Cross-sectional survey for Toxoplasma gondii infection in humans in Fernando de Noronha island, Brazil

A cross-sectional survey reveals a significant seroprevalence of Toxoplasma gondii infection (50.4%) among residents of Fernando de Noronha Island, Brazil, marking the first epidemiological study of this zoonotic disease in the archipelago. Key risk factors identified include consumption of well or rainwater and game meat, with odds ratios of 2.43 and 1.80, respectively. The findings highlight the need for targeted prevention and control measures, particularly in island environments where water sources and dietary habits may pose higher infection risks.
