Two more Indonesians have died from bird flu, a health official said Saturday, pushing the toll this week to four in the latest cases to strike the country worst hit by the virus. The cases underscore the threat posed by the virus in Indonesia, which was affected by H5N1 when it first appeared in poultry stocks and among backyard chickens in 2004, the Associated Press reported. One of the two latest victims was a 22-year-old woman who died early Saturday while the other victim _ also a woman _ died late Friday, said Nyoman Kandun, the Ministry of Health's director general of communicable disease control. The deaths bring Indonesia's tally of human fatalities to at least 61 _ more than a third of the world's total.
