Woman dies from bird flu strain new to humans in China

Chinese authorities said yesterday that a 73-year-old woman died after being infected with a bird flu strain that had sickened a human for the first time, a development that the WHO called “worrisome.”

China’s Center for Disease Control and Prevention confirmed the woman in the city of Nanchang had been infected by the H10N8 avian influenza virus, a strain that had not previously been found in people, the Jiangxi Province health department said on its Web site.

It is the second new bird flu strain to emerge in humans this year in China. In late March, the H7N9 avian flu virus broke out, infecting 140 people and killing 45, almost all of them in China.

The outbreak was controlled after the country closed many of its live animal markets — scientists had assumed the virus was infecting people through exposure to live birds.

Timothy O’Leary, spokesman for the WHO’s regional office in Manila, said WHO officials were working closely with Chinese authorities to better understand the new virus. He said though its source remains unknown, birds are known to carry it and it would not be surprising if another human case was detected.

“It’s worrisome any time a disease jumps the species barrier from animals to humans. That said, the case is under investigation [by Chinese authorities] and there’s no evidence of human-to-human transmission yet,” O’Leary said by telephone.

In the new case, the Jiangxi health department said the woman had severe pneumonia, before dying on Dec. 6 at a hospital in Nanchang.

She had suffered high blood pressure, heart disease and other underlying health problems that lowered her immunity, the health department said. Her medical history showed that she had been in contact with live poultry.

The health department said “no abnormalities” have been found in people who had close contact with her. It did not say if they had been tested or quarantined, though China has in previous outbreaks taken those measures.

Experts are cautious when it comes to avian influenza viruses infecting humans. They have been closely watching the H5N1 virus, which has killed 384 people worldwide since 2003.

The virus remains hard to catch, with most human infections linked to contact with infected poultry, but scientists fear it could mutate and spread rapidly among people, potentially sparking a pandemic.

Meanwhile, Taiwan issued a level 2 travel alert for Jiangxi Province yesterday.

“People traveling to Jiangxi should take health precautions and refrain from coming into contact with fowl,” Centers for Disease Control Deputy Director-General Chou Jih-haw (周志浩) said.

Epidemiologist Liu Yu-lun (劉宇倫) said Taiwan has asked China to provide the H10N8 genome sequence for comparison with that of a viral strain collected in Taiwan from wild bird feces.
