"A Washington resident who was the first human case of bird flu in the U.S. since February died on Friday, state health officials said. The person was an older adult with underlying conditions and had been hospitalized since early November with a strain that was previously reported in animals but never before in humans.
The person had been undergoing treatment for infection with H5N5 avian influenza, the health department said in a news release. State epidemiologist Scott Lindquist said last week that the person, who was hospitalized after developing high fever, confusion and respiratory distress, was “a severely ill patient.”
State officials said the risk to the public remains low. No other people involved have tested positive for influenza, and public health officials are continuing to monitor anyone who was in contact with the patient — including more than 100 health care workers — for symptoms to ensure that human-to-human spread has not occurred, the health department said."
