Seroepidemiological survey for antibodies to arboviruses in Greece
Plaque reduction neutralization (PRN) and indirect immunofluorescence (IFA) tests were used to detect human antibodies to certain viruses of the families Flaviviridae and Bunyaviridae. Blood samples for the serosurveys were mainly collected from healthy farmers, wood cutters and shepherds. By PRN test antibodies were found to West Nile, sandfly fever Naples, and sandfly fever Sicilian viruses with seropositives 1.2%, 16.7%, and 2.0%, respectively. Antibodies to Rift Valley fever virus were not detected. By IFA tests, antibodies to the phlebovirus Corfu, tick-borne encephalitis, Crimean-Congo hemorrhagic fever, and Hantaan viruses were found with seropositives 4.0%, 1.7%, 1.0%, and 3.4%, respectively. Epidemiological data concerning the geographic and occupational distributions of the infected individuals are discussed.
