Yikes! #H5N1 virus re-emerges in European mammals

#Foxes in #Norway and #Slovenia are among the latest victims of the virus.

Jackie Linden, December 27, 2024

"Over the past week, notifications from national veterinary authorities have recorded that wild mammals have tested positive for the highly pathogenic avian influenza (#HPAI) virus in two geographically distant European states.

"Based on reporting to the World Organisation for Animal Health (#WOAH), Europe had been free of HPAI infections since June of 2024.

"Earlier this month, in Central Europe, a fox found dead in Slovenia tested positive for the H5N1 virus, according to the official notification.

"Around one week ago, the #H5N5 virus serotype was detected in a #lynx (#Wild Cat) found dead in northern Norway.

"In February of this year, two dead foxes tested positive for the same virus variant in the same Norwegian county. The disease situation was declared 'resolved' by the Norwegian animal health agency six months ago."

Update: The patient has died.

"Concerning" #BirdFlu mutations in Louisiana patient underscores #pandemic potential of #H5N1

By Nicole Karlis, Published December 31, 2024

"In 2024, at least 66 human cases of bird flu have been reported in the United States, each one raising the risk of another pandemic like COVID-19. So far, most cases have been described as 'mild,' which means they weren't hospitalized. No patients have died, though infections years ago had a very high mortality rate. Symptoms have typically included #PinkEye, but not serious respiratory distress.

"However, a patient recently made headlines in Louisiana for being a more severe case. The patient, who is reportedly over the age of 65, was hospitalized and in critical condition due to severe respiratory symptoms.

"Last week, the U.S. Centers for Disease Control and Prevention (CDC) said a genetic analysis suggests the virus mutated inside the patient to possibly make it a more severe illness in humans. The agency called the mutation 'concerning,' as it may allow the virus to better bind to receptors in humans' upper airways. This would make it easier to jump from person to person, sparking major outbreaks or even a pandemic. However, the public health agency said that the risk to the general public from the outbreak 'has not changed and remains low.' ['Cuz, shop till you drop!]

"The CDC also stated that these mutations HAVE NOT [emphasis mine] been detected in the bird flock that infected the patient, which would make the situation 'more concerning.' [Just like the case in British Columbia]

"'These changes would be more concerning if found in animal hosts or in early stages of infection (e.g., within a few days of symptom onset) when these changes might be more likely to facilitate spread to close contacts,' the CDC said in its report. 'Notably, in this case, no transmission from the patient in Louisiana to other persons has been identified.'"

Canadian teen with #BirdFlu was on #LifeSupport, new report reveals

The hospitalized teen was also given three #antiviral treatments, underscoring how severe #H5N1 infection can be

By Nicole Karlis, January 6, 2025

"In November, a teenager in British Columbia was infected and hospitalized with bird flu, caused by the H5N1 virus. While most cases have been mild, commonly characterized by #conjunctivitis and respiratory symptoms, this previously healthy Canadian teen was hospitalized from the virus in critical condition. Their symptoms started with double conjunctivitis, also known as pink eye, and turned into a fever and coughing. A few days later the teenager was admitted to intensive care after developing acute respiratory distress syndrome [#ARDS].

"'This was a healthy teenager prior to this, so no underlying conditions,' said British Columbia’s health officer, Bonnie Henry, at a news conference at the time. 'It just reminds us that in young people this is a virus that can progress and cause quite severe illness.'

"Now, a recent report brings to light more details about the teenager’s case. In the report, published in the New England Journal of Medicine (NEJM), researchers explain that the 13-year-old girl spent weeks fighting for her life after contracting a severe H5N1 infection from an unknown source. In finding her diagnosis, researchers say that she initially tested positive for influenza A, but not the seasonal subtype. Further testing suggested she had a high viral load of a novel influenza A infection, which researchers discovered to be the H5N1 avian flu.

"The next day doctors started her on oseltamivir, also known under the brand name Tamiflu. However, her respiratory functions declined rapidly causing her to be intubated. She was also placed on extracorporeal membrane oxygenation (ECMO), a machine that is a form of life support for people with life-threatening illnesses. In addition to the ECMO machine, the teenager received a plasma exchange and two more antiviral medication treatments — amantadine and baloxavir.

"In an accompanying editorial, experts noted while mutations were detected in her case, it’s 'unclear whether these #mutations were present in the infecting virus or emerged during the course of the patient’s illness.'

"In other words, it’s unclear if the virus #mutated to be more severe in humans.

"'The mutations evident in the Canadian case highlight the urgent need for vigilant surveillance of emerging mutations and assessment of the threat of human-to-human transmission,' the editorial stated, adding that vaccine development and therapeutics are also needed — perhaps to treat more severe illness. 'The Canadian case showed higher viral loads in the lower airway and very prolonged shedding, despite therapy, which highlights the potential need for longer therapy.'

"Researchers concluded their editorial with an acknowledgment that 'many questions remain.' For example, the severity of cases is likely to depend on host immunity, the route of exposure, or other changes in the virus.

"Currently, the CDC says that the risk to most Americans remains low.

"'We do have candidate vaccines and antivirals available to try to mitigate severe influenza in the case of wider spread,' the report stated. 'That said, a balance between enhanced vigilance and ‘business as usual’ is needed."
