by Leigh R. Bowman, Joacim Rockl öv, Axel Kroeger, Piero Olliaro, Ronald Skewes BackgroundAedes-borne arboviruses continue to precipitate epidemics worldwide. In Dominican Republic, the appearance of Zika virus cases that closely followed a large dengue epidemic provided an opportunity to study the different transmission drivers behind these two flaviviruses. Retrospective datasets were used to collect information on the populations at risk and descriptive statistics were used to describe the outbreaks on a national scale. Methodology/ Principal findingsExpectedly, box plots showed that 75% of dengue was reported in those aged

di N, Martinez-Chapa SO Abstract Current review article focuses on Dengue, which is one of the most fatal infectious illnesses and is considered to be a worldwide threat. The paper covers essential topics including an overview on neglected tropical diseases with specific emphasis on Dengue fever, mosquito's cycle of life and mechanism of infection, adaptive response, and different stages in Dengue immunopathogenesis. The current work is also dedicated to the thorough study of Dengue outbreak across the globe with narrowed study to tropical and subtropical regions. Moreover, this review article demonstrates the cor...

Abstract Vectors are living organisms that transmit infectious diseases from an infected animal to humans or another animal. Biological vectors such as mosquitoes, ticks, and sand flies carry pathogens that multiply within their bodies prior to delivery to a new host. The increased prevalence of vector-borne diseases (VBDs) such as Aedes-borne dengue, Chikungunya (CHIKV), Zika (ZIKV), malaria, tick-borne disease (TBD), and scrub typhus has a huge impact on the health of both humans and livestock worldwide. In particular, zoonotic diseases transmitted by mosquitoes and ticks place a considerable burden on public h...

[Foroyaa] Information coming from the sister Republic of Senegal, report an outbreak of 'Dengue', a viral disease spread by mosquitoes. The outbreak is said to have been first reported in late September in the Fatick region of Senegal, but this has since spread to the rest of that country. Latest reports indicate that tens of cases have been reported in the Fatick, Diourbel, Saint Louis and Louga Regions of Senegal, and the Government of President Maki Sall, has embarked on a vigorous fumigation campaign aimed at el

Conclusion The results obtained from this research shows, in general, the fragility in the social and political infrastructure necessary to improve the living conditions of populations, particularly those that depend on family agriculture in drought prone areas. The conditions of social, economic and environmental vulnerabilities presented in the region can be amplified by the drought process, and can aggravate the impacts resulting drought events, thus disadvantaging the population of this region, as shown in the Fig. 1. The general perception of the interviewees of the health sector shows an agreement with what is found...

In this study, we investigated the seroprevalence of DENV infection in two districts of Kaohsiung City, a metropolis in southern Taiwan, where major dengue outbreaks have occurred in the past three decades. We enro lled 1,088 participants from the Sanmin and Nanzih districts after the dengue outbreak of 2015, the largest in Taiwan since World War II, and found an overall DENV seroprevalence of 12.4% (95% confidence interval: 10.5–13.4%) based on the InBios DENV IgG ELISA kit. The ratios of clinically inappar ent to symptomatic infections were 2.86 and 4.76 in Sanmin and Nanzih districts, respectively. Consistent with...

Becnel Recent outbreaks of locally transmitted dengue and Zika viruses in Florida have placed more emphasis on integrated vector management plans forAedes aegypti (L.) andAedes albopictus Skuse. Adulticiding, primarily with pyrethroids, is often employed for the immediate control of potentially arbovirus-infected mosquitoes during outbreak situations. While pyrethroid resistance is common inAe.aegypti worldwide and testing is recommended b...

Abstract India witnessed dengue outbreaks during 2017 in different parts with more than 180000 cases. There is no data on the serotypes/genotypes of dengue virus (DENV) associated with the 2017 outbreak season. The present study investigated DENV circulating in Pune and Nashik regions of Maharashtra, Western India at molecular level. IgM negative samples that were collected before 6th post onset days of illness were tested for DENV RNA and serotyped by real time RT-PCR based methods. Representative samples of each serotype were processed for virus isolation and envelope (E) gene sequencing. Among the 472 samples t...

AbstractPurpose of ReviewWeather and climate influence multiple aspects of infectious disease ecology. Creating and applying early warning systems based on temperature, precipitation, and other environmental data can identify where and when outbreaks of climate-sensitive infectious diseases could occur and can be used by decision makers to allocate resources. Whether an outbreak actually occurs depends heavily on other social, political, and institutional factors.Recent FindingsImproving the timing and confidence of seasonal climate forecasting, coupled with knowledge of exposure-response relationships, can identify prior ...

This report summarizes surveillance data reported to CDC from U.S. states in 2017 for nationally notifiable arboviruses. It excludes dengue, chikungunya, and Zika viruses because, in the continental United States, these viruses are acquired primarily through travel. In 2017, 48 states and the District of Columbia (DC) reported 2,291 cases of domestic arboviral disease, including 2,097 (92%) WNV disease cases. Among the WNV disease cases, 1,425 (68%) were classified as neuroinvasive disease (e.g., meningitis, encephalitis, or acute flaccid paralysis), for a national rate of 0.44 cases per 100,000 population.
