Dengue is one of the common arboviral infections and is a public health problem in South East Asia. The aim of this systematic review and meta-analysis was to evaluate the prevalence and distribution of dengue in SAARC (South Asian Associ...ation for Regional Cooperation) countries.

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 study shows the importance of an integrated entomological and medical surveillance for the evaluation of arboviral disease risk, which is a precondition for designing cost-effective vector control programs.
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.

Diferencias y similitudes del dengue y el COVID-19
During the COVID-19 pandemic, healthcare providers in areas where dengue is endemic or who are treating patients with recent travel history to these areas, need to consider dengue and COVID-19 in the differential diagnosis of acute febrile illnesses.

Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Symptoms typically beg...in three to fourteen days after infection. This may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash.Recovery generally takes two to seven days. In a small proportion of cases, the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs.
Dengue is spread by several species of mosquito of the Aedes type, principally A. aegypti.The virus has five different types;infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others. Subsequent infection with a different type increases the risk of severe complications. A number of tests are available to confirm the diagnosis including detecting antibodies to the virus or its RNA.
