OBJECTIVE: To evaluate the results obtained by a surveillance network on arbovirosis composed by doctors and nurses located at hospitals and Primary Care trained in their identification, diagnostic confirmation and clinical management. LOCATION: North Metropolitan Area of Barcelona (1,400,000 inhabitants; Catalonia; Spain) during a calendar year. PARTICIPANTS: Seven Primary Care and 10 hospital physicians plus 4 Primary Care nurses. TYPE OF STUDY: A prospective observational study. MAIN MEASUREMENTS: Demographic, epidemiological (autochthonous/imported, suspect/probable/confirmed case) and healthcare variables (symptoms, serological profile, viral period) were defined. RESULTS: Of the 34 patients identified, 26 (76.5%) met study criteria. Among them, any arbovirosis was confirmed in 14 (53.8%): 13 dengue plus 1chikungunya fever. There were no cases of Zika fever. There was a history of travel to endemic areas 23 (88.4%), but not in 3cases (11.6%) in which the possibility of an indigenous transmission was considered; of them, a case of dengue was confirmed. The estimated incidence of arbovirosis was 0.4 (95%CI: 0.33-0.51) cases ×10,000hab/year which, when compared to the estimated incidence in the same geographical area during the period 2009-2013 (0.19cases ×10,000hab/year; 95%CI: 0.07-0.31), a significant increase was found (P=.044). Patients within viremia period at the time of their first medical visit were 11 (42.3%). CONCLUSIONS: An intensified epidemiological surveillance program defined at Primary Care and hospital levels is able to detect significantly more cases of imported and autochthonous arbovirosis. Possibly we are witnessing an increase in the incidence of imported arbovirosis and, thus, measures aimed at their identification and confirmation should be reinforced.

In August 2020, during the coronavirus disease (COVID-19) pandemic, five locally acquired cases of dengue virus type 1 were detected in a family cluster in Vicenza Province, North-East Italy where Aedes albopictus mosquitoes are endemic. The primary case was an importation from West Sumatra, Indonesia. This is the first outbreak of autochthonous dengue reported in Italy. During the COVID-19 pandemic, screening of febrile travelers from endemic countries is crucial in areas where competent vectors are present.

Vector borne viruses (VBV) include viruses transmitted by arthropods, rodents and other animals. In Spain the three main autochthonous VBVs causing human diseases are: Toscana, West Nile and Lymphocytic Choriomeningitis viruses. There are also other imported viruses that are potential threats to our public health, due to the presence of competent transmission vectors (dengue and chikungunya viruses in areas infested with Aedes albopictus), or due to the potential person-to-person transmission (Lassa and other viruses causing haemorrhagic fever). The Spanish Society for Infectious Diseases and Clinical Microbiology has responded to the emergence of VBVs by publishing a special issue of Microbiological Proceedings focused on the diagnosis of those emerging vector borne viruses of major concern in our country.

Arthropod-borne viral diseases are likely to be affected by the consequences of climate change with an increase in their distribution and intensity. Among these infectious diseases, chikungunya and dengue viruses are two (re)emergent arboviruses transmitted by Aedes species mosquitoes and which have recently demonstrated their capacity for rapid expansion. They most often cause mild diseases, but they can both be associated with complications and severe forms. In Europe, following the establishment of invasive Aedes spp, the first outbreaks of autochtonous dengue and chikungunya have already occurred. Northern Europe is currently relatively spared, but climatic projections show that the conditions are permissive for the establishment of Aedes albopictus (also known as the tiger mosquito) in the coming decades. It is therefore essential to question and improve the means of surveillance in northern Europe, at the dawn of inevitable future epidemics.
