Dengue caused by four antigenically distinct serotype remains a serious health concern around the world, particularly in the tropical areas. Clinical signs and symptoms of this disease are indistinguishable from other infectious disease; therefore, laboratory diagnosis is very crucial for confirming the disease that will be useful for the patient’s management. In laboratory, dengue can be confirmed using cell culture, RNA detection, and serological detection based on ELISA and immunochromatographic test. However, each of these methods has certain practical limitations. Therefore, researchers from all over the world have been working to address these limitations. In this chapter, we will highlight the current research toward the development of novel point-of-care test for the diagnosis of dengue in acute and convalescent phase.
由四种抗原性不同的血清型引起的登革热仍然是世界各地,特别是热带地区严重的健康问题。该病的临床体征和症状与其他传染病难以区分;因此,实验室诊断对于确认疾病非常重要,这将有助于患者的管理。在实验室,登革热可通过细胞培养、RNA检测和基于ELISA和免疫层析试验的血清学检测来确诊。然而,每种方法都有一定的实际局限性。因此,来自世界各地的研究人员一直在努力解决这些限制。在这一章中,我们将重点介绍目前的研究,以发展新的点护理测试诊断登革热在急性和恢复期。

Dengue Fever or commonly known as Dengue, a mosquito-borne arboviral infection has emerged as havoc around the globe. Annually, about 50 million infections are reported, resulting in 22,000 deaths and almost 2.5 billion people are reported living at risk. Dengue infection is caused by Dengue Virus (DENV), which is a member of genus Flavivirus and comprised of ten proteins; three proteins, capsid (C), membrane (M), and envelope (E), play structural role and seven are identified as non-structural that direct DENV replication. Four distinct serotypes: DENV-1, DENV-2, DENV-3 and DENV-4 are transmitted via Aedes mosquitoes. Clinically, Dengue patients can be categorized into three groups according to WHO 2009 revised classification. Typical symptoms of dengue include: extreme fatigue; sudden fever (from 3-7 days), headache, joint, muscle, and back pain; vomiting and diarrhea, appetite loss; skin rash along minor bleeding. Aedes aegypti is geographically distributed in tropical areas and breeds in artificially filled water containers i.e. drums, tyres, flower vases plastic food containers, tin cans, etc. Due to four viral serotypes and non-availability of the model animal for dengue, producing vaccines is a challenging task. Thus, Dengue can be managed using various vector control strategies through physical, chemical and biological means.
登革热,俗称登革热,是一种由蚊子传播的虫媒病毒感染,已经在全球范围内肆虐。据报告,每年约有5 000万例感染,造成22 000人死亡,近25亿人生活在危险之中。登革热感染是由登革热病毒(DENV)引起的,登革热病毒是黄病毒属的一个成员,由十种蛋白质组成;衣壳(C)、膜(M)和包膜(E)三种蛋白起结构性作用,其中7种被确定为指导DENV复制的非结构性蛋白。四种不同的血清型:DENV-1、DENV-2、DENV-3和DENV-4通过伊蚊传播。临床上,根据世卫组织2009年修订的分类,登革热患者可分为三组。登革热的典型症状包括:极度疲劳;突然发热(3-7天)、头痛、关节、肌肉和背部疼痛;呕吐腹泻,食欲不振;皮疹伴少量出血。埃及伊蚊在地理上分布于热带地区,并在人工装满水的容器(如鼓、轮胎、花瓶、塑料食品容器、锡罐等)中繁殖。由于登革热病毒有四种血清型,而且无法获得登革热模型动物,因此生产疫苗是一项具有挑战性的任务。因此,可以通过物理、化学和生物手段使用各种病媒控制战略来控制登革热。

According to the Pan American Health Organization (PAHO) reports, the annual average number of dengue cases in the Americas has been 1,579,658 in the last 8 years (2010 – 2017), affecting the population ’ s welfare. The high level in dengue cases does not only have an impact from an epidemiological perspective but also from an economical perspective as the treatment cost that must be borne. The aim of this chapter is to review the situation as reported in the American countries with the highest number of cases, focusing on the burden of the disease (measured in DALYs and number of cases) and its total treatment cost, which includes direct (medical and non-medical) costs and indirect costs. We calcu- late the total treatment cost per DALY for the epidemic year (2015). The results show that Mexico has the highest cost per DALY (US$ 17,703) followed by Brazil (US$ 11,218), Colombia (US$ 4,540), and the Dominican Republic (US$ 1,157). Additionally, after adjusting for total health expenditure, we found all the countries exhibit a similar share of total treatment cost over health expenditure (0.16% in average).
根据泛美卫生组织(PAHO)的报告,在过去8年(2010 - 2017年)中,美洲每年平均登革热病例数为1,579,658例,影响了人口的福利。登革热病例的高水平不仅从流行病学角度产生影响,而且从经济角度也产生影响,因为必须承担治疗费用。本章的目的是审查病例数最多的美洲国家所报告的情况,重点是疾病负担(以伤残调整生命年和病例数衡量)及其总治疗费用,其中包括直接(医疗和非医疗)费用和间接费用。我们计算了流行病年(2015年)的每个DALY的总治疗费用。结果显示,墨西哥的每DALY成本最高(17703美元),其次是巴西(11218美元)、哥伦比亚(4540美元)和多米尼加共和国(1157美元)。此外,在调整卫生总支出后,我们发现所有国家的总治疗费用占卫生总支出的比例相似(平均为0.16%)。

