An individual has passed away following exposure to a virus previously confined to animals, raising concerns of a potential disease outbreak. The man was admitted to the hospital earlier this month after developing a high fever, which resulted in confusion and breathing issues.
Authorities were taken aback when the patient was diagnosed with H5N5, a subtype of avian influenza commonly carried by ducks, geese, and other wild birds. The Washington State Department of Health identified the patient as an “older” individual with pre-existing health conditions.
It was disclosed that the man maintained a variety of domestic poultry in his backyard in Grays Harbour County, situated in the southwest part of the US state. Upon examining the birds, officials detected traces of avian influenza, indicating that the patient likely contracted the virus from his own flock at home.
In contrast to H5N5, which is less common but distinct from H5N1 due to a surface protein variation, H5N1 has been infecting wild birds and domestic poultry since 2022. The US has recorded 71 human cases of H5 bird flu since last year.
While most individuals experienced mild symptoms, a fatal incident occurred in Louisiana this past January. On the other hand, the UK documented 81 instances of bird flu.
Confirmed cases have been noted in Cumbria, Lincolnshire, Norfolk, Suffolk, Scotland, and Wales.
Although regular flu and avian flu are caused by different viruses, they share common symptoms such as headache, muscle soreness, cough, and high fever. Severe cases may lead to pneumonia and acute respiratory distress syndrome.
According to the UK Government, individuals infected with the virus commonly exhibit red, sore, and discharging eyes.
In the UK, seven confirmed cases have been reported since 2021, all among individuals with prolonged exposure to numerous infected birds.
Dr. Robert Murphy, a professor specializing in infectious diseases and biomedical engineering at Northwestern University, warned of the potential for another pandemic, stating, “We have to be concerned because it could escalate into one.”
Despite the misconception that avian flu exclusively affects birds, it can also infect humans and other animals. Infected individuals are advised to self-isolate and receive antiviral medications like Tamiflu and Relenza.
Symptoms of avian flu in birds include a swollen head, blue discoloration around the neck and throat, and respiratory issues. People are cautioned against handling or coming into contact with sick or deceased birds.
In the UK, individuals infected with bird flu have either shown no symptoms or only mild ones. Testing is necessary to differentiate between regular flu and avian flu, as Dr. Murphy highlighted the virus’s high mutability and frequent mutations.