RESUMO
The definitive diagnosis of the Rift Valley fever virus (RVFV) requires a form of testing that is available only in reference laboratories. It includes indirect immunofluorescence assay (IFA), the serum neutralization assay (NA), and real-time PCR. Therefore, often, no attempts are made to detect it, even among travelers from endemic areas. In this study, the presence of anti-RVFV IgG and IgM was retrospectively screened in stored serum samples from people who were admitted with arbovirus symptoms at the National Institute for Infectious Diseases (INMI) L. Spallanzani, Rome, Italy. Overall, 80 residual serum samples were anonymized, and sub-aliquots were prepared and tested for anti-RVFV IgG and IgM. A serum neutralization assay was used as a confirmatory test. There was a positive result in eight out of 80 samples (10%) for anti-RVFV IgG, with titers ranging from 1:40 up to 1:1280. Three of eight (2.6%) samples were confirmed as seropositive through an in-house serum neutralization assay, with antibody titers ranging from 1:10 to 1:160. All samples resulted negative for anti-RVFV IgM and RVFV RNA when tested by IFA and real-time RT-PCR, respectively. Our data highlight that several RVFV infections can possibly escape routine virological diagnosis, which suggests RVFV testing should be set up in order to monitor virus prevalence.
RESUMO
OBJECTIVE: Environmental management of imported arboviruses such as dengue (DENV), Zika (ZIKV) or Chikungunya (CHIKV) is a task of great significance for Public Health since the arrival and establishment of the competent vector Aedes albopictus (Asian tiger mosquito) in numerous cities of our country. There are recent examples of autochthonous transmission of some of these arboviruses in Spain probably linked to undetected and / or unmanaged imported cases. METHODS: Vector management interventions were carried out in the city of Valencia (Spain) by the Health Service of the Valencia City Council between 2016 and 2018. These actions took place within the framework of a coordination protocol established with the Health authorities of the Valencia regional government. RESULTS: A total of 21 arbovirus cases were reported and led to entomological surveillance and vector control interventions in the city of Valencia: 8 DENV, 7 CHIKV and 6 ZIKV. In 8 of these 21 cases (38%) the presence of Ae. Albopictus was detected within the risk zones established for each case. CONCLUSIONS: Vector surveillance and control strategies associated with imported cases of arboviruses, provide accurate information on the environmental risks of amplification of these viruses and also allow reducing these risks through population control of vectors. Due to the short duration of the viremic phases, these interventions should be carried out as quickly as possible in order to reduce the hypothetical contact between the infected person and vector as much as possible.
OBJETIVO: La gestión ambiental de arbovirosis importadas como dengue (DENV), Zika (ZIKV) o Chikungunya (CHIKV) es una tarea de gran significancia para la Salud Pública desde la llegada y establecimiento del vector competente Aedes albopictus (mosquito tigre) a numerosas ciudades de nuestro país. Existen ejemplos recientes de transmisión autóctona de algunas de estas arbovirosis en España que, supuestamente, tienen su origen probablemente en casos importados no detectados y/o no gestionados. METODOS: Se llevaron a cabo intervenciones de manejo antivectorial en la ciudad de València por parte del Servicio de Sanidad del Ayuntamiento, entre los años 2016 y 2018. Dichas actuaciones se produjeron en el marco de un protocolo de coordinación establecido con la Conselleria de Sanitat de la Generalitat Valenciana. RESULTADOS: Un total de 21 casos de arbovirosis fueron comunicados y derivaron en intervenciones ambientales de vigilancia entomológica y control vectorial en la ciudad de València: 8 DENV, 7 CHIKV y 6 ZIKV. En 8 de estos 21 casos (38%) se identificó la presencia de Ae. albopictus dentro de las zonas de riesgo establecidas para cada caso. CONCLUSIONES: Estrategias de vigilancia y control vectorial asociadas a los casos importados de arbovirosis, aportan información precisa de los riesgos ambientales de amplificación de estas virosis y permiten también reducir dichos riesgos a través del control poblacional de los vectores. Debido al corto tiempo de duración de las fases de viremia, dichas intervenciones deben realizarse con la mayor celeridad posible en aras de poder reducir al máximo el hipotético contacto entre persona infectada y vector.

