Genetic diversity of toscana virus

Abstract

Distribution of Toscana virus (TOSV) is evolving with climate change, and pathogenicity may be higher in non-exposed populations outside areas of current prevalence (Mediterranean Basin). To characterize genetic diversity of TOSV, we determined the coding sequences of isolates from Spain and France. TOSV is more diverse than other well-studied phleboviruses (e.g.,Rift Valley fever virus).
