US Reports First Human Death from Rare Bird Flu Strain H5N5, CDC Says Risk is Low
The US has reported its first human death from a rare strain of bird flu, H5N5. The victim, an older adult with underlying health conditions in Washington state, had been hospitalized since early November with symptoms including high fever, confusion, and respiratory problems.
According to the Washington State Department of Health, the man's infection was linked to his backyard flock of domestic poultry that had come into contact with wild birds. Health officials have said that no other individuals have tested positive for avian influenza after coming in close contact with him.
While concerns over the risk of transmission between people are low, state health officials will continue to monitor anyone who came into contact with the man. This is due to the fact that there is currently no evidence of virus transmission between humans, according to the Centers for Disease Control and Prevention (CDC).
H5N5 is considered not to be as dangerous to human health as H5N1, which has been linked to 70 reported human infections in the US over the past two years. Most cases of H5N1 have resulted in mild illnesses among farm workers.
The key difference between H5N5 and H5N1 lies in a protein that is involved in releasing the virus from infected cells and spreading it to surrounding cells. This distinction suggests that H5N5 is not significantly more deadly than its counterpart, at least according to current data.
