Phlebotomine sand fly-borne pathogens such as spp. and phleboviruses are emerging threats to humans and animals worldwide. The aim of this work was to evaluate the exposure of cats from Portugal to Toscana virus (TOSV) and Sandfly Fever Sicilian virus (SFSV) and assess the associated risk factors. The possible association between exposure to saliva with TOSV and SFSV was also investigated. Out of 369 cats tested, 18 (4.9%, = 365) were seropositive for TOSV, and eight (2.2%, = 367) were seropositive for SFSV. Multivariate logistic regression analysis showed that cats presenting clinical signs that were compatible with leishmaniosis and antibodies to TOSV had a significantly higher risk of being SFSV seropositive. The presence of antibodies to sand fly-borne viruses in cats indicate that these animals are frequently exposed to sand flies and transmitted pathogens. Data suggest that cats can be used to qualitatively monitor human exposure to TOSV and SFSV in endemic areas. The clinical impact of SFSV in cats' health should be investigated. The identification of the sand fly species responsible for the circulation of TOSV and SFSV in nature and the evaluation of the vectorial competence of to SFSV should also be addressed.

Article Synopsis
  • Eight phleboviruses transmitted by sandflies have been identified in North Africa, with an infection rate of 0.02-0.6% among the virus-carrying sandfly species.
  • Seroprevalence studies show low rates of Toscana virus (TOSV) in dogs from Algeria and Tunisia, while Sandfly Fever Sicilian virus (SFSV) and Punique virus (PUNV) have higher rates in Tunisia.
  • Among humans, TOSV and SFSV are the most prevalent, with TOSV confirmed in Algeria and Tunisia, while other phleboviruses have been detected to a lesser extent, indicating a need for further research into their epidemiology.

The aim of this study was to determine the prevalence of six viruses, from two families of the order , in the general population of central Tunisia. Sera collected from 377 asymptomatic blood donors were serologically assayed for Rift Valley fever virus (RVFV), Crimean-Congo hemorrhagic fever virus (CCHFV), and four sandfly-borne phleboviruses: Toscana virus (TOSV), sandfly fever Naples virus (SFNV), sandfly fever Sicilian virus (SFSV), and sandfly fever Cyprus virus (SFCV). Of the 377 subjects enrolled in this study, 17.

Sandfly-borne phleboviruses are endemic in countries around the Mediterranean Basin and pose a significant health threat for populations, with symptoms spanning from febrile diseases to central nervous system involvement. We carried out a comprehensive cross-sectional screening via microneutralization (MN) assays for a quantitative assessment of neutralizing antibodies (NAs) to seven phleboviruses representing three distinct serocomplexes, using samples previously screened via immunofluorescence assays (IFAs) in Turkey, an endemic region with various phleboviruses in circulation. We detected NAs to three phleboviruses: Toscana virus (TOSV), sandfly fever Naples virus (SFNV), and sandfly fever Sicilian virus (SFSV), while assays utilizing Adana virus, Punique virus, Massilia virus, and Zerdali virus remained negative.

High seroprevalence rates of several phleboviruses have been reported in domestic animals and humans in sandfly-infested regions. Sandfly Fever Sicilian virus (SFSV) and Toscana virus (TOSV) are two of these viruses commonly transmitted by sandflies. While SFSV can cause rapidly resolving mild febrile illness, TOSV could involve the central nervous system (CNS), causing diseases ranging from aseptic meningitis to meningoencephalitis.

Article Synopsis
  • * A study in northern Spain analyzed the serum from Common Quail to determine the prevalence of antibodies against TOSV and SFSV, testing 106 and 110 samples respectively from different years.
  • * The results showed significant neutralizing antibody rates for both viruses (45.45% for SFSV and 42.45% for TOSV), suggesting that quails might play a role as amplifying hosts in the lifecycle of these phleboviruses.*
