BACKGROUND Dengue is a mosquito-borne infectious disease that constitutes a growing global threat with the habitat expansion of its vectors Aedes aegyti and A. albopictus and increasing urbanization. With no effective treatment and limited success of vector control, dengue vaccines constitute the best control measure for the foreseeable future. With four interacting dengue serotypes, the develo...

This study evaluates the results of an educational campaign developed in an outlying neighborhood of São José do Rio Preto, São Paulo, and the relationship between the population's knowledge and habits. Prior to and after the educational activities, samples were taken to measure level of knowledge concerning dengue and its vectors, breeding sites, and control measures. Potential breeding sites ...

BACKGROUND Travelers who acquire dengue infection are often routes for virus transmission to other regions. Nevertheless, the interplay between infected travelers, climate, vectors, and indigenous dengue incidence remains unclear. The role of foreign-origin cases on local dengue epidemics thus has been largely neglected by research. This study investigated the effect of both imported dengue and...

Dengue fever is currently one of the most important mosquito-borne diseases that affect humans. With neither vaccines nor treatment available, prevention of the disease relies heavily on surveillance and control of mosquito vectors. In the present study, we have evaluated and showed the potential use of the Dengue NS1 Ag Strip(®) for the detection of dengue virus (DENV) in Aedes aegypti. Initia...

Background: Dengue, chikungunya, and Zika viruses are emerging infectious disease threats wherever suitable vectors, hosts, and habitat are present. The aim of the present study was to use the bioagent transport and environmental modeling system (BioTEMS) to identify the potential for arbovirus-infected Aedes species to invade the Chabahar area in southeastern Iran. Methods: ArcGIS geospatial a...

BACKGROUND Mathematical models have been used to study the dynamics of infectious disease outbreaks and predict the effectiveness of potential mass vaccination campaigns. However, models depend on simplifying assumptions to be tractable, and the consequences of making such assumptions need to be studied. Two assumptions usually incorporated by mathematical models of vector-borne disease transmi...

Malaria and dengue are major public-health problems in Latin America. Malaria is transmitted in 21 countries in the region with over 885,000 cases in 2002. Ninety-five percent of the cases occur in the Amazonian countries, mainly in Brazil. The main malaria vectors in Mexico, Central America and Northern South America are Anopheles albimanus and An. pseudopunctipennis, and An. darlingi and An. ...

The first part of this project include the surveillance of dengue vectors, ovitrap collection, and source reduction in southern Taiwan. In addition to Kaoshung, Pingtung and Tainan counties, none Aedes aegypti (AE) vector was found in the areas around 30km of tropic cancer at west southern of Taiwan. Meanwhile AE can only be found in 3 Li of Taitung city and 3 Li in MaKo city of Pescadores. Low...

UNLABELLED BACKGROUND & OBJECTIVESI: Transovarial transmission of dengue virus in the Aedes vectors is now a well-documented phenomenon reported from many parts of the endemic areas in the world, which played an important role in initiating and maintaining the outbreak in human populations. This study investigated the factors affecting breeding habitats and the relationship with transovarial de...
