#CDC confirms that a California child with no known exposures to infected animals or poultry somehow contracted #H5N1 #birdflu.


“The world cannot afford to gamble with this (bird flu)virus, letting it spread in animals & hoping it never sparks a serious outbreak.

I hope we are not watching the start of a new pandemic unfold…”- Dr Oliviera

Time is of the essence: #effectiveness of dairy #farm #control of #H5N1 is limited by fast spread

Abstract
The emergence and growth of highly pathogenic avian influenza(HPAI) A(H5N1) in dairy cows poses a growing threat for both the food supply and onward zoonosis to humans. Despite ongoing surveillance and control measures recommended by animal and public health authorities to limit viral spread, new herds continue to report infections. We show here that the continued spread between farms could be explained by the rapid pace of pathogen spread reported within farms, which greatly limits the potential effectiveness of these recommendations. Under reasonable surveillance strategies, we show that the time farms have to mobilize interventions is extremely limited, as few as a couple days and typically less than a week. Our findings suggest that passive surveillance measures, such as detection of H5N1 via weekly bulk milk testing, comes too late such that most infections have already occurred. For current interventions to be valuable, more sensitive and extensive surveillance is needed and an emphasis should be placed on biosecurity practices rather than reactive practices.

#USDA has confirmed 3 more #H5N1 #birdflu infected dairy herds in California, bringing the state's total to 294, nearly 27% of herds in the state. All those herds were recorded in the past 2.5 months.

The cumulative national total is 508 herds across 15 states. https://www.aphis.usda.gov/livestock-poultry-disease/avian/avian-influenza/hpai-detections/hpai-confirmed-cases-livestock

«Wer tote Wasser-, Raben- oder Greifvögel findet, sollte den Fund der zuständigen Veterinär- und Lebensmittelaufsicht des Bezirks melden, damit eine Untersuchung veranlasst werden kann.» Kranke oder verendete Tiere sollten auf keinen Fall angefasst & Federn nicht gesammelt werden.
Geflügelhalter würden gebeten, ihre Tiere jetzt vor dem Kontakt mit Wildvögeln zu schützen.

"Die Weltgesundheitsorganisation (WHO) betont die Notwendigkeit internationaler Zusammenarbeit, um das Risiko einer möglichen Pandemie zu minimieren. Durch Impfungen und strikte Überwachungsmaßnahmen kann die Ausbreitung der Vogelgrippe eingedämmt werden."

"Warum der kanadische Jugendliche so schwer erkrankte, ist offen. Bonnie Henry hält es Medienberichten zufolge für möglich, dass das junge Alter des Patienten eine Rolle spielte. Womöglich hätten Erwachsene, die früheren saisonalen H1N1-Grippeviren ausgesetzt waren, einen teilweisen Schutz gegen den aktuellen H5-Stamm."

Update on the Canadian teen who contracted #H5N1 #birdflu:
I spoke today with Bonnie Henry, British Columbia's health officer. She expressed cautious optimism that the lack of additional cases suggests this may have been a one-off event. https://www.statnews.com/2024/11/13/bird-flu-canada-teenager-infected-different-strain-than-dairy-cattle/


“Very concerning severe case of bird flu in a Canadian teen.

We need leadership now to prepare for a potential #H5N1 pandemic.”— Rick Bright

Infektionsrate: 7%

"Forscher fürchten, dass sich das #Virus besser an Säugetiere anpassen kann, wenn es verbreitet in ihnen zirkuliert. Eine #Studie zeigte im August eine Übertragung von Säugetier zu Säugetier, auch zwischen Tierarten, etwa von Kühen auf Katzen. Mutationen des Virus, die zu einer verbesserten Übertragbarkeit von #H5N1 auf den Menschen führen würden, wurden bisher nicht entdeckt"

"degradation of PPE is not uncommon when workers are in close proximity to contaminated milk or animal manure"

I did think ethanol degrades electret respirators (N95s) but is soured milk really offgassing so much?

And proximity to manure - does methane or something degrade electret material?

"with almost any infectious disease, but especially one that is respiratory in nature, asymptomatic cases of infection are “absolutely anticipated.”"

"“We will have a bird flu pandemic,” Robert Redfield, former director of the CDC, bluntly predicted in a television interview in June. “It’s not a question of if; it’s more a question of when … Once the virus gains the ability to attach to the human receptor and then go human to human, that’s when you’re going to have the pandemic.”"

strong words from a person who doesn't need to mince to keep a job

"“I don’t think it’s a foregone conclusion that H5N1 is going to be the cause of the next pandemic,"

says someone with a John Hopkins job to lose.

"“It can be probably hard to use a lot of this PPE,”"

Ag workers aren't toddlers. They can don and doff. They can't fit test without access to fit testing equipment but that's not on them, that's on the agricultural industry to provide.

"Scientists have been concerned that H5N1 might spread to pigs, which are considered “mixing bowl” species for flu viruses because they carry the same kind of receptors on cells in their lungs as humans and birds."

H5N1 bird flu has been identified in a pig in the United States for the first time, the US Department of Agriculture said Wednesday.
