First Human Death from Unseen Virus Strain
A Washington statea resident has been the first individual globally to pass away due to aa virus strain that has not been encountered in humans previously.
The individual, an elderly person with pre-existing health issues, was admitted to the hospital due to avian-related illness.fluearlier this month, following a high fever, confusion, and significant respiratory issues, officials stated.
Laboratory tests verified that the patient had contracted H5N5, a type ofbird fluobserved in animals previously but not documented in humans before.
The individual who succumbed to the virus kept a collection of various domestic birds in their backyard.
They were initially seen by physicians in Grays Harbor County, approximately 100 miles west of Seattle, and then moved to a undisclosed hospital in King County within the Seattle region for specialized treatment.
They were reported to be in 'critical condition' prior to their passing.
"The public risk is still minimal. No other individuals connected to the case have tested positive for avian flu," stated the Washington State Department of Health in a release.
Health authorities will keep tracking individuals who had close contact with the patient for any signs to confirm that the virus has not spread from person to person. There is currently no indication of human-to-human transmission of this virus.
More information regarding the patient, such as their name, sex, age, and therapy, was not disclosed.
It remained uncertain how the person became infected, although authorities suggested it was probably connected to contact with wild or domesticated birds.
Bird flu was identified in the patient's backyard chickens, suggesting it is the probable source of the illness.
Two birds in their group passed away due to an unknown disease a few weeks back, while the remaining birds are currently in good health.
Authorities have contacted people who came into contact with the patient and tested those showing symptoms. No additional cases of avian flu were found by Friday, according to officials.
It is possible to contract the virus following exposure to the saliva or waste products of infected birds, or by coming into contact with the body of a bird that succumbed to the virus.
Where the strain could be identified, all prior human cases have beeninfected with the H5N1 strain.
Experts noted that the emergence of this strain in humans highlights the virus's 'unpredictable' development. Nevertheless, there is currently no indication that this variant is more contagious or causes more severe illness in humans compared to other forms of the virus.
This case represents the initial occurrence of avian influenza infectionfound in the United States for a minimum of eight monthsand the first one documented in Washington state this year.
Since the avian influenza outbreak started in January 2022, a total of 71 people have been affected, and one person, a person in Louisiana, has passed away. Only four instances have been identified this year so far.
Authorities have emphasized, nevertheless, that the danger to the general population is still minimal. Dr. Beth Lipton, the state's public health veterinarian, stated during a press briefing: "H5N5 is not a novel strain or entirely new virus. It is simply the first instance we are aware of where it has affected a human."
Health officials from the Washington State Department of Health disclosed the presence of a new virus strain during a press briefing on Friday.
Dr. Angela Rasmussen, a virologist based in Canada, stated on X: 'It's not H5N1, but H5N5, which doesn't offer me any comfort. This is a reassortment that has resulted in a hospitalization. It's highly unpredictable.'
I trust that epidemiologists are conducting studies to determine who else may have been exposed, so that suitable outbreak investigation and control measures can be implemented.
Dr. William Schaffner, an expert in infectious diseases based in Tennessee, statedNewsweekInfection by the H5N5 avian influenza virus is probably an uncommon occurrence with limited effects on the general population.
Since the avian influenza outbreak started in 2022, the majority of cases have occurred in California, which has reported 39 confirmed or suspected bird flu infections, or Washington, where therethere were 15 confirmed or suspected cases of avian influenza.
In the majority of instances, infections have been associated with contact with infected household birds or milk-producing cattle, which themselves have been affected by the virus.
In wild and domesticated birds, avian influenza has now beenfound in all states across the US since January 2022.
Approximately 174 million wild and domestic birds are believed to have been impacted, along with over 1,000 dairy herds that have also been affected.
Since September of this year, it has affected 7 million farmed birds across the country, including 1.3 million turkeys, raising worries about a potential shortage for Thanksgiving.
Authorities caution that bird flu infections tend to increase during this season as wild birds, which might harbor the virus, travel, possibly transmitting the virus to different regions.
Some worries persist that the virus might transmit to humans and acquire the ability to spread among them, potentially leading to a new outbreak akin to the Covid pandemic.
The CDC states online that the danger to the public from avian flu is still minimal.
It states online: 'H5 avian influenza is prevalent among wild birds across the globe and is leading to outbreaks in poultry and US dairy cattle, with several recent human cases reported among workers in US dairy and poultry facilities.'
Although the present public health threat is minimal, the CDC is closely observing the situation and collaborating with states to track individuals who have had contact with animals.
'CDC is utilizing its influenza monitoring systems to track H5 avian flu in humans continuously.
