SLEV genotype distribution from study of circulation of genotype II and III SLEV, by year and county, Texas, USA, 2009–2024. A) Dot plot of number of sequenced SLEV-positive mosquito pools for each year, by genotype and county. Each shape represents an individual mosquito pool. B) Map of Texas indicating presence of SLEV genotype II or III. Each genotype exclusively found in its respective counties; no counties had presence of both genotypes. SLEV, St. Louis encephalitis virus.
