Some 319,600 domestic birds have been culled within 3 kilometers of Shangxi Village, east China's Jiangxi Province, where a man was confirmed as the country's sixth bird flu case on Thursday.
The provincial government said the culled birds' shelters and farm tools and the area's affected roads and houses have been disinfected.
The area within 3 kilometers of Shangxi Village has been isolated, and 17 temporary animal inspection and quarantine stations have been installed to disinfect people and vehicles upon exit and entry.
Some 353,000 poultry in areas under threat of bird flu have been vaccinated, according to Jiangxi authorities. The patient, surnamed Guo, is a 35-year-old peddler from Shangxi Village of Quanjiang Town, Suichuan County.
He fell ill on December 4, having fever and pneumonia symptoms.
Specialists from the Chinese Ministry of Health also confirmed Guo's infection of the deadly avian flu strain.
Ninety-one people who had close contact with Guo have been sent to hospital for a week for medical observation. None of them has exhibited flu-like symptoms.
A preliminary diagnosis by the provincial veterinarian department pointed to an outbreak of bird flu among ducks reared in Gu's village. Local farmers have received informational materials.
