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. 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 developed a plan for national END surveillance. This plan will enhance the already extensive surveillance underway.

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.

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 2,564 premises designated for depopulation, 95.9% 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.

* Caltrans is in the process of placing posters with information on END and related quarantine restrictions at approximately 100 highway rest areas throughout California.