Laboratory Tests Used in the Diagnostic and Research of Dengue Virus: Present and Future 用于登革热病毒诊断和研究的实验室检测:现在和未来

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, bac -teria, 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. molecular techniques, and others. tubes, 6–96 well culture plates, and oth ers are used in order to sustain the binding to cell cultures. A modified shell vial technique allows the recovery of a higher number of YFV, SLV, WNV, ILHV, GCV, OROV, MAYV and DENV isolations. This technique follows the same steps as a standard method, but after inoculating cells, the cultures are centrifuged to velocities between 1800 and 2200 rpm. This technique can also be used to isolate DENV coinfections. However, it seems not to have good results for VEE isolation [19–22].
登革热是一个重大的公共卫生问题。已确定四种登革热病毒血清型;然而,由于存在许多病毒、细菌和寄生虫,产生相同的临床表现,出现在同一地理区域,甚至产生合并感染,因此诊断困难。因此,确定一个人是否已经、曾经或正在感染登革热病毒是非常重要的。为此,已经开发了直接和间接的实验室测试,以确定通常检测抗体反应的病毒或其结构的一部分。这些技术用于诊断、流行病学研究、监测、评估和生产疫苗和抗病毒药物等。它们的范围从使用细胞培养、动物模型、昆虫接种和血清学测试,到使用检测分子测试和遗传物质定量,本章将对此进行描述,并简要说明该方法、其优缺点及其在登革热研究中的应用。分子技术等等。使用试管,6-96孔培养板和其他工具来维持与细胞培养物的结合。改进的壳瓶技术可以回收更多的YFV、SLV、WNV、ILHV、GCV、OROV、MAYV和DENV分离株。该技术遵循与标准方法相同的步骤,但在接种细胞后,将培养物离心至1800至2200 rpm之间。该技术也可用于分离登革热病毒共感染。然而,对VEE的分离效果似乎不太好[19-22]。

Dengue is a vector-borne disease that risks two-thirds of the world ’ s population particularly in tropical and subtropical regions. Strategies have been implemented, but they are only effective in the short term. A new innovative and promising strategy against dengue is by the use of Wolbachia bacterium. This requires that Wolbachia -carrying mosquitoes should persist in the population. To assess the persistence of Wolbachia -carrying mosquitoes and its effects on dengue, a number of mathematical models have been formulated and analysed. In this chapter, we review the existing mathematical models of Wolbachia carrying mosquito population dynamics and dengue with Wolbachia intervention and provide examples of the mathematical models. Simulations of the models are presented to illustrate the model ’ s solutions.
登革热是一种媒介传播疾病,威胁着世界三分之二的人口,特别是在热带和亚热带地区。已经实施了一些战略,但它们只在短期内有效。利用沃尔巴克氏菌是防治登革热的一种新的创新和有前途的战略。这就要求携带沃尔巴克氏体的蚊子在种群中持续存在。为了评估携带沃尔巴克氏体的蚊子的持久性及其对登革热的影响,已经制定和分析了许多数学模型。在这一章中,我们回顾了沃尔巴克氏体携带蚊种群动态和沃尔巴克氏体干预登革热的现有数学模型,并提供了数学模型的实例。通过对模型的仿真来说明模型的解。

