The first human case of bird flu in seven years has been diagnosed in Hong Kong, health officials said Thursday, urging the public to take precautions.
A 59-year-old woman was hospitalized in serious condition after a trip to mainland China, the Hong Kong Department of Health said.
Her illness was diagnosed as influenza A (H5), a variant of bird flu. It was unclear where she had contracted the disease. She did not have any contact with live poultry and did not visit farms while in China, Hong Kong health officials said.
