Indonesia on Friday confirmed its fourth human death from the bird flu virus, taking the death toll in Asia to 63, and said it was investigating whether a neighbor of the victim was also sickened by the disease.
Tests from a Hong Kong laboratory showed that a 37-year-old woman who died last week had contracted the H5N1 bird flu virus, said I Nyoman Kandun, the health ministry's director general for illness control and environmental health, the AP informs.
The health ministry also said that a neighbor of the woman had been hospitalized with symptoms consistent with bird flu. But authorities said they were still awaiting lab results before confirming she had been sickened by the virus.
Kandun warned that Indonesia would continue to report cases because the virus was rife in poultry farms across the country. "It will be like in Vietnam and Thailand," he told The Associated Press.
The virus has swept through poultry populations in large swathes of Asia since 2003, resulting in the deaths of tens of millions of birds, and 63 people, most of them in Vietnam and Thailand.
Indonesia recorded its first human fatalities from bird flu in July when a father and his two daughters died after contracting the virus. Officials have linked those deaths to droppings from an infected bird.
Kandun said the source of the latest infection was not yet known.
He said surveillance of poultry needed to be stepped up, but urged the country's 210 million people not to panic.
"Be alert, but do not be alarmed," he said.
Officials have carried out limited vaccinations of some of the estimated 2 billion birds in the country, but say they lack funds to carry out culls of flocks in areas where the virus is prevalent.
The virus has been recorded in 22 of Indonesia's 32 provinces since 2003.
Most of the human deaths from bird flu have been linked to contact with sick birds. But the World Health Organization has warned that the virus could mutate into a form which is more easily transmitted from human to human, possibly triggering a pandemic that could kill millions worldwide.
