Highly pathogenic avian influenza (AI) is spreading at a very rapid rate in poultry farms such as chickens and ducks across the country, causing an emergency in quarantine authorities and poultry farms.
The Central Avian Influenza Accident Control Center announced on the 15th that a total of three cases of highly pathogenic avian influenza (AI) were confirmed in Imsil, Jeollabuk-do, Cheonan, Chungnam and Gumi, Gyeongbuk.
In the case of Imsil, Jeollabuk-do, a suspicious report was filed on the 14th due to increased mortality at the broiler breeder farm. In addition, a virus was found at a broiler farm in Gumi, North Gyeongsang Province, during an inspection of the slaughterhouse.
All three cases were confirmed as highly pathogenic H5N8 avian influenza as a result of close examination.
An official at the heavy water plant said: “If the quarantine status of the poultry farm is at least a little insufficient, the risk of highly pathogenic AI is high.” Be sure to practice this, and carefully review and save the disinfection certificate for the vehicle visiting the farm. “
Meanwhile, the broiler farm in Chungju, Chungbuk, where a suspected AI was reported on day 15, is likely to be low pathogenic with low risk of spread.
As a result of a close examination of a positive liver sample collected from a broiler farm in Haguam-ri, Jungangtap-myeon, Chungju-si that day, the H9-type antigen was detected. Unlike the highly pathogenic avian influenza virus, which kills more than 80% of chickens within 1 to 2 days when infected, the low pathogenicity has virtually no serious effects.
In the case of highly pathogenic AI, the type H5 or type H7 antigen mainly comes out. The final hypophatic state is expected to emerge in about a week.
