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.

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.

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.

This country profile presents a summary and analysis of Argentina's status with yellow fever. It is part of a series of profiles on this topic, each focusing on a different country in the Region of the Americas. Argentina's geographical location presents a wide territorial extension throughout diffe...rent latitudes, which determines a wide climatic variety, maintaining the conditions for the enzootic transmission of the yellow fever virus in jungle areas of the northeast of the country bordering Brazil and Paraguay. After controlling the major urban epidemics that hit the port city of Buenos Aires in the 20th century, Argentina maintains foci of enzootic activity in the northeast and isolated human cases for jungle acquisition. The increases in viral activity usually occur in a regional context of epizootics that affect southern Brazil and eastern Paraguay. Argentina has not presented autochthonous cases since 2008. Outbreaks have been sporadic with long intervals without evidence of viral activity.

Timely detection of novel coronavirus (2019-nCoV) infection cases is crucial to interrupt the spread of this virus. We assessed the required expertise and capacity for molecular detection of 2019-nCoV in specialised laboratories in 30 European Union/European Economic Area (EU/EEA) countries. Thirty-...eight laboratories in 24 EU/EEA countries had diagnostic tests available by 29 January 2020. A coverage of all EU/EEA countries was expected by mid-February. Availability of primers/probes, positive controls and personnel were main implementation barriers.

Ce rapport attire l’attention des intervenants sur le fait que la langue est importante pour établir la confiance avec les personnes touchées par le virus Ebola et d’autres épidémies et pour une communication efficace avec ces dernières.
The 2014–2015 Ebola epidemic in western Africa was the longest and most deadly Ebola epidemic in history, resulting in 28,616 cases and 11,310 deaths in Guinea, Liberia, and Sierra Leone. The Ebola virus has been known since 1976, when two separate outbreaks were identified in the Democratic Repub...lic of Congo (then Zaire) and South Sudan (then Sudan). However, because all Ebola outbreaks prior to that in West Africa in 2014–2015 were relatively isolated and of short duration, little was known about how to best manage patients to improve survival, and there were no approved therapeutics or vaccines. When the World Heath Organization declared the 2014-2015 epidemic a public health emergency of international concern in August 2014, several teams began conducting formal clinical trials in the Ebola affected countries during the outbreak.

Recognizing the extent to which the COVID-19 outbreaks affects women and men differently is hugely important. Some preliminary data suggested that more men than women are dying, potentially due to sex-based immunological differences, higher rates of cardiovascular disease for men and lifestyle choic...es, such as smoking. However, the experiences and lessons learned from the Zika and Ebola outbreaks and the HIV pandemic demonstrate that robust gender analysis and informed, gender-integrated response are vital to strengthen the access and acceptability of the humanitarian services needed to meet the distinct needs of women and girls, as well as men and boy and LGBTI people.
