Highly pathogenic avian influenza outbreaks on fur farms in Spain and Finland underscore the vulnerability of these high-density confinement, open-air husbandry systems for the spread of infectious diseases. FVE, FECAVA and WSAVA support a phase-out of fur farming. fve.org/publications...
FVE, FECAVA and WSAVA position statement: Support for a phase-out of fur farming – FVE – Federation of Veterinarians of Europe
On 14 November 2025, the FVE General Assembly adopted the FVE, FECAVA and WSAVA position statement: Support for a phase-out of fur farming. FVE, the Federation of Companion Animal Veterinary Associations (FECAVA) and the World Small Animal Veterinary Association (WSAVA) call for the phasing out of fur farming globally. As veterinarians committed to animal health and welfare, public health and the protection of the environment, FVE, FECAVA and WSAVA believe that fur farming is no longer sustainable. Fur farming raises serious concerns regarding animal welfare and can have strong implications on public and environmental health. Therefore, when viewed through the One Health-One Welfare lens, it is disproportionate and unjustifiable.

Interestingly, the 1918, 1957 and 1968 pandemic viruses all had an avian-origin PB1 that enabled efficient replication at febrile temperatures.
I think this is one reason these pandemics caused so much severe disease.

How does fever work?
Our new Science paper shows how elevated body temperature can protect against severe influenza and that avian-origin viruses escape this defence.
This is likely one reason why bird flus and some pandemic influenzas can be so severe.🧵

“If there’s ever a year to get a flu vaccine, this is the year.”
Even in years with vaccine mismatches, the flu vaccine consistently prevents severe disease and hospitalizations. Now is the time to get a flu shot if you haven't already, because we will likely have a lot of flu activity this year.

Mutations in #H3N2 #flu viruses have some experts worried we're facing a second bad #influenza season. The new variant, subclade K, may be able to escape antibodies generated by previous infections or this year's flu shot. But some experts are hedging their bets. www.statnews.com/2025/11/20/f...
