Taiwan has confirmed the country’s first case of the highly pathogenic H5N5 strain of avian influenza on a duck farm in Cishan District, Kaohsiung, Council of Agriculture (COA) Deputy Minister Huang Chin-cheng (黃金城) said Monday.
The virus was identified Sept. 12 as an H5 subtype and was confirmed as H5N5 the following day. The case has been reported to the World Organization for Animal Health (OIE), according to Huang.
According to OIE regulations, H5N5-free status can be regained if no new cases are detected within three months of preventive measures and surveillance, including disinfection of all affected establishments, Huang said.
It is hoped that the surveillance plan can be completed during the three-month period from Sept. 12 to Dec. 12, he added.
The H5N5 case was the first in Taiwan but was not the first in Asia. The first H5N5 virus in Asia was detected in China in 2011, according to the COA.
However, the source of the virus is still unknown, according to Huang.
The virus detected on the Cishan duck farm led to the culling of 3,583 ducks, according to Tu Wen-chen (杜文珍), deputy chief of the COA’s Bureau of Animal and Plant Health Inspection and Quarantine.
Rapid diagnostic tests for detecting the highly pathogenic virus were conducted on five nearby farms, all of which showed negative results, meaning that the virus has not spread to other areas, Tu said.
High-risk areas for avian flu outbreaks in Taiwan are mainly in 18 townships in Changhua, Yunlin and Pingtung counties, as well as Tainan and Kaohsiung.

A farm in southern Taiwan had to cull 5,119 ducks after a sample tested positive for the H5N2 strain of avian influenza.
Liberty Times reported Monday (Sept. 9) the outbreak occurred at a duck farm in Wandan Township, Pingtung County, according to the city’s Animal Disease Control Center. Birds affected with the highly-pathogenic virus strain do not usually appear ill – hence, infection is determined through sampling.
Sterilization measures have been taken at the poultry farm and in the surrounding areas following the outbreak. Monitoring work will be enforced within a 1-kilometer radius of the affected duck farm, the center said.
Animal health authorities urged the island’s poultry farmers to avoid free range husbandry, so as to reduce the chances of bird flu spreading. They were also urged to report any irregularities so the disease can be effectively controlled.

Vietnam’s southern Ba Ria Vung Tau province has seen first outbreaks of A/H5N6 bird flu which have led to the culling of 10,500 chickens, local media reported on Tuesday.
The outbreaks were spotted in two communes in Xuyen Moc district on July 31 and Aug. 1, and then tests confirmed that some chickens were infected with the bird flu virus, Vietnam News Agency quoted the provincial Department of Livestock and Animal Health as reporting.

The bird flu is forecast to widely spread in the remaining months of this year due to changing weather and surging poultry transportation in time ahead of the lunar new year holiday.
Vietnam first detected bird flu virus strain of A/H5N1 in December 2003 on both humans and fowls. More than 45 million poultry in Vietnam were culled between 2003 and 2006. Since then, hundreds of thousands of fowls have been killed each year.