ABSTRACT Background: Zika virus is a newly emerging infection, associated with increasingly large outbreaks especially in tropical countries such as Brazil. A future Zika vaccine can contribute to decreasing the number of cases and associated complications. Information about consumers' willingness to pay (WTP) for a hypothetical Zika vaccine can help price setting discussions in the future in Brazil, starting with the private market. METHODS: A cross-sectional study conducted among residents of Minas Gerais, Brazil, regarding their WTP for a hypothetical Zika Vaccine. The mean effective protection was 80%, with the possibility of some local and systemic side- effects. RESULTS: 517 people were interviewed. However, 28 would not be vaccinated even if the vaccine was free. Most of the resultant interviewees (489) were female (58.2%), had completed high school (49.7%), were employed (71.2%), had private health insurance (52.7%), and did not have Zika (96.9%). The median individual maximum WTP for this hypothetical Zika vaccine (one dose) was US$31.34 (BRL100.00). CONCLUSION: Such discussions regarding WTP can contribute to decision-making about prices once a Zika vaccine becomes available in Brazil alongside other ongoing programs to control the virus.

INTRODUCCIÓN: La infección por hantavirus es endémica en América del Sur, con un amplio espectro de gravedad y una letalidad que varía entre 17 y 40 por ciento. El presente estudio recoge información de 25 años de vigilancia epidemiológica en Buenos Aires, Argentina. OBJETIVO: Caracterizar el comportamiento de la serie temporal 1997-2021, observando tendencia y estacionalidad. MÉTODOS: La función de serie temporal utilizada empleó la media móvil centrada según periodos trimestrales, de forma que cada año se dividió en cuartiles. Se consideró un modelo multiplicativo. RESULTADOS: Con una tasa de mortalidad de la serie de 0,15 por 100 mil y de letalidad de 22,6, la razón varones : mujeres fue de 3,4:1. La distribución sindrómica mostró mayor compromiso renal, siendo la tasa de mortalidad prácticamente igual en ambos sexos. CONCLUSIÓN: Como enfermedad infecciosa, la infección por hantavirus reflejó en los últimos 25 años un comportamiento, recurrente y estacional, endémico y compartido en sus características clínicas con el resto de la región andina.
BACKGROUND: Hantavirus infection is endemic in South America, with a wide spectrum of severity and a fatality rate that varies between 17-40 percent. This study collects information from 25 years of epidemiological surveillance in Buenos Aires, Argentina. AIM: To characterize the behavior of the 1997-2021 time series, observing trends and seasonality. METHODS: The time series function used the moving average centered according to quarterly periods, so that each year was divided into quartiles. A multiplicative model is missed. RESULTS: With a mortality rate for the series of 0.15 per 100,000 and a fatality rate of 22.6, the male : female ratio was 3.4:1. The syndromic distribution showed greater renal involvement, with the mortality rate being practically the same in both sexes. CONCLUSION: As an infectious disease, hantavirus has reflected in the last 25 years a behavior, recurrent and seasonal, endemic and shared in its clinical characteristics with the rest of the Andean region.

The recent outbreak of Zika virus infection in Brazil has aroused considerable media interest due to its association with neurological malformations in children born from mothers infected by the virus and to its association with Guillain-Barre syndrome in adults. This relationship has led to the World Health Organisation declaring the current epidemic as a "Public Health Emergency of International Concern". Controversy also emerged on the advisability of delaying or changing the location of the Olympic and Paralympic Games, which were held in August at various locations in Brazil. In this article, we review the available evidence on the risk of Zika and dengue virus infection in individuals who travel to endemic countries, especially for multitudinous events.
