Report date: 30 August 2006.
Reason for immediate notification: emerging disease or pathogenic agent with findings that are of epidemiological significance to other countries.
Precise identification of agent: koi herpesvirus (cyprinid herpesvirus 3).
Host species: Cyprinus carpio (common carp).
Date of first confirmation of the event: 16 June 2006.
Date of start of the event: 2 June 2006.
Clinical disease: yes.
Nature of diagnosis: clinical and laboratory.

Description of affected population: wild fish in fresh water.
Diagnosis:
Laboratory where diagnosis was made: Centre for Environment, Fisheries and Aquaculture Science (CEFAS), national reference laboratory, Weymouth; Species examined: pis; No. of animals examined: 15; Diagnostic tests used: - single round PCR(1)- gene sequencing; Date: 16 June 2006; Results: positive
Source of occurrences or origin of infection: unknown or inconclusive.
Control measures undertaken:
- tracing back;
- within-country movement controls.
Treatment of infected animals: no.
Other details/comments:
