Phlebotomus-transmitted toscana virus infections of the central nervous system: a seven-year experience in Tuscany.

Toscana virus (TOSv) is a recently discovered Phlebotomus-transmitted human pathogen involved in acute infections of the central nervous system (CNS) occurring during the summer in natural foci in Italy. The purpose of this prospective study was to investigate the role of this virus in 170 patients with meningitis-meningoencephalitis of suspected viral origin, admitted to the Departments of Infectious Diseases at the Siena Hospital from 1990 to 1996. Infections caused by tick-borne encephalitis virus (TBEv) and TOSv or other neurotropic viruses were routinely diagnosed by means of conventional virological methods. 89 cases were attributed to TOSv, about 10% of which were Europeans on vacation in Tuscany. All of the TOSv-positive cases were observed during the summer and were residents of hilly areas in Siena and its province at an altitude not above 500 m. An increase in the number of cases was observed over the years, with a higher incidence among younger people. The clinical picture was similar to that observed in other viral infections of the CNS. Evolution was benign in all cases; in 2 subjects symptoms and signs of encephalitis were present.
