AI Article Synopsis

  • - The study aimed to determine how common Toscana virus (TOSV) and Sicilian virus (SFSV) infections are in a group of Sicilian individuals and to identify any associated risk factors. - Out of 271 participants, 33.2% tested positive for TOSV, 9.2% for SFSV, and 4% for both, with older age, having an outdoor pet, and obesity being linked to higher TOSV positivity. - Conclusions indicate a notable level of TOSV in the Sicilian population, particularly among older adults, while suggesting that TOSV and SFSV may differ in their ecology and transmission strategies, as risk factors were not shared between the two viruses.

Article Abstract

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 = 1.01-1.03), having a pet living outdoors (adjOR = 2.62; 95% CI = 1.42-4.83) and being obese (adjOR = 2.37; 95% CI = 1.06-5.30).

Conclusions: TOSV seroprevalence appears to be relatively high in Sicilian general population, especially in older adults, representing a potential public health concern. The observations that seropositivity for TOSV was not significantly associated with SFSV seropositivity, and none of the risk factors associated with TOSV were associated with SFSV seem to suggest that these two phleboviruses may have different ecology and transmission pathways.
