Nou cas humà mortal de #gripaviaria #H5N1 #HPAI a #Cambodja. Ja porten 4 aquest any (i un total de 6 al món). Infant de 11 anys d'edat. Tot apunta a transmissió des d'aus de corral infectades en explotació traspati.
Via normal de transmissió, conseqüències conegudes.
Si jo fos un #virus maligne (no tenen voluntat, és impossible) ara circulant no deixaria de batre palmes. No s'evita la meva transmissió (per vaques), la vigilància no és intensiva, no es controlen (massa) els casos en humans, productes q em contenen (#lletcrua) es venen sense cap limitació i es cancelen linies d'investigació en vaccins contra la meva circulació (veure https://statnews.com/2025/05/28/moderna-flu-vaccine-development-cancelled-by-hhs-mrna-platform-offers-speedy-pandemic-response/).

As #BirdFlu wreaks havoc in the Midwest, researchers say #vaccines offer a way out
Researchers say vaccinating poultry is crucial for reining in H5 and reducing the stress on farmers and consumers hit by high egg prices. Vaccination could also help reduce the number of infections and the threat of a pandemic.

Excerpt: "Spring and fall bird migrations could add to bird flu threat
"Spring and fall bird migrations could add to the H5 threat as birds congregate in areas near farms and mix with waterfowl, which are key hosts for the virus.
"In the Great Lakes region, a combination of migratory bird flyways, waste grain missed during harvest, and abundant lakes and reservoirs attracts large numbers of migrating birds—and potentially high levels of avian flu virus, says Matthew Hardy, a waterfowl ecologist and co-founder of #AgriNerds, a company that tracks bird movements to help farms prevent outbreaks.
"Hardy pointed to Darke and Mercer counties in northwest Ohio, near Dayton, as areas where some of these factors may have contributed to major outbreaks in poultry facilities in late 2024 and early 2025.
" 'There’s going to be continued outbreaks and likely mass die-offs in places where birds stage,' Hardy said, referring to the areas where birds come together and rest during migration.
"Wetland loss could make this issue worse, pushing birds closer to farms.
"Changing temperatures, weather patterns, and human activity have driven the loss of natural wetlands that waterfowl and other species depend on, Hardy said. This has brought them closer to farms as they search for food and suitable habitat. The rate of wetland loss, primarily driven by agriculture, has increased in recent years in the Upper Midwest, Grist reports.
"Cardona, with the University of Minnesota, said fall may pose a more significant threat for disease spread than spring. Birds flying north in spring often have some immunity from exposure to viruses the previous year. But those hatched in fall don’t have immunity and may be more vulnerable and likely to spread the virus, especially in the Upper Midwest.
" 'The birds are breeding and propagating up near the Arctic Circle or in colder areas … As they fly south, those birds mix and mingle and share and reassort viruses,' she said.
"Birds develop antibodies on their southward migrations, reducing the amount of virus they shed over time, Cardona said. This could explain why so many H5 outbreaks occurred in the upper part of U.S. flyways in states like Minnesota, Michigan, and the Dakotas, which also have large numbers of turkeys and laying hens that are especially susceptible to H5.
"She emphasized the difficulty of making predictions about H5.
" 'The only predictable thing about influenza is that it’s entirely unpredictable,' she said."

