PLOS 23/09/20 The COVID-19 pandemic should not jeopardize dengue control. Author summary The concurrent circulation of dengue and coronavirus disease 2019 (COVID-19) may produce many unfavourable outcomes—such as co-infections; delays in diagnosis, treatment, and mitigation measures; overwhelming of the healthcare system; underreporting of cases; deterioration in surveillance and control interventions; and exacerbation of social inequalities.
Résumé traduit : La circulation simultanée de la dengue et de la maladie à coronavirus 2019 (COVID-19) peut produire de nombreux résultats défavorables, tels que des co-infections; retards dans le diagnostic, le traitement et les mesures d'atténuation; écrasement du système de santé; sous-déclaration des cas; détérioration des interventions de surveillance et de contrôle; et l'exacerbation des inégalités sociales. En effet, le verrouillage compromet grandement l'efficacité de la lutte antivectorielle, en particulier les campagnes de mobilisation sociale et la pulvérisation préventive d'insecticide dans les espaces privés (pulvérisation intérieure et péridomestique). Ainsi, le fait de ne pas mettre en œuvre de manière appropriée la gamme complète des interventions de lutte antivectorielle peut entraîner une réduction de leur efficacité globale et un risque accru de maladies à transmission vectorielle. Par conséquent, la communauté de la santé et les décideurs politiques devraient développer des politiques proactives et allouer des ressources adéquates pour prévenir et gérer la résurgence de la dengue et d'autres maladies à transmission vectorielle dans la nouvelle ère du COVID-19. – guatemalt
Indeed, lockdown is greatly compromising the effectiveness of vector control, especially social mobilization campaigns and preventive insecticide spraying in private spaces (indoor and peridomestic spraying).
Thus, failure to appropriately implement the full range of vector control interventions can lead to a reduction in their overall effectiveness and an increasing risk of vector-borne diseases circulating.

Received: 26 February 2019 / Revised: 21 March 2019 / Accepted: 2 April 2019 / Published: 4 April 2019 : In this paper, we report an application for the mathematical theory of dynamic optimization for design of optimal strategies that account for daily commuting of human residents, aiming to reduce vector-borne infections (dengue) among human populations.
Our analysis is based on a two-patch dengue transmission model amended with control variables that represent personal protection measures aimed at reduction of the number of contacts between mosquitoes and human hosts (e.g., the use of repellents, mosquito nets, or insecticide-treated clothing). As a result, we have proposed and numerically solved an optimal control problem to minimize the costs associated with the application of control measures, while also minimizing the total number of dengue-infected people in both residential areas.

Abstract Dengue is a mosquito-borne disease that threatens over half of the world’s population.
Despite being endemic to more than 100 countries, government-led efforts and tools for timely identification and tracking of new infections are still lacking in many affected areas. Multiple methodologies that leverage the use of Internet-based data sources have been proposed as a way to complement dengue surveillance efforts.

PLOS 21/02/17 Dengue virus antibody database: Systematically linking serotype-specificity with epitope mapping in dengue virus. Abstract Background A majority infections caused by dengue virus (DENV) are asymptomatic, but a higher incidence of severe illness, such as dengue hemorrhagic fever, is associated with secondary infections, suggesting that pre-existing immunity plays a central role in dengue pathogenesis.
Primary infections are typically associated with a largely serotype-specific antibody response, while secondary infections show a shift to a broadly cross-reactive antibody response.

Received: 18 January 2016 / Revised: 21 March 2016 / Accepted: 25 March 2016 / Published: 29 March 2016 Dengue is a viral disease caused by a flavivirus that is transmitted by mosquitoes of the genus Aedes. There is currently no specific treatment or commercial vaccine for its control and prevention; therefore, mosquito population control is the only alternative for preventing the occurrence of dengue. For this reason, entomological surveillance is recommended by World Health Organization (WHO) to measure dengue risk in endemic areas; however, several works have shown that the current methodology (aedic indices) is not sufficient for predicting dengue.

In 2013, 541 cases of dengue fever were reported in travellers returning from dengue-affected countries, an overall increase of 58% compared to 2012. India and Thailand continue to be the most frequent countries of travel reported for dengue cases, although in 2013, there was also an increase in cases associated with travel to Barbados. There was also an increase in chikungunya with 24 cases reported in 2013 compared to 15 cases in 2012, mostly acquired in India and South East Asia.
In December 2013, indigenously acquired chikungunya was first reported in St Martin, a French overseas territory in the Caribbean. PLOS 30/09/14 Characteristics of a Dengue Outbreak in a Remote Pacific Island Chain – Republic of the Marshall Islands, 2011–2012. Abstract Dengue is a potentially fatal acute febrile illness caused by four mosquito-transmitted dengue viruses (DENV-1–4).
Although dengue outbreaks regularly occur in many regions of the Pacific, little is known about dengue in the Republic of the Marshall Islands (RMI). To better understand dengue in RMI, we investigated an explosive outbreak that began in October 2011. Suspected cases were reported to the Ministry of Health, serum specimens were tested with a dengue rapid diagnostic test (RDT), and confirmatory testing was performed using RT-PCR and IgM ELISA.
EUROSURVEILLANCE 16/10/14 Concurrent outbreaks of dengue, chikungunya and Zika virus infections – an unprecedented epidemic wave of mosquito-borne viruses in the Pacific 2012–2014. Since January 2012, the Pacific Region has experienced 28 new documented outbreaks and circulation of dengue, chikungunya and Zika virus. These mosquito-borne disease epidemics seem to become more frequent and diverse, and it is likely that this is only the early stages of a wave that will continue for several years. Improved surveillance and response measures are needed to mitigate the already heavy burden on island health systems and limit further spread to other parts of the world. Since January 2012, the Pacific is experiencing a high burden of mosquito-borne disease due to concurrent epidemics of dengue, chikungunya and Zika virus infections.
So far over 120,000 people have been reported to be affected, a figure that is likely to substantially underestimate the real numbers due to underreporting. PLOS 20/11/14 Approaches to Refining Estimates of Global Burden and Economics of Dengue. Results Dengue burden data and sources of variability Estimates of the disease and economic burden of dengue were derived by combining surveillance, clinical, and cost data. Since dengue is a reportable disease in many endemic countries, the incidence of dengue in a population can be estimated initially from cases reported to the surveillance system.
But because surveillance systems are not designed to capture all episodes of symptomatic dengue, relatively low reporting rates lead to conservative incidence estimates –. Further, national dengue reporting systems show great diversity in design and implementation, and some developing countries have important resource limitations that hamper their ability to produce any systematic dengue-related data. To illustrate, there were about 2.2 million reported episodes of dengue illnesses to WHO in 2010, but estimates of total symptomatic dengue incidence vary widely.

Abstract Background Dengue is a growing problem both in its geographical spread and in its intensity, and yet current global distribution remains highly uncertain. Challenges in diagnosis and diagnostic methods as well as highly variable national health systems mean no single data source can reliably estimate the distribution of this disease. As such, there is a lack of agreement on national dengue status among international health organisations. Here we bring together all available information on dengue occurrence using a novel approach to produce an evidence consensus map of the disease range that highlights nations with an uncertain dengue status. Methods/Principal Findings A baseline methodology was used to assess a range of evidence for each country.
