Implication

Surveillance study reveals Usutu virus African 3.2 lineage infection in wild birds, suggesting a recent pathogen incursion from mainland Europe.

Key Points

Detect and characterize emerging Usutu virus infections among wild bird populations through national disease surveillance.
Screened wild birds in Greater London in August 2020 as part of a long-term wildlife disease surveillance programme.
Confirmed viral infection using reverse transcription-PCR, virus isolation, and immunohistochemical detection of flavivirus antigens in tissues.
Performed phylogenetic analysis to characterize the viral lineage and identify potential geographic origins.
Identified Usutu virus infection in five Eurasian blackbirds (Turdus merula) and one house sparrow (Passer domesticus).
Classified the isolates into the Usutu virus African 3.2 lineage, matching strains prevalent in Belgium and the Netherlands.
