  6. North Carolina has had 9 cases of West Nile virus so far this year. 3 cases were in Durham. Mosquitoes carry it; Durham did targeted mosquito spraying within ~1 mile of Trinity Park. Ok, good.

    I wonder how TP wound up w/ 3 diagnosed cases? My understanding is that ~1% or less of cases are diagnosed. I wonder if, maybe for economic reasons, folks in TP were simply more likely to be diagnosed? dconc.gov/DurhamCo-News/Public #DurhamNC #WestNile #arbovirus #publicHealth

    Abstract

    Background: Usutu virus (Orthoflavivirus usutuense, USUV), a neurotropic arthropod-borne RNA virus of the family Flaviviridae, is a zoonotic virus that has spread throughout the European continent over the last three decades, since its emergence in Italy in 1996. However, no cases of USUV have been reported in Portugal so far.

    Material and methods: In the scope of an active surveillance program for Orthoflavivirus, we collected growing feather samples from 249 red-legged partridges (Alectoris rufa) hunted in southern Portugal during the 2021-2023 hunting seasons. Samples positive for USUV were subjected to whole genome sequencing and strain characterization.

    Results: Two partridges tested positive for USUV. Phylogenetic analyses of whole and partial genomes assigned the USUV strains to the African 3 lineage, specifically the African 3.1 sub-lineage.

    Conclusions: Our study confirms, for the first time, the circulation of USUV in wild birds in Portugal. Active surveillance of hunted partridges proved to be a useful, accessible, and cost-effective method for USUV monitoring, further supporting their value as effective sentinels for Orthoflavivirus surveillance. Given the ongoing circulation of USUV and the increasing risk of its spillover to other domestic and wild animals, and humans, additional efforts are needed to improve virus surveillance in Portugal from a One Health perspective.
