Over the past month, virulent Newcastle disease cases have increased because people have violated the CDFA VND Regional Quarantine by moving infected birds or contaminated equipment and secondary spread to neighboring flocks.  Now there are 20 new cases under investigation, all linked to the recent Bloomington area outbreak.  Most of the cases are in San Bernardino County, with two in Riverside County and one in Los Angeles County. Backyard flocks as well as retail pet/feed stores are involved.
