A 27-year-old Thai man has died of bird flu, the country's second death this year, officials said on Saturday, as they put eight more provinces, including the Bangkok area, on a bird flu watchlist.
The man died on Thursday after the H5N1 virus killed chickens on his backyard farm in the province of Uthai Thani, 220 km (135 miles) north of Bangkok, the third province to suffer an outbreak since the virus re-emerged in July after an eight-month lull.
The World Health Organisation, which says bird flu killed at least 134 people world-wide before the latest Thai death, urged previously hard-hit countries to be vigilant.
