Genetic Characterization of the First Case of Lumpy Skin Disease in Singapore, 2022

Résumé fourni par la source

Lumpy Skin Disease (LSD) is a transboundary viral disease of wild and domesticated ruminants, and notifiable to the World Organisation for Animal Health (WOAH). LSD has spread rapidly in the cattle population across the African, European and Asian continents since 1929. Following recent outbreaks in the Southeast Asia region, Singapore observed its first occurrence of LSD in a local dairy cattle farm in March 2022. LSD was confirmed in dairy cattle exhibiting clinical signs with quantitative real-time PCR and sequencing with MinION Nanopore. Analyses of the assembled whole viral genomes also revealed high phylogenetic relatedness to LSD recombinant strains. It remains unclear how the virus was introduced into Singapore, given the absence of known vectors and strict import regulations in place. This highlights the importance of biosurveillance, and laboratory diagnostic readiness to manage outbreaks and prevent the spread of transboundary diseases.
