Resumo: | A comprehensive cohort study including an entomological surveillance component can contribute to our knowledge of clinical aspects and transmission patterns of arbovirosis. This article describes the implementation of a populational-based birth cohort study that included an entomological surveillance component, and its associated challenges in a low-income community of Rio de Janeiro, Brazil. The participants were recruited in two periods: from 2012 to 2014, and from 2015 to 2017. The children had scheduled pediatric consultations and in case of fever. Epidemiological, clinical data and biological samples were collected at pediatric visits. Active febrile surveillance was performed by telephone calls, social networking, message apps, and household visits. A total of 387 newborns and 332 new children were included during the first and second recruitment periods, respectively. By July 2017, there were 451 children on follow-up. During the study, 2,759 pediatric visits were performed: 1,783 asymptomatic and 976 febrile/rash consultations. The number of febrile or rash consultations increased 3.5-fold after the use of media tools for surveillance. No temporal pattern, seasonality or peak of febrile cases was observed during the study period. A total of 10,105 adult mosquitoes (including 3,523 Aedes spp. and 6,582 Culex quinquefasciatus) and 46,047 Aedes eggs were collected from households, schools, and key sites. Although challenging, this structured sentinel populational-based birth cohort is relevant to the knowledge of risks and awareness of emerging pathogens. |

Este artículo describe la implementación de un estudio poblacional de cohorte de nascimientos que incluyó el componente de vigilancia entomológica y los desafios asociados en una comunidad desfavorecida de Río de Janeiro, Brasil. Los participantes fueron captados en dos periodos: de 2012 a 2014 y de 2015 a 2017. Los niños tenían fijadas consultas pediátrica regulares y por fiebre. Durante las visitas pediátricas, se recogieron datos epidemiológicos y clínicos, así como muestras biológicas. Se realizó una vigilancia activa de la fiebre mediante llamadas telefónicas, redes sociales, aplicaciones de mensajes, y visitas a domicilio. Un total de 387 recién nacidos y 332 nuevos niños fueron incluidos durante el primer y segundo período de reclutamiento, respectivamente. En julio de 2017 se había realizado un seguimiento a 451 niños. Durante el estudio, se realizaron 2.759 visitas pediátricas: 1.783 asintomáticas y 976 por fiebre/urgencias. El número de consultas por fiebre o urgencias aumentó 3.5-veces tras el uso de herramientas de comunicación para la viglancia. No se observaron patrones temporales, estacionalidad o casos de picos de fiebre durante el periodo de estudio. Un total of 10.105 mosquitos adultos (incluyendo 3.523 Aedes spp. y 6.582 Culex quinquefasciatus) y 46.047 huevos fueron recogidos de viviendas, escuelas, y lugares estratégicos. A pesar de los retos, esta cohorte de nacimiento estructurada y supervisada, basada en población es relevante para el conocimiento de los riesgos y la concienciación sobre patógenos emergentes.Estudos de coorte com um componente de vigilância epidemiológica podem contribuir para nosso conhecimento dos aspectos clínicos e dos padrões de transmissão de arboviroses.

Durante o estudo, foram realizadas 2.759 visitas pediátricas: 1.783 assintomáticas e 976 consultas por febre/exantema. O número de consultas por febre ou exantema aumentou 3,5 vezes após uso de ferramentas de mídia para vigilância. Nenhum padrão temporal, sazonalidade ou pico de casos de febre foi observado durante o período do estudo.
