En la actualidad, las guías basadas en la evidencia constituyen una de las herramientas más útiles para mejorar la salud pública y la práctica clínica. Su finalidad es formular intervenciones con sólidas pruebas de eficacia, evitar riesgos innecesarios, utilizar los recursos de forma eficient...e, disminuir la variabilidad clínica y, en esencia, mejorar la salud y garantizar una atención de calidad, razón de ser de los sistemas y servicios de salud. Las presentes directrices se elaboraron siguiendo la metodología GRADE con el apoyo de un panel de expertos clínicos de distintos países, todos ellos convocados por la Organización Panamericana de la Salud. Por medio de la respuesta a doce preguntas clave sobre el diagnóstico clínico y el tratamiento del dengue, el chikunguña y el zika, se formulan recomendaciones basadas en evidencia para pacientes pediátricos, jóvenes, adultos, personas mayores y embarazadas expuestos a estas enfermedades o con sospecha o diagnóstico confirmado de infección. La finalidad de las directrices es evitar la progresión a las formas graves y a los eventos mortales que puedan causar. Las recomendaciones están dirigidas a profesionales de la salud, incluidos el personal médico general, residente y especialista; y los profesionales de enfermería, así como a estudiantes de medicina y enfermería, quienes de una u otra forma participan en la atención de pacientes con sospecha de dengue, chikunguña o zika. También se dirige a los administradores de las unidades de salud y a los equipos directivos de los programas nacionales de prevención y control de enfermedades arbovirales, quienes tienen la responsabilidad de facilitar el proceso de aplicación de estas directrices. Esperamos que esta publicación beneficie no solo al personal de salud, que dispondrá de información científica actualizada y de la mejor calidad posible, sino a los menores, los adultos, las embarazadas, las personas mayores y la población en general, quienes recibirán una mejor atención de salud prestada por personal médico debidamente capacitado.

Evidence-based guidelines are one of the most useful tools for improving public health and clinical practice. Their purpose is to formulate interventions based on strong evidence of efficacy, avoid unnecessary risks, use resources efficiently, reduce clinical variability and, in essence, improve hea...lth and ensure quality care, which is the purpose of health systems and services. These guidelines were developed following the GRADE methodology, with the support of a panel of clinical experts from different countries, all convened by the Pan American Health Organization. By responding to twelve key questions about the clinical diagnosis and treatment of dengue, chikungunya, and Zika, evidence-based recommendations were formulated for pediatric, youth, adult, older adult, and pregnant patients who are exposed to these diseases or have a suspected or confirmed diagnosis of infection. The purpose of the guidelines is to prevent progression to severe forms of these diseases and the fatal events they may cause. The recommendations are intended for health professionals, including general, resident, and specialist physicians, nursing professionals, and medical and nursing students, who participate in caring for patients with suspected dengue, chikungunya, or Zika. They are also intended for health unit managers and the executive teams of national arboviral disease prevention and control programs, who are responsible for facilitating the process of implementing these guidelines.

Dengue creates a staggering epidemiological and economic burden for endemic countries. Without a specific therapy and with a commercial vaccine that presents some problems relative to its full effectiveness, initiatives to improve vector... control strategies, early disease diagnostics and the development of vaccines and antiviral drugs are priorities. In this study, we present the probable origins of dengue in America and the trajectories of its spread. Overall, dengue diagnostics are costly, making the monitoring of dengue epidemiology more difficult and affecting physicians’ therapeutic decisions regarding dengue patients, especially in developing countries. This review also highlights some recent and important findings regarding dengue in Brazil and the Americas. We also summarize the existing DENV polymerase chain reaction (PCR) diagnostic tests to provide an improved reference since these tests are useful and accurate at discriminating DENV from other flaviviruses that co-circulate in the Americas. Additionally, these DENV PCR assays ensure virus serotyping, enabling epidemiologic monitoring.

The arrival and rapid spread of the mosquito-borne viral disease Chikungunya across the Americas is one of the most significant public health developments of recent years, preceding and mirroring the subsequent spread of Zika. Globalization in trade and travel can lead to the importation of these vi...ruses, but climatic conditions strongly affect the efficiency of transmission in local settings. In order to direct preparedness for future outbreaks, it is necessary to anticipate global regions that could become suitable for Chikungunya transmission. Here, we present global correlative niche models for autochthonous Chikungunya transmission. These models were used as the basis for projections under the representative concentration pathway (RCP) 4.5 and 8.5 climate change scenarios. In a further step, hazard maps, which account for population densities, were produced. The baseline models successfully delineate current areas of active Chikungunya transmission. Projections under the RCP 4.5 and 8.5 scenarios suggest the likelihood of expansion of transmission-suitable areas in many parts of the world, including China, sub-Saharan Africa, South America, the United States and continental Europe. The models presented here can be used to inform public health preparedness planning in a highly interconnected world.
