Dengue vaccine for 9 to 16 year old's with previous dengue infection.
Dengue Vaccines: Current Status and Future Prospects
In this document, recommendations are provided on designing and implementing
a cross-sectional serosurvey using school-based sampling to estimate age-specific
DENV seroprevalence to inform a country’s national dengue vaccination program.
The document includes recommendations for methods for ...planning and conducting
serosurveys, including survey design, specimen collection, laboratory testing, data
analysis, and the interpretation and reporting of results.

There are currently 4 different serotypes of Dengue virus known to science. Each time someone get infected and recovers, the individual will be protected by a lifelong immunity from further infection against that specific serotype and that serotype only.
Consequent infection from different serotype... not only will infect the individual but may also cause a more serious or severe disease progression.

Epidemiological Update
Dengue
7 February 2020
Situation summary
In the Region of the Americas, between epidemiological week (EW) 1 and EW 521 of 2019, a total of 3,139,335 cases of dengue have been reported (321.58 cases per 100,000 population), including 1,538 deaths. Of the total cases, 1,367,...353 (43.6%) were laboratory-confirmed and 28,169 (0.9%) were classified as severe dengue. The case-fatality rate was 0.049%.

The aim of this toolkit is to guide countries on how to best estimate their current burden of dengue by combining existing data from dengue surveillance systems with on-going research efforts to measure the community burden
of dengue.
Dengue is a significant public health problem. There are four dengue virus serotypes identified; however, its diagnosis is difficult due to the existence of many viruses, bacteria, and parasites producing the same clinical presentation, being present in the same geographical area and even producing ...coinfections. Therefore, determining whether a person has, had, or is infected with dengue virus is of great importance. In order to do so, direct and indirect laboratory tests have been developed to identify the virus or part of its structure that generally detects the antibody response. These techniques are used for diagnosis, epidemiological studies, monitoring, assessment and production of vaccines and antivirals, etc. They range from the use of cell cultures, animal models, inoculation by insects, and serology tests to the use of detection molecular tests and quantification of genetic material that are described in this chapter herein, a brief explanation of this methodology, its strengths and weaknesses, and its application in the dengue research.

Dengue is the fastest spreading, mosquito-borne viral infectious disease worldwide, with remarkable morbidity and mortality. In the past decades, profound contributions have been made towards understanding its epidemiology, including disease burden and distributions, risk factors, and control and pr...evention practices. Dengue continues to disseminate to new areas, including high latitude regions, and a new serotype (dengue virus serotype 5) has been identified. Vaccine research has made new progress, in which the licensed yellow fever and dengue virus quadrivalent chimeric vaccine is now under further safety assessment. In disease surveillance, because of its operational simplicity, rapidity, capability, and utility as an indicator of disease severity, dengue virus NS1 antigen detection has great promotion and application value among primary health care institutions. Vector control progress has driven new breakthroughs in biotechnology, including Wolbachia-infected Aedes and genetically modified Aedes. Both Aedes variants have been used to block transmission of the dengue virus through population replacement and suppression. In the future, vector control should still be pursued as a key measure to prevent transmission, along with anti-viral drug and vaccine research.

PROGRAM DESCRIPTION: Course is designed to increase knowledge and develop competency in the management of patients suspected of infection with dengue virus.
El propósito de este curso es proveer al personal de salud encargado de atender casos sospechosos de dengue la información necesaria para realizar un diagnóstico y manejo clínico oportuno, evitando la progresión a las formas graves y las muertes ocasionadas por esta enfermedad.
This first online course is geared at helping healthcare workers in diagnosing and managing all aspects of dengue in order to avoid complications and fatalities.
This course was developed with a comprehensive vision. It is divided into seven modules that include:
Epidemiological informatio...n on dengue,
Pathophysiology of clinical manifestations,
Clinical and differential diagnosis,
Severity classification,
Recommendations for the management of dengue according to its severity and
Managing patients with comorbidities.

Dengue is a mosquito-borne viral disease that has rapidly spread to all regions of WHO in recent years. Dengue virus is transmitted by female mosquitoes mainly of the species Aedes aegypti and, to a lesser extent, Ae. albopictus. These mosquitoes are also vectors of chikungunya, yellow fever and Zik...a viruses. Dengue is widespread throughout the tropics, with local variations in risk influenced by climate parameters as well as social and environmental factors.

El dengue es una enfermedad vírica transmitida por mosquitos que en los últimos años se ha propagado rápidamente a todas las regiones de la OMS. El virus del dengue se transmite a través de mosquitos hembra principalmente de la especie Aedes aegypti y, en menor grado, de la especie Ae. albopict...us. Estos mosquitos también son vectores de los virus de la fiebre chikungunya, la fiebre amarilla y el Zika. La enfermedad está muy extendida en los trópicos, con variaciones locales en el riesgo que dependen de los parámetros climáticos y de los factores sociales y ambientales.

La dengue est une maladie virale transmise par les moustiques qui s’est rapidement propagée dans toutes les Régions de l’OMS ces dernières années. Le virus de la dengue est transmis par des moustiques femelles, principalement de l’espèce Aedes aegypti, mais aussi dans une moindre mesure A...e. albopictus. Ces moustiques sont aussi vecteurs du virus du chikungunya, du virus amaril et du virus Zika. La dengue est largement répandue sous les tropiques, avec des variations locales du risque qui dépendent des caractéristiques climatiques, ainsi que de facteurs sociaux et environnementaux.

Dengue Epidemiology
The first record of a case of probable dengue fever is in a Chinese medical encyclopedia from the Jin Dynasty (265–420 AD) which referred to a “water poison” associated with flying insects. The first recognized Dengue epidemics occurred almost simultaneously in Asia, Afr...ica, and North America in the 1780s, shortly after the identification and naming of the disease in 1779. The first confirmed case report dates from 1789 and is by Benjamin Rush, who coined the term "breakbone fever" because of the symptoms of myalgia and arthralgia.
