Emergence of genotype III St. Louis encephalitis virus in the western United States potentially linked to a wetland in Argentina

In this study, genotype III SLEV was detected in mosquitoes collected in Mar Chiquita Lagoon (Córdoba, Argentina), an overwintering site for numerous migratory bird species. The genotype III SLEV sequence detected in this site shares the closest known ancestor with those introduced in Arizona in 2015. Our results highlight the potential significance of wetlands as key sites for arbovirus maintenance and emergence.PMID:38043673 | DOI:10.1016/j.actatropica.2023.107088
