A total of 26 suspected human bird- flu cases were being closely watched in Thailand's northern province of Phitsanulok since they fell sick after contacting with dead birds, the chief public health officer of the province said Friday.
Thawatchai Kamoltham, chief Phitsanulok public health officer, said 15 of the 26 people whose symptoms are similar to those of the deadly H5N1 bird flu virus were officials taking part in culling infected fowls.
The rest were villagers from three districts of Muang, Wat Bote and Bang Rakam, Thawatchai was quoted by Thai news group The Nation as saying.
However, only three of the 26 have been admitted to hospitals while the rest were being closely monitored at their home, the report said.
Local health authorities had declared a duck farm in Tortae sub- district of Phitsanulok off-limits for two weeks as a precaution. About 600 ducks in the farm have been slaughtered. It is also reported that there are also about 30 pigs in the province which may have contracted bird flu.
