Abstract
Toscana virus (TOSV) is a neglected sandfly-borne pathogen in Mediterranean countries. Although discovered four decades ago, articles that describe the clinical aspects are scarce and consist mostly of case reports, with few series of cases. We studied retrospectively symptomatic TOSV infections in patients hospitalized in Marseille (France) from 2004 to 2011. Seventeen patients were classified as probable or confirmed cases. Fourteen cases (82%) occurred between June and September, and 3 cases in March, April and November. Two cases were potentially imported from Croatia and Tuscany. All patients presented with fever and neurological signs were observed such as aseptic meningitis (n=6), muscular symptoms (n=3), or encephalitis (n=4). The outcome was always favorable. At the acute stage, anti TOSV IgM were observed in 14/17 patients, neutralization tests were positive for 3/8 patients, and RT-PCR confirmed TOSV infections in 5/8 CSF specimens.