RESUMO
O objetivo deste trabalho foi apresentar a proposta metodológica denominada de "Pronta Resposta" modelada nas cidades de Belo Horizonte (Minas Gerais) e Natal (Rio Grande do Norte), Brasil. A metodologia visa identificar e delimitar áreas prioritárias para o direcionamento das ações de vigilância em tempo oportuno, buscando a redução da intensidade e velocidade da dispersão de epidemias em áreas urbanas endêmicas. Para tanto, a metodologia utiliza três variáveis, que representam as causas necessárias para a produção e reprodução da dengue: casos notificados (vírus), ovos de Aedes (vetor) e população (hospedeiro). Trata-se de um estudo ecológico que utilizou os dados dos três planos de informações agregados em escalas temporais e espaciais mais finas, de três a quatro semanas e grades de 400 a 600 metros respectivamente. As áreas de pronta resposta foram definidas por meio de análise estatística de varredura Scan, com definição de clusters espaciais simultâneos para os três planos por meio do programa SaTScan. Os resultados observados foram: na cidade de Natal, as áreas definidas como pronta resposta ocuparam em média 15,2% do território do município e concentraram 67,77% dos casos de dengue do período posterior ao utilizado na delimitação das áreas de pronta resposta, e em Belo Horizonte, os números observados foram de 64,16% dos casos em 23,23% do território. Esses resultados foram obtidos em duas cidades com realidades socioambientais e geográficas diferentes e com perfis epidemiológicos também distintos, apontando que a metodologia pode ser aplicada em diferentes realidades urbanas, criando a possibilidade de os programas de controle atuarem em porções reduzidas do território e impactar num alto percentual de casos em tempo oportuno.
The study aimed to present the methodological proposal entitled "Prompt Response", modelled in the cities of Belo Horizonte (Minas Gerais State) and Natal (Rio Grande do Norte State), Brazil. The proposal aims to identify and demarcate priority areas for timely targeting of surveillance activities, aiming to reduce the intensity and velocity in the spread of epidemics in endemic urban areas. The methodology uses three variables that represent the necessary causes for the production and reproduction of dengue: notified cases (virus), Aedes eggs (vector), and population (host). This was an ecological study that used data from three information planes aggregated in finer temporal and spatial scales of 3 to 4 weeks and 400 to 600-meter grids, respectively. The prompt response areas were defined by Scan statistical analysis with definition of simultaneous spatial clusters for the three planes via the SaTScan program. In Natal, the areas defined as prompt response occupied, on average, 15.2% of the city's territory and concentrated 67.77% of the dengue cases in the period following demarcation of the prompt response areas. In Belo Horizonte, the observed proportions were 64.16% of cases in 23.23% of the territory. These results were obtained in two cities with different socioenvironmental and geographic realities and distinct epidemiological profiles, indicating that the methodology can be applied to different urban realities, allowing control programs to concentrate on reduced portions of the territory and impacting a high percentage of cases in timely fashion.
El objetivo del trabajo fue presentar la propuesta metodológica, denominada de "Resposta Rápida", modelada en las ciudades de Belo Horizonte (Minas Gerais) y Natal (Rio Grande do Norte), Brasil. Esta última tiene como meta identificar y delimitar áreas prioritarias para la ejecución de acciones de vigilancia en el momento oportuno, buscando la reducción de la intensidad y velocidad de la dispersión de epidemias en áreas urbanas endémicas. Para tal fin, la metodología utiliza tres variables, que representan las causas necesarias para la producción y reproducción del dengue: casos notificados (virus), huevos de Aedes (vector) y población (huésped). Se trata de un estudio ecológico que utilizó los datos de los tres planos de información agregados en escalas temporales y espaciales más finas, de 3 a 4 semanas y tablas de 400 a 600 metros respectivamente. Las áreas de respuesta rápida se definieron a través del análisis estadístico de exploración Scan, con definición de clústeres espaciales simultáneos para los tres planos mediante el programa SaTScan. Los resultados observados fueron: en la ciudad de Natal, las áreas definidas como de respuesta rápida ocuparon de media un 15,2% del territorio del municipio y concentraron un 67,77% de los casos de dengue del período posterior al utilizado en la delimitación de las áreas de respuesta rápida y, en Belo Horizonte, los números observados fueron un 64,16% de los casos en un 23,23% del territorio. Estos resultados se obtuvieron en dos ciudades con realidades socioambientales y geográficas diferentes y con perfiles epidemiológicos también distintos, apuntando que la metodología se puede aplicar en diferentes realidades urbanas. Dando la posibilidad de que los programas de control actúen en secciones reducidas del territorio e impactar en un alto porcentaje de casos en el momento oportuno.