Cross post from my veterinary account. Yeah, it really is *that* important and I needed a spot with more character allowance...
Serious post here about Avian Flu, based on what I'm encountering in my field work and the word among my colleagues who are more closely involved in the field. Please read on and act.
Remember when Trump dismantled the pandemic preparedness office in 2018, just a couple years before COVID hit. Remember? HELLOOOO! Remember? Don't forget, because now his administration is dragging their heels on staffing that office. Right in the face of a global pandemic of highly pathogenic avian influenza (HPAI). It has showed up about every 10y the past few decades, but this time it didn't go away. Moreover, it jumped into mammals with impunity. It's even affected people but, thankfully, so far hasn't spread from person to person. But it can, and probably will. This is not hyperbole. This is not "what if." This is NOW. While we are distracted by bread and circuses, and RFK is wasting time conjuring epidemics where they don't exist, the veterinarians and virologists on the front lines are shitting their pants seeing the real epidemic that's taking place. Folks, if this moves into a global pandemic of HPAI moving among people, it WILL disrupt everything so fast that there'd be no way to start responding effectively from scratch. Millions would die, needlessly. We need more labs, more expertise, not DOGE fumble fucking around interrupting the work. And we need a department that coordinates it and prepares us for the catastrophe that IS coming. Maybe we'll get super lucky and it won't happen this time, but HPAI is here to stay so it won't be wasted effort. Get on your government reps, state and federal, and demand that they take this seriously. Otherwise, all this anthropic bullshit they think is so important, well, you can kiss it all goodbye.

#RedFox 1st mammal in #Virginia to test positive for #AvianInfluenza
Culpeper Star-Exponent Apr 17, 2025
"Blue Ridge Wildlife Center recently admitted an adult female red fox from the Town of #HamiltonVirginia, in Loudoun County, that tested positive for Highly Pathogenic Avian Influenza. This is the first report of an #HPAI positive mammal in Virginia, according to a news release from the nonprofit rescue in Boyce, Clarke County.
"On intake March 31, the animal was not responding to handling.
" 'She was also exhibiting tremors and nystagmus, a rhythmic, involuntary eye movement that is often seen with brain trauma or disease. Given these severe neurological signs without any indication of trauma, our top differentials were rabies, distemper, and HPAI.'
"As all of these diseases have a very poor prognosis, humane euthanasia was elected. Rabies testing came back negative, the center said. Brain tissue samples again confirmed HPAI suggesting it as the primary cause of the clinical signs this fox was exhibiting, according to an April 8 update.
"Though a first for Virginia, many other states have seen many mammalian positives, especially in dairy cows and free-roaming domestic cats.
" 'With cases on the rise at our hospital, and foxes having been found positive in multiple nearby states, this case did not come as a surprise, according to the Blue Ridge Wildlife Center statement. “This positive was of course reported to the proper authorities and those that came into contact with the fox are actively monitoring for HPAI signs, which include fever, body aches, and irritated eyes in humans.'
"The center requested the public help minimize the risk of this virus by keeping a respectful distance from wildlife. Most cats are infected by hunting wild prey or ingesting raw meat or milk, so pets should not be allowed to free roam or be fed raw milk or meat products.
" 'This virus is still considered low risk to humans and there is no need to be concerned as long as you are staying up to date on the outbreak through reliable sources and taking proper precautions around wildlife and susceptible domestics,' the center stated."

#BirdFlu Has Now Been Discovered In Several Species Of #Texas Wild Mammals
by Renee Raven
Published: April 21, 2025
"#AvianFlu, a.k.a. Bird Flu or HPAI, has recently been discovered in several species of wild mammals, according to the Texas Parks and Wildlife Department (#TPWD).
Which Texas Animals Are Infected With Bird Flu?
"This highly contagious pathogen has been found in several mammalian species, including #foxes, #raccoons, striped #skunks, and #DomesticCats.
Where Has Bird Flu Been Found In Mammals In Texas?
"#DeafSmith, #Hansford, #Lubbock, #Ochiltree, #Parmer, and #Randall Counties all had mammals test positive for bird flu. This will likely spread to other counties.
What Impacts Will Bird Flu In Mammals Have?
"Needless to say, this could cause a devastating impact on both wild and domesticated animals and birds, including pets and backyard chicken coops.
How Are Mammals Becoming Infected With Bird Flu In Texas?
"The wild mammals are primarily becoming infected through eating the corpses of birds that died from the flu (so outdoor #cats are at a high risk), however, mammal-to-mammal spread is possible."
