Para la población de la isla, el hallazgo indica que el contacto con mosquitos es real y no está distribuido de forma pareja. Para un argentino, sirve como recordatorio de que las enfermedades transmitidas por insectos se mueven con el clima y con las personas. El estudio muestra exposición pasada, no cuántos enfermos hay hoy, y esa diferencia pesa mucho.","quienFirma":"Investigación sobre Ifanadiana, Madagascar (región rural)","confianza":"preprint","consulta":null},"sello":{"hash":"032098382f0ae5ba78dc04a83a1b4a545d9b69ccd199f2f25c9826e58daf9326","sello":"fe7be91e2d3dc9bbc467913f355dc889593845630bec00e6f9fb5481798c03ff","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6575877,"aleatorio":"8f37ac72f463d512f17e7eb8a85fbb051e22a02b20832cc61f9e99cd899bcc20","tiempo":"2026-10-22T22:15:30.000Z"},"nist":{"cadena":2,"pulso":1995138,"salida":"18500D4D946F3E5BEBC75649FB9B2988974DA4AC1B8418F823282A208CE8DD90C1D97B1374796A643771A12D02A91E9E9CE7C7FA3DCC7A707FC3EE1B862BF5F9","tiempo":"2026-10-22T22:15:00.000Z"},"noAntes":"2026-10-22T22:15:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 22 22:15:54 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Spatial modeling of risk factors for human exposure to West Nile virus in rural Madagascar","descripcion":"Background West Nile virus (WNV) is an emerging disease transmitted from bird hosts to humans by Culex mosquitoes. Thousands of human cases of WNV infection are reported each year in the United States and Europe, and circulation has been confirmed in Africa and the Indian Ocean, including Madagascar. However, little is known about the current riskscape for people in Madagascar, and what determines its local distribution and human exposure across the population. The goal of this study was to assess WNV seroprevalence and identify associated socio-ecological risk factors in rural Madagascar.
