 premises in San Diego County (6 infected),
and 9 premises in San Bernardino County (9 infected).
• A backyard
premises near the town of Mojave in eastern Kern County, CA, has tested
positive for END. The premises has epidemiological links to Los Angeles
County, CA, which is currently in the quarantine zone. The virus had at
the fusion protein cleavage site a multiple basic amino acid sequence
(SGGRRQKR/FVGAI) compatible with and similar to that of previously
isolated END viruses in Southern California. The positive premises and
contact premises have been depopulated. APHIS is developing an expansion
of the federal quarantine zone to encompass the southeast corner of Kern
County.
• DNA sequencing analysis confirms that the Texas END
outbreak was caused by a separate introduction of virus and not by
movement of virus from the affected areas in California, Nevada, or
Arizona. Intensified surveillance in El Paso County, TX, and the
surrounding areas has yielded no further positive cases, suggesting that
our early detection and swift response has worked well to contain and
eliminate this outbreak.
Outreach Activities
• The Task Force recently participated in celebrations in California'
Hispanic and Latino communities to help educate citizens about END.
Approximately 500,000 people received Spanish-language educational
materials at the Fiesta Broadway event. The Task Force also participated
in the Cinco de Mayo celebration in Lincoln Park.
• END Task Force
personnel will pass out educational materials at their booth during a
Mother's Day celebration in Bakersfield, CA. The sponsor of the
celebration is a local Spanish-language radio station.
• In
conjunction with the Task Force, the Texas Animal Health Commission in
Austin continues to send out information packets to stakeholder
organizations; most recently, the commission has mailed materials to feed
stores, veterinary clinics and pet stores.
