[DURABLE @DURABLE_EU]

@DURABLE_EU researchers contributed to the first detection of West Nile virus in Belgium through advanced wildlife monitoring. This is crucial knowledge for protecting people and animals ahead of the 2026 mosquito season.

[BEACON @beacon_bio]

The 2025 West Nile virus season in Europe recorded 1112 human cases across 14 countries with 97 fatalities, representing the fourth highest annual total since surveillance began in 2008 and a 47% increase over the 10-year average

We're in full swing at EEID 2025! Come check out our poster or better even, both posters, to chat West Nile and Usutu virus! #EEID2025 @QuirineTB @OneHealthPact

[APHA @APHAgovuk]

APHA scientists have identified evidence of #WestNileVirus in UK #mosquitoes for the first time.

This important surveillance was carried out with partners as part of the @vb_radar project.

🔔This shows that the effectiveness of potential interventions, focused on preventing introductions or reducing within-LTCF transmission, varied over the course of the outbreak. Adaptive intervention planning might be the way to go!

[Mariken de Wit @MarikendeWit]

🖥️How? We explored contributions to the FOI in LTCF residents from 1) residents themselves, 2) health care workers, and 3) the general population using a Bayesian GLM.

[Mariken de Wit @MarikendeWit]

Take-aways:
- Within-LTCF transmission was substantially reduced after vaccination roll-out in LTCFs.
- Contributions to infection risk in residents varied over the course of the outbreak.