Urban Ecology and the Effectiveness of Aedes Control 城市生态与伊蚊控制效果
Pub Date : 2018-11-05 DOI: 10.5772/INTECHOPEN.78688
Wladimir J Alonso, B. McCormick
Past initiatives to control Aedes mosquitoes were successful, in part because they implemented draconian top-down control programs. To achieve similar results now, explicit recognition of the complexity in urban ecologies in terms of land ownership, law enforcement and accessibility for control interventions are required. By combining these attributes, four classes of spaces, along with corresponding control strategies, are suggested to better target Aedes species population control efforts. On one end of the spectrum there are accessible and accountable spaces (e.g. backyards and closely managed public facilities), where interventions can rely predominantly on bottom-up strategies with the local population playing the principle role in the implementation of actions, but with government coordination. On the other end of the spectrum are inaccessible and unaccountable spaces, which require top-down and extensive approaches. By identifying these and the intermediate classes of space, government and private resources can be allocated in a more efficient customized manner. Based on this new framework, a set of actions is proposed that might be implemented in dengue and other Aedes -borne crises. The framework considers existing limitations and opportunities associated with modern societies – which are fundamentally different from those associated with the successful control of Aedes species in the past.
过去控制伊蚊的举措是成功的,部分原因是它们实施了严厉的自上而下的控制计划。现在要取得类似的结果,就需要明确认识到城市生态在土地所有权、执法和控制干预措施的可及性方面的复杂性。结合这些特征,提出了4类空间类型和相应的控制策略,以更好地控制伊蚊种群数量。一方面是可访问和可问责的空间(例如后院和受到严密管理的公共设施),在这些空间中,干预措施可以主要依靠自下而上的战略,由当地居民在行动实施中发挥主要作用,但需要政府协调。在光谱的另一端是无法进入和无法解释的空间,这需要自上而下和广泛的方法。通过确定这些和中间类别的空间,政府和私人资源可以以更有效的定制方式进行分配。根据这一新框架,提出了一套可在登革热和其他伊蚊传播危机中实施的行动。该框架考虑了与现代社会相关的现有限制和机会,这些限制和机会与过去成功控制伊蚊物种相关的限制和机会根本不同。

Aedes aegypti (Stegomyia) has been human vectors for many human diseases globally. In recent years, dengue virus has been diagnosed in different regions such as Asia and Latin America vectored by Aedes spp. mosquitoes. Dengue cases have been reported again in the several parts of African and other continental hospital. The different types of breed - ing sites have been found to be abundant in both urban and rural areas. The abundance of adult Ae. aegypti and habitat productivity in different settings escalates the risk of dengue transmission if viruses are found in asymptomatic population. The insecticide resistance has been found to occur in the wild population of Aedes aegypti to insecticides commonly used for indoor residual spray and long-lasting insecticidal net treatments. The control of human vector population is still a challenge as the vector has a diurnal feeding and outdoor resting behavior. Environmental management is still the best practice to be adopted in many countries for Aedes aegypti control. The currently discovered dengue vaccine might be an immediate arsenal for the community immunization.
埃及伊蚊(隐蚊)是全球许多人类疾病的人类媒介。近年来,登革热病毒已在亚洲和拉丁美洲等不同地区被诊断出来,媒介是伊蚊。在非洲和其他大陆医院的几个地区再次报告了登革热病例。在城市和农村都发现了大量不同类型的繁殖场所。成年伊蚊的丰度。如果在无症状人群中发现病毒,不同环境下的埃及伊蚊和栖息地生产力会增加登革热传播的风险。已发现埃及伊蚊野生种群对常用于室内残留喷雾和长效杀虫蚊帐处理的杀虫剂产生抗药性。媒介生物具有昼夜摄食和室外休息行为,对媒介生物种群的控制仍是一项挑战。环境管理仍然是许多国家控制埃及伊蚊的最佳做法。目前发现的登革热疫苗可能成为社区免疫的直接武器。

The abundance of adult Ae. aegypti and habitat productivity in different settings escalates the risk of dengue transmission if viruses are found in asymptomatic population.

Dengue is a disease caused by the dengue virus (DENV), being the most important arbovirus in the world. About 3.97 billion people live in countries at risk and 400 million infections occur each year, of which 500,000 suffer from the most severe form of the disease and 25,000 of these die. The clinical spectrum of Dengue ranges from asymptomatic infection to severe Dengue characterized by increased vascular permeability, bleeding disorders, shock, and death. The increase in global cases of this disease is due in part to the absence of effective public intervention measures and lack of a specific treatment and vaccines licensed for human use. Therefore, in this review, we will present the different strategies known to date for the development of vaccines for this disease, as well as the results and limitations obtained in the different clinical studies.
登革热是由登革热病毒(DENV)引起的疾病,是世界上最重要的虫媒病毒。大约39.7亿人生活在有风险的国家,每年发生4亿次感染,其中50万人患有最严重的疾病,其中25 000人死亡。登革热的临床症状范围从无症状感染到以血管通透性增加、出血性疾病、休克和死亡为特征的严重登革热。全球病例增加的部分原因是缺乏有效的公共干预措施,缺乏专门的治疗方法和获准供人使用的疫苗。因此,在这篇综述中,我们将介绍迄今为止已知的用于开发这种疾病疫苗的不同策略,以及在不同临床研究中获得的结果和局限性。
