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...

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.

#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? www.aphis.usda.gov/news/agency-...
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.
