A Washington state resident has died after contracting a rare strain of avian influenza, H5N5, marking the first confirmed human fatality from this specific virus in the United States. The Washington State Department of Health confirmed the death on May 3, 2024, reporting the individual was the sole human case detected in the state thus far.
This case raises public health concerns as H5N5, while previously detected in poultry and wild birds, represents a potential for wider human transmission. The Centers for Disease Control and Prevention (CDC) is actively monitoring the situation and collaborating with state health officials to assess the risk to the general population and determine if further preventative measures are necessary. The fatality underscores the importance of vigilance regarding avian flu viruses, particularly as they evolve and potentially gain the ability to spread more easily among humans.
The deceased, an individual from Yakima County, was exposed to poultry. Symptoms began in late april 2024,and the infection was confirmed through laboratory testing. Health officials stated the person had limited contact with others, reducing the immediate risk of widespread transmission, but ongoing surveillance is crucial.
H5N5 is a subtype of the influenza A virus,commonly found in birds. While human infections are rare,they can occur through close contact with infected birds or contaminated environments. Symptoms in humans are similar to those of seasonal flu, including fever, cough, sore throat, muscle aches, and respiratory difficulties.
Prevention Tips:
* Avoid contact with wild birds and poultry: Do not handle sick or dead birds.
* Practice good hygiene: Wash hands frequently with soap and water, especially after being outdoors or near birds.
* Cook poultry thoroughly: Ensure poultry is cooked to an internal temperature of 165°F (74°C).
* Report sick birds: Contact your local animal health authorities if you find sick or dead birds.
* Consider vaccination: While a specific H5N5 vaccine isn’t available, annual flu vaccination can offer some protection and reduce the risk of co-infection.
The CDC advises anyone experiencing flu-like symptoms after potential exposure to birds to seek medical attention immediately and inform their healthcare provider about the exposure.Further updates and guidance will be provided as the investigation progresses.
