title: Dengue virus infection in Croatia: seroprevalence and entomological study.
abstract: During 2011-2012, a total of 1,180 sera samples were collected from residents of seven Croatian counties located on the Adriatic Coast and four counties in northeastern Croatia and tested for the presence of dengue virus (DENV) IgG antibodies using ELISA. Reactive samples were further tested by IFA. Seven samples (0.59%) tested positive for DENV antibodies. Seroprevalence rates by county varied from 0-2.21%. The highest seropositivity rate (2.21%) was found in the Dubrovnik-Neretva County where autochthonous dengue cases were recorded in 2010. Additionally,3,699 mosquitoes were collected from 126 localities along the Adriatic coast in August-September, 2011. Aedes albopictus was the most prevalent species (81.37%). No evidence of DENV RNA was detected by RT-PCR among 1,748 female mosquitoes.
