First Human Case of H5N5 Bird Flu Detected in Washington State

A Washington state man is the first person ever infected with the H5N5 bird flu strain. The man was hospitalized earlier this month with severe symptoms. He lives in Grays Harbor County on the Pacific coast.

State health officials confirmed the case. The patient is older and has underlying health conditions. He also kept a backyard flock of poultry at his home.

Details of the Groundbreaking Infection

The man became severely ill in November. According to reports from the New York Post, he suffered a high fever and confusion. He also experienced serious respiratory distress.

The Washington State Department of Health led the investigation. Officials noted the man’s domestic poultry flock. Two birds from his flock had recently died.

This case is a significant alert for epidemiologists. It shows the virus can jump to humans. Continued vigilance in animal and public health is crucial.

This first human infection with the H5N5 bird flu underscores the evolving nature of avian viruses. Health officials stress that public risk is currently minimal. However, the event highlights the need for ongoing surveillance of animal diseases.
