First Human Death from H5N5 Bird Flu Reported in Washington
A Washington state resident has become the first person to die from the H5N5 strain of bird flu, according to health officials. The individual, who lived in Grays Harbor County, was hospitalized earlier this month in Kings County, where Seattle is located.
Key Details About the Case
- The patient was an older adult with underlying health conditions
- Symptoms included high fever, confusion, and breathing difficulties
- The person maintained a backyard flock of mixed domestic poultry
- Virus was detected in the flock’s environment, indicating animal exposure as the likely source
Health officials have not released the person’s name, age, or gender. The Washington State Department of Health is monitoring other individuals who were exposed to the infected flock.
About the H5N5 Virus
This marks the first human infection ever recorded with the H5N5 strain. The virus first appeared in 2023, affecting birds and mammals in eastern Canada. Research published last year revealed that some infected animals carried a key mutation that allows the virus to transfer more easily between mammals.
Pandemic Concerns and Monitoring
Epidemiologists and virologists express concern that avian influenza could potentially generate a pandemic if allowed to spread and mutate. The H5N1 virus currently circulating in North American dairy cattle, for instance, is considered just one mutation away from being able to spread easily between people.
Health officials emphasize that the risk to the general public remains low. No other individuals have tested positive for avian influenza, and there is no evidence of human-to-human transmission. Authorities continue to monitor anyone who had close contact with the patient.
