Immunoglobulin M seropositivity for Toscana virus in a random population sample in Sicily.
2012
Summary Objectives High Toscana virus (TOSV) antibody seropositivity rates have been documented in the last decade, especially in the Mediterranean area. It is unclear if these rates are associated with a recent or past exposure to the virus. This is of importance, as primary infection can cause neurologic complications, especially in adults. The aim of the present study was to assess the current active TOSV circulation in western Sicily. Methods A cross-sectional seroprevalence study was conducted on 271 individuals aged 4–92 years, sampled from the general population of a small city. Each participant completed a self-administered questionnaire and provided serum, which was analyzed for th…
Prevalence of Toscana sand fly virus antibodies in neurological patients and control subjects in Sicily
2012
Toscana sandfly fever virus (TOSV) is an arthropod-borne virus transmitted to humans by sandfly vectors. It has been associated with human cases of meningitis and meningo-encephalitis mainly occurring during the warm season. We performed a retrospective serological study to evaluate TOSV circulation in Palermo, Sicily, and to compare TOSV seroprevalence in patients with neurological symptoms and in a control group of patients without neurological symptoms. When sera from 155 patients with and without neurological symptoms were evaluated, the rate of overall TOSV IgG reactivity was 17.4%. Patients with neurological symptoms showed a higher percentage of TOSV IgG positivity than control patie…
Seroprevalence of and risk factors for Toscana and Sicilian virus infection in a sample population of Sicily (Italy).
2011
Summary Objective The present study aimed to assess seroprevalence of and risk factors for Toscana (TOSV) and Sicilian (SFSV) virus infections in a sample of Sicilian subjects. Methods A cross-sectional seroepidemiological study was conducted on 271 individuals. Each participant completed a self-administrated questionnaire and provided a serum sample which was analyzed for the presence of IgG specific anti-TOSV and anti-SFSV viruses. Results Overall, 90 subjects (33.2%) were positive for TOSV IgG, 25 (9.2%) were positive for SFSV IgG and 11 (4%) were positive for both the viruses. A higher risk for TOSV seropositivity was found in participants who were older (adjOR = 1.02 per year; 95% CI =…
