          Abstract

          RESUMEN El dengue, chikungunya y zika son enfermedades del grupo de las arbovirosis, transmitidas por los mosquitos Aedes aegypti y Aedes albopictus. Estas enfermedades se han incrementado tanto en incidencia como en distribución geográfica, en una situación epidemiológica sumamente compleja, determinada por la variabilidad de las condiciones ambientales y por aspectos demográficos y socioeconómicos que favorecen su presencia. Por todo lo anterior es crucial mejorar el diagnóstico diferenciado de dichas enfermedades. El diseño de estrategias interprogramáticas y acciones intersectoriales como: educación, trabajo en la vivienda, tratamiento del agua, saneamiento básico, acciones medioambientales, desarrollo de agricultura y ganadería; todos necesarios para modificar los determinantes sociales y ambientales de estas enfermedades.

          ABSTRACT Dengue, chikungunya and zika are diseases belonging to the arbovirus group, transmitted by Aedes aegypti and Aedes albopictus mosquitoes. These diseases have increased both their incidence and geographical distribution, in a very complex epidemiologic situation, owing to the variability of the environmental conditions and demographical and socioeconomic aspects favoring their presence. Due to all before said it is crucial to improve the differentiated diagnosis of those diseases; designing new inter-program strategies and inter-sector actions like education, working in dwellings, water treatment, basic sanitary work, environmental actions, developing agriculture and cattle raising are all necessary to modify environmental and social determinant of these diseases.

          First report of autochthonous transmission of Zika virus in Brazil

          In the early 2015, several cases of patients presenting symptoms of mild fever, rash, conjunctivitis and arthralgia were reported in the northeastern Brazil. Although all patients lived in a dengue endemic area, molecular and serological diagnosis for dengue resulted negative. Chikungunya virus infection was also discarded. Subsequently, Zika virus (ZIKV) was detected by reverse transcription-polymerase chain reaction from the sera of eight patients and the result was confirmed by DNA sequencing. Phylogenetic analysis suggests that the ZIKV identified belongs to the Asian clade. This is the first report of ZIKV infection in Brazil.

              Suppression of a Field Population of Aedes aegypti in Brazil by Sustained Release of Transgenic Male Mosquitoes

              The increasing burden of dengue, and the relative failure of traditional vector control programs highlight the need to develop new control methods. SIT using self-limiting genetic technology is one such promising method. A self-limiting strain of Aedes aegypti, OX513A, has already reached the stage of field evaluation. Sustained releases of OX513A Ae. aegypti males led to 80% suppression of a target wild Ae. aegypti population in the Cayman Islands in 2010. Here we describe sustained series of field releases of OX513A Ae. aegypti males in a suburb of Juazeiro, Bahia, Brazil. This study spanned over a year and reduced the local Ae. aegypti population by 95% (95% CI: 92.2%-97.5%) based on adult trap data and 81% (95% CI: 74.9-85.2%) based on ovitrap indices compared to the adjacent no-release control area. The mating competitiveness of the released males (0.031; 95% CI: 0.025-0.036) was similar to that estimated in the Cayman trials (0.059; 95% CI: 0.011 – 0.210), indicating that environmental and target-strain differences had little impact on the mating success of the OX513A males. We conclude that sustained release of OX513A males may be an effective and widely useful method for suppression of the key dengue vector Ae. aegypti. The observed level of suppression would likely be sufficient to prevent dengue epidemics in the locality tested and other areas with similar or lower transmission.