Método: Se realizó un estudio observacional, transversal, correlacional y con diseño no experimental. La población estuvo conformada por 325 estudiantes de tecnología médica y la muestra por 176 estudiantes de ambos sexos. El nivel de conocimiento se categorizó en deficiente, regular y alto. Mientras que las medidas preventivas se clasificaron en adecuadas e inadecuadas. El cuestionario contenía 23 preguntas de opción múltiple, validadas por juicio de expertos. Resultados: El 69,9 % de los estudiantes presentó un nivel de conocimientos regular, observándose medidas preventivas inadecuadas en el 44,3 %. Un 92,0 % de encuestados consideró que las arbovirosis son enfermedades graves, pero solo 10,2 % reconoció el signo de alarma del zika. Las principales medidas preventivas fueron: la fumigación (50,6 %) y el uso de repelentes (49,6 %). Además, el 92,6 % de estudiantes consideró importante eliminar los criaderos de mosquitos para evitar la propagación de los arbovirus. Sin embargo, solo el 51,1 % revisó la presencia de criaderos y limpió diaria e interdiariamente su domicilio (43,8 %). Conclusiones: El nivel de conocimientos fue regular y se relacionó con medidas preventivas inadecuadas como no revisar frecuentemente la presencia de criaderos de mosquitos ni realizar limpieza en las viviendas.
ABSTRACT Introduction: Arbovirus infections are a serious health problem in Peru. Higher population awareness and their participation in preventive activities can minimize their impact. Objective: Assessment on the level of knowledge and its relationship with preventive measures concerning arbovirus infections in university students in an endemic area of Peru, September to November 2020. Method: An observational, cross-sectional, correlational and non-experimental design study was carried out. The population consisted of 325 medical technology students and the sample consisted of 176 students of both sexes. The level of knowledge was categorized as deficient, regular and high. Preventive measures were classified as adequate and inadequate. The questionnaire contained 23 multiple-choice questions, validated by expert judgment. Results: The knowledge level in 69.9% of the students was fair, and inadequate preventive measures were observed in 44.3%. The 92.0% of surveyed personnel considered the arbovirus infection as a serious disease, but only 10.2% recognized the warning sign of zika. The main preventive measures were: fumigation (50.6%) and the use of repellents (49.6%). In addition, 92.6% of students considered as an important action the act to eliminate mosquito breeding sites in order to prevent the spread of infection. However, only 51.1% checked for the presence of breeding sites and cleaned their homes on a daily and inter-daily basis (43.8%). Conclusions: The level of knowledge was regular and was related to inadequate preventive measures such as not frequently checking for the presence of mosquito breeding sites and not cleaning houses.

Resultados: 69,9% dos alunos apresentaram nível regular de conhecimento, observando medidas preventivas inadequadas em 44,3%. 92,0% dos pesquisados consideraram que as arboviroses são doenças graves, mas apenas 10,2% reconheceram o sinal de alerta do Zika. As principais medidas preventivas foram: fumigação (50,6%) e uso de repelentes (49,6%). Além disso, 92,6% dos alunos consideraram importante eliminar os criadouros do mosquito para evitar a propagação de arboviroses. No entanto, apenas 51,1% verificaram a presença de criadouros e limparam suas casas diariamente e em dias alternados (43,8%). Conclusões: O nível de conhecimento foi regular e relacionado a medidas preventivas inadequadas, como não verificar com frequência a presença de criadouros do mosquito ou limpeza das residências.
