Bird Flu Kills Man in Thailand's First Human Case in 7 Months
July 26 (Bloomberg) -- Bird flu killed a man in northern Thailand yesterday, the first case reported in seven months in the world's fourth-biggest poultry exporter.
The man from Phetchabun province, about 350 kilometers (218 miles) north of Bangkok, tested positive for the H5N1 avian flu virus, Prime Minister Thaksin Shinawatra told reporters in Bangkok today. Part of the province has been declared a "red zone'' -- the highest level of H5N1 alert, Thaksin said.
Human H5N1 fatalities have almost tripled this year as the virus spread in wild birds and domestic poultry to at least 38 countries. New cases create chances for the pathogen to mutate into a pandemic form that may kill millions of people. The previous H5N1 outbreak in Thailand was in November and the last of the country's 22 human cases was reported in December.
During the past three years, H5N1 has infected at least 231 people in 10 countries in Asia and the Middle East, killing 133. This year, 57 fatalities have been reported to the Geneva-based WHO, compared with 20 in the first seven months of 2005.
The virus was first reported in Thai poultry in January 2004 and killed 14 people in the Southeast Asian nation over the following 23 months.
Thailand's health ministry had 18 human flu cases, including two in Phichit, under surveillance as of July 20, the Bureau of General Communicable Diseases said on its Web site. Six other cases were from Suphanburi, five from Phetchabun, two from Sukhothai, and one each from Sakaew, Uthaithani and Ayutthaya, it said.
Poultry Outbreak
Thirty-one chickens died of avian flu in the northern province of Phichit in an outbreak that began on July 16, Yukol Limlamthong, Thailand's director general of livestock, told the World Organization for Animal Health July 24. The government is culling fowl and disinfecting surrounding areas, he said.
Tests showed the fowl had a highly pathogenic H5 subtype of avian flu. More tests were being conducted to establish whether it was H5N1.
More than 209 million poultry have died or been culled worldwide since January 2004 because of H5N1, the Food and Agriculture Organization of the United Nations said in a June 19 report.
Reports of human cases have tended to be highest during the cooler periods in the Northern Hemisphere, the WHO said in its June 30 issue of the Weekly Epidemiological Record. If this pattern continues, an increase in cases could be expected starting in late 2006 or early 2007, the report said.
