Hospital officials in the Indonesian capital, Jakarta, say a 37-year-old woman has died of bird flu, bringing the country's death toll from the disease to 59.

The officials say the woman died Thursday after being diagnosed with the H5N1 bird flu strain earlier this week.

Also Thursday, health officials in South Korea said a person there contracted bird flu but has no symptoms of the disease. They said the person was infected during an outbreak of the potentially deadly H5N1 strain that hit poultry farms late last year.

And in Japan, officials are investigating a possible outbreak at a chicken farm in Miyazaki Prefecture. The farm feeds about 10,.000 chickens.

The H5N1 strain of bird flu has killed more than 150 people worldwide over the past three years -- none in Japan or South Korea.