RESUMO
A pesquisa analisa a produção de conteúdos sobre arboviroses na fanpage do Ministério da Saúde do Brasil antes, durante e após a epidemia de Zika vírus, com estudo de métodos mistos englobando análise do conteúdo divulgado entre 2015 e 2017 e o Discurso do Sujeito Coletivo (DSC) dos trabalhadores que produziam os conteúdos. Dos 5.732 posts coletados, 649 deles eram sobre arboviroses, com enfoque maior relacionado à prevenção e à Zika. O Sistema Único de Saúde (SUS) aparece em pequena parte da amostra. Há preocupação em comunicar saúde com qualidade e respaldo técnico, mas diferenças na linguagem do especialista e no timming entre o que é publicado on-line e o repassado aos serviços de saúde ocasionam ruídos. O discurso é transmissional, apresentando ausência de diálogo com a população, subestimando o potencial que a rede social tem para interação, compartilhamento e engajamento.(AU)

Existe la preocupación de comunicar salud con calidad y respaldo técnico, pero diferencias en el lenguaje del especialista y en el timing entre lo que se publica online y lo que se traspasa a los servicios de salud causan ruidos. El discurso es de transmisión, con ausencia de diálogo con la población, subestimando el potencial que la red social tiene para la interacción, compartición y compromiso.(AU)
This study analyses the content production about arboviruses on the fan page of the Brazilian Ministry of Health before, during and after the Zika virus epidemic. It uses a mixed methods study that comprises the content analysis released from 2015 to 2017 and the Collective Subject Discourse of the workers who produced the contents. The results show that 649 out of 5,732 posts collected addressed arboviruses, with a greater focus on prevention and Zika. The Brazilian National Health System (SUS) was found in a small part of the sample. There is a concern to inform about health with quality, but differences in the specialist's language and timing between what is published online and what is conveyed to technical health services cause communication noise. It is a transmissional discourse, with no dialogue with the population, underestimating the potential of social media for interaction, sharing and engagement.(AU)

Introducción: Las enfermedades arbovirales presentan un eleva incidencia y constituyen una amenaza permanente para la salud a escala mundial. Objetivo: Caracterizar epidemiológicamente los pacientes con sospecha clínica y diagnóstico de arbovirosis en la provincia Granma durante el 2019. Métodos: Se realizó un estudio observacional, descriptivo, transversal en el periodo comprendido entre el primero de enero y el 31 de diciembre de 2019. Las variables estudiadas fueron: edad, sexo, municipios, formas de identificación de signos y síntomas, positividad a dengue y meses de estudio de los pacientes. Resultados: En los casos estudiados por sospechas, el 41,43 por ciento pertenecía al municipio Bayamo y el 51,85 por ciento (9180) fueron pacientes femeninas. El rango de edad predominante fue ≤ 20 años (n = 8340; 47,10 por ciento). En el 87,07 por ciento (15417) de los pacientes la identificación de signos y síntomas sugerentes de arbovirosis fue mediante las pesquisas. La positividad a dengue se encontró en el 25,00 por ciento de los pacientes (4427), de los cuales el 53,87 por ciento (2385) fueron pacientes femeninas. El rango de edad más afectado por la arbovirosis fue el de 41-60 (n = 1422; 32,12 por ciento). El mes de septiembre fue el de mayor número de casos tanto estudiados por sospechas (n = 3720; 21,01 por ciento) como confirmados con dengue (n = 1341; 30,29 por ciento). En la provincia, la tasa de incidencia del dengue fue de 54,0 por cada 10 mil habitantes. Conclusiones: Se evidenció la importancia de las pesquisas como método para identificar signos y síntomas sugerentes de enfermedades arbovirales.

Este artigo apresenta um recorte dos resultados da experiência pedagógica realizada com estudantes por meio da interlocução entre saúde e escola, permeada pela educação e promoção da saúde enquanto potencializadores do protagonismo infantojuvenil. Trata-se de um estudo qualitativo, pesquisa-ação, realizado com 55 estudantes em minicursos em duas escolas municipais de Fortaleza (CE). Esta pesquisa versa sobre a implementação de uma abordagem ecossistêmica em ambiente escolar para a promoção da saúde, prevenção e controle do Aedes aegypti. Observa-se que as ações de controle contra o vetor dependerão de ampla participação de diversos grupos e comunidades. Os estudantes perceberam a necessidade de intensificar ações de promoção da saúde no cotidiano e promover o protagonismo e a autonomia dos sujeitos para coletivamente compreender a saúde como resultante das condições de vida para um desenvolvimento social mais equitativo. Conclui-se que o incremento de atividades dirigidas à mudança comportamental dos alunos, concentrando-se em componentes educativos, e a compreensão de que a saúde resulta de múltiplos determinantes alinham-se a uma articulação de ações de promoção de saúde fomentadoras de um saber coletivo, que estimula no indivíduo e na coletividade sua autonomia e emancipação para o cuidado de si e de seu entorno.
