Integrated One Health Approach Tracks Arboviruses in Southern France: Insights from Yannick Simonin - LWNVIVAT Last Wednesday 19th of March LWNVIVAT project held the first seminar in our series on emergent pathogens, with a special focus on flaviviruses.

🖥️ In our recent webinar, Dr. Yannick Simonin described how his team tracks WNV and Usutu virus in southern France using a “One Health” approach that links human, animal, and environmental health.

Plea to 'take action' in gardens if blackbirds are spotted The Usutu virus, which is transmitted by the Culex pipiens mosquito - commonly known as the house mosquito - does not harm humans in the UK, but often proves fatal to birds

Help protect Blackbirds in our gardens from #UsutuVirus which is gaining ground in the UK

Figure 7 in Agliani et al. (2025): "Eight Eurasian blackbirds were sampled on day -7 (blood, serum, pharynx and cloacal swabs and breast feathers); after sampling, the blackbirds were singularly housed in cages in isolators and left to acclimatize for 7 days and activity and health status were monitored. On day 0, blackbirds were either inoculated with USUV Afr3 (n = 3), Eu3 (n = 3), or sterile PBS (n = 2). On 1, 3 and 5 days post inoculation (d.p.i.) blackbirds were sampled (blood, serum, pharynx and cloacal swabs and breast feathers). At the humane endpoint, blackbirds were euthanized, necropsied, and tissue samples were collected for histopathology, tissue titration and RT-qPCR. Created in BioRender, agreement licence number OO28BUTARJ."

Usutu-Virus befällt Amseln: Fast 90 Prozent der Amseln in Borken tot Seit Monaten breitet sich das Usutu-Virus auf Amseln im Kreis Borken aus. Die Lage sei so schlimm wie noch nie.

Klimawandel treibt Ausbreitung voran

Das Usutu-Virus, das ursprünglich in tropischen Regionen beheimatet ist, breitet sich seit über zwanzig Jahren in Europa aus. Es wird durch heimische Stechmücken übertragen, die das Virus von Vogel zu Vogel weitertragen.
