Source of the outbreak(s) or origin of infection Unknown or inconclusive
? Epidemiological comments
After the HPAI outbreaks, all chickens and ducks in the infected farms and in the farms in a 3-km-radius area around them, were stamped out as a precautionary measure.
Movement restrictions on poultry were applied in the surveillance zone.
In order to investigate whether HPAI spread out into another zone or not, the surveillance will be enhanced all over the country.
First, all parent stock duck farms will be tested for HPAI and trucks which proved to stop by the infected farm have been traced as one of the disease control measures.
Country-wide serological tests on duck raising farms were conducted in collaboration with nine veterinary colleagues.
? Control measures
Measures applied Stamping out
Quarantine
Movement control inside the country
Screening
Zoning
Disinfection of infected premises/establishment(s)
Vaccination prohibited
No treatment of affected animals
Measures to be applied No other measures
? Future Reporting
The event is continuing. Weekly follow-up reports will be submitted.
