First Human Case of H5N5 Bird Flu Confirmed in Washington State

Olympia, Washington – A resident of Grays Harbor County has been diagnosed with H5N5 avian influenza, marking the first confirmed human case of this strain in the United States. The Washington State Department of Health reported that the patient, an older adult with underlying health conditions, was hospitalized in early November after experiencing severe symptoms, including high fever, confusion, and difficulty breathing.

This case is particularly significant as it is the first human infection with the H5N5 strain, which had previously only affected birds and mammals. While officials confirm the presence of the virus in this patient, they assure the public that the risk of transmission remains low. The patient has a mixed flock of domestic poultry at home, which had exposure to wild birds, and public health officials are investigating potential sources of infection.

Health officials state that there is no evidence of human-to-human transmission of the virus, and ongoing investigations will contact anyone who may have come into close contact with the patient. Dr. Scott Lindquist, the state epidemiologist, emphasizes the importance of caution but reassures that public health risks are minimal, stating, “We’ve never had human-to-human transmission.”

In recent months, Washington State has seen an increase in avian flu cases among wild birds and poultry, coinciding with a national rise in infections. Officials continue to monitor the situation closely. The Centers for Disease Control and Prevention is also actively tracking this case and any potential implications for public health.

The H5N5 strain was first detected in birds last year in eastern Canada and has since raised alarm among health officials due to its potential for mutation. As public health investigations proceed, officials aim to prevent any future spread of the virus among humans.
