Highly pathogenic avian influenza in the Republic of Korea (diagnosis
confirmation): (Date of previous outbreak of highly pathogenic avian
influenza in the Republic of Korea reported to the OIE: 2004).
Information received on 26 Nov 2006 from Dr Chang-Seob Kim, Chief
Veterinary Officer, Animal Health Division, Ministry of Agriculture
and Forestry (MAF), Gwacheon:
Report date: 26 Nov 2006.
Identification of agent: highly pathogenic avian influenza virus subtype H5N1.
Date of 1st confirmation of the event: 22 Nov 2006.
Nature of diagnosis: clinical, post-mortem and laboratory.
Location of the outbreak: Iksan city (Jeollabuk-do province).
Number of animals in the outbreak: 6500 cases, 13 300 susceptible
animals, 6500 deaths and 6800 animals destroyed.
Description of affected population: a parent stock farm for broiler
chickens (45 weeks old).
Laboratory where diagnostic tests were performed: National Veterinary
Research and Quarantine Service, Anyang, Kyonggi.
Diagnostic tests used: PCR, haemagglutination inhibition test,
sequence analysis: amino acid sequence at cleavage site reveals a
HPAI profile, cytopathic effect on cell culture, neutralisation.
Source of outbreak or origin of infection: unknown or inconclusive.
Control measures undertaken: control of wildlife reservoirs;
stamping out (all poultry in the affected farm); quarantine (removal
of feed, manure and egg plates out of the farms within a 3-km radius
zone around the outbreak is prohibited); movement control inside the
country (a 10-km radius zone around the infected holding); screening;
zoning; burial of dead and destroyed poultry as well as of feed,
manure and egg plates in the affected farm; disinfection and
surveillance intensified in the poultry holdings.
Control measure to be undertaken: stamping out (all poultry within a
0.5-km radius zone around the outbreak).
[As expected and as reported previously, this outbreak is an H5N1.
This report indicates that multiple tests have been completed. Of
course, it is also important to know at the molecular level, which
previous strain, if any, is most closely related to this new outbreak
of the virus.