This paper presents the results of a pedagogical experience carried out with students via dialogue between healthcare and school, based on health education and promotion as potentiators of youth leadership. To investigate the implementation of an ecosystem approach in a school environment for health promotion, and Aedes aegypti control and prevention, a qualitative action research was carried out with 55 students attending mini-courses in two municipal schools in Fortaleza, Ceará, Brazil. Results show that action aimed at vector control depend on the broad participation of different groups and communities. Students realized the need to enhance daily health promotion actions and to promote youth leadership and autonomy to collectively understand health as a result of living conditions, seeking more equitable social development. In conclusion, the increased activities aimed at behavioral change, focusing on educational components, and the understanding that health results from multiple determinants, assumes an articulation of health promotion actions that foster collective knowledge to stimulate individual and community autonomy and emancipation in caring for themselves and their surroundings.

Introducción: El dengue es una infección viral endémica reemergente de notable preponderancia por su morbilidad y mortalidad, cuya incidencia se ha multiplicado en las últimos tiempos a nivel internacional. Objetivos: Caracterizar a pacientes con dengue según la clasificación revisada de la Organización Mundial de la Salud y determinar la correspondencia entre esta y la clasificación tradicional respecto a la gravedad de los casos. Métodos: Se realizó un estudio descriptivo y transversal en el Instituto de Medicina Tropical Pedro Kourí de La Habana durante el 2012, en el que se revisaron 247 historias clínicas seleccionadas por muestreo aleatorio estratificado. Resultados: En la casuística predominaron el dengue con signos de alarma, el grupo etario de 40-59 años, el sexo femenino y el síndrome de choque por dengue como principal forma clínica de gravedad. La fiebre estuvo presente en todos los afectados; también sobresalieron la cefalea, la astenia, las artromialgias, la exantema y el dolor retroocular. La leucopenia y la trombocitopenia constituyeron hallazgos muy frecuentes, al igual que la citólisis hepática; en tanto, las manifestaciones digestivas y hemorrágicas, entre otras, se asociaron significativamente con el desarrollo de dengue grave. Conclusiones: Se evidenció que utilizando la clasificación tradicional se hubiesen dejado de identificar y tratar adecuadamente a pacientes con dengue grave y dengue con signos de alarma, al catalogarse la mayoría de estos como fiebre del dengue, subestimando así la gravedad clínica de dichos casos.
Introduction: Dengue is a viral endemic reemerging infection of remarkable preponderance for its morbidity and mortality whose incidence has multiplied in the last times at international level. Objectives: To characterize patients with dengue according to the classification reviewed by the Health World Organization and to determine the correspondence between this and the traditional classification regarding the seriousness of the cases. Methods: A descriptive and cross-sectional study was carried out at Pedro Kourí Tropical Medicine Institute in Havana during 2012, in which 247 medical records were reviewed selected by stratified random sampling. Results: In the case material there was a prevalence of dengue with alarm signs, 40-59 age group, female sex and the shock syndrome due to dengue as the main clinic form of seriousness. The fever was present in all those affected; migraine, asthenia, artromialgias, exanthema and retroocular pain were also outstanding. The leukopenia and thrombocytopenia constituted very frequent findings, the same as hepatic cytolysis; as long as, the digestive and hemorrhagic manifestations, among others, were significantly associated with the development of serious dengue. Conclusions: It was evidenced that using the traditional classification the identification and appropriate treatment to patients with serious dengue and dengue with alarm signs would not be possible, when being classified most of these as fever of the dengue, underestimating this way the clinical seriousness of these cases.
