Bird flu at poultry farms, updates 2025/2026 An overview of recent highly pathogenic bird flu infections on Dutch poultry farms

sacrificades des d’octubre, fa feredat, veure www.wur.nl/en/news/bird...). I recordin que a la península ibèrica, més de 150 brots en aus silvestres, amb milions d’aus sacrificades en desenes d’explotacions avícoles, estem gairebé igual, això sí, sens gats morts per #H5N1, o més ben dit,....

Bird flu at poultry farms, updates 2025/2026 An overview of recent highly pathogenic bird flu infections on Dutch poultry farms

(a EEUU encara no s’ha detectat infecció en humans a partir de llet contaminada, però, ni que aquesta es consumeixi crua, és una activitat de risc). Una no-anècdota, aquesta, associada a la intensa circulació de #H5N1 a les aus silvestres dels Països Baixos (amb 1,5 milions d’aus ...

On hi ha un foc pot haver-ne més, així que els serveis veterinaris començaren a testar totes les vaques (mostres de sang) i a prendre mostres de llet i... no es detectà virus enlloc però... una de les llets (d’una vaca) mostrà anticossos específics vs #H5N1, i això no pot ser si s'exposà...

Un historia de detectius... en una granja de vaquí lleter a Friesland (Països Baixos), el dia abans de Nadal, fa un mes, s’informà de gats malalts. Un d’ells morí dos dies després no sense que se li prenguessin mostres i es pogués detectar presència del virus #H5N1. www.science.org/content/arti...

The study commissioned by the Catalan government rules out that the African swine fever outbreak originated at IRTA: "It's a strain that has never been found before." The sequencing carried out by the IRB, parallel to the official study, concludes that the Collserola variant does not match any known sample.

African swine fever virus sequences from the IRTA-CReSA facility do not match those isolated from the wild boars that died at the start of the outbreak in Cerdanyola. The #labaccident hypothesis is fading, while the contaminated food hypothesis remains. #ASFV #OneHealth en.ara.cat/society/init...

Detecten un cas de grip aviària a l'Urgell, el primer en una granja de Catalunya des del 2023 - 3CatInfo És un virus molt contagiós i obliga a sacrificar tots els exemplars de la granja i a establir restriccions per a les situades en un radi de 10 quilòmetres del positiu

#Avianflu #Outbreak in #poultryfarm in #Catalonia. #H5N1 enters laying hen farm and will force killing of more than 230,000 specimens, as standard procedure. When environmental infectivity pressure is high, standard #biosecurity measures may not be sufficient. #OneHealth www.3cat.cat/3catinfo/det...

WASHINGTON, D.C., December 19, 2025—On December 14, 2025, USDA’s Animal and Plant Health Inspection Service (APHIS) announced the first detection of highly pathogenic avian influenza (HPAI) in a dairy herd in Wisconsin. On December 17, the National Veterinary Services Laboratories (NVSL) completed whole genome sequencing and confirmed that the virus is H5N1 clade 2.3.4.4b genotype D1.1. Analysis indicates that this detection is a new spillover event from wildlife into dairy cattle, separate from previous events.

Key Points

Most detections in U.S. dairy herds have resulted from movements linked to the original spillover event that occurred in the Texas Panhandle in late 2023, involving the B3.13 strain.
In early 2025, through the National Milk Testing Strategy, USDA detected two spillover events in Nevada and Arizona dairy herds. Both were identified early, and no further herd infections occurred through animal movements. These events involved the D1.1 strain.
The Wisconsin herd, also detected through the National Milk Testing Strategy, represents a new, separate spillover event and involves the D1.1 strain. At this time, no additional dairy herds have been identified as infected in association with this event.

#H5N1 : An infected herd was recently detected in Wisconsin, and genome sequencing indicates that this is yet another spillover event, making it the fourth detected one.

How do these spillovers happen and why are they restricted, so far, to the US?

El brot de #Marburg, un patogen #GP4, a #Etiopia continua creixent. 46 casos possibles amb 8 de confirmats i 4 morts. No hi ha cap vaccí comercial però sí alguns d'experimentals. Queda per veure si sera aprovat el seu ús d'emergència i arribaran a temps. #filovirus #OneHealth

Però no #H5N1 sinó #H5N5 la quel cosa ho converteix en una raresa i un recordatori que, al nostre voltant, els fenomens de recombinació són possibles, i si la circulació vírica és intensa i l'estació de l'any favorable, fins i tot són probables. #gripaviaria #transmissió

Last Ebola patient in Democratic Republic of the Congo discharged The last Ebola patient in the Democratic Republic of the Congo was discharged today, marking an important milestone in the efforts to end the outbreak.

The last patient with Ebola in the Democratic Republic of the Congo (#DRC) has recovered and been discharged. This marks a major step forward and begins a 42-day countdown to declaring the outbreak over.

Good news! Ring vaccinations against #Ebola have begun in DRC, according to @who.int:
“An initial 400 doses of the Ervebo Ebola vaccine—from the country’s stockpile of 2000 doses prepositioned in the capital Kinshasa—have been delivered to Bulape, one of the current hotspots of the outbreak.”

The #mpox Emergency Committee met yesterday and advised me that in its view, the situation no longer represents an international health emergency. I have accepted that advice.

Lifting the emergency declaration does not mean the threat is over, nor that our response will stop.
