Colombia is an endemic country for dengue fever where the four serotypes of virus dengue (DENV1-4) circulate simultaneously, and all types are responsible for dengue cases in the country. The control strategies are guided by entomological surveillance. However, heterogeneity in aedic indices is not well correlated with the incidence of the disease in cities such as Riohacha, Bello and Villavice...

INTRODUCTION Hospitals are important for vector control of endemic diseases. METHODOLOGY To investigate the presence of dengue vectors, 30 locations at a university hospital in Cuiabá, Mato Grosso, Brazil, were monitored from January to December 2009 for mosquito eggs using ovitraps placed in high-traffic internal and external areas. RESULTS A total of 2,302 eggs were obtained. Positivity r...

Dengue and malaria are vector-borne diseases and major public health problems worldwide. Changes in climatic factors influence incidences of these diseases. The objective of this study was to investigate the relationship between vector-borne disease incidences and meteorological data, and hence to predict disease risk in a global outreach tourist setting. The retrospective data of dengue and ma...

Arboviruses transmitted by mosquitoes are a major cause of human disease worldwide. The absence of vaccines and effective vector control strategies has resulted in the need for novel mosquito control strategies. The endosymbiotic bacterium Wolbachia has been proposed to form the basis for an effective mosquito biocontrol strategy. Resident strains of Wolbachia inhibit viral replication in Droso...

Dengue presents a formidable and growing global economic and disease burden, with around half the world's population estimated to be at risk of infection. There is wide variation and substantial uncertainty in current estimates of dengue disease burden and, consequently, on economic burden estimates. Dengue disease varies across time, geography and persons affected. Variations in the transmissi...

Meteorological factors influence dengue virus ecology by modulating vector mosquito population dynamics, viral replication, and transmission. Dynamic modeling techniques can be used to examine how interactions among meteorological variables, vectors and the dengue virus influence transmission. We developed a dengue fever simulation model by coupling a dynamic simulation model for Aedes aegypti,...

Dengue is a vector transmitted viral infection; tropical and subtropical countries see outbreaks of dengue each year. There is a paucity of literature on effects of dengue infection on pregnancy outcome and this prompted us to undertake a study for better understanding of pregnancy implications with dengue infection. Pregnant women admitted during the seasonal outbreak of dengue between Septemb...

Dengue viral infection (DVI) is amongst a big Global health challenges. The clinical manifestations of disease ranges from subclinical Dengue fever (DF) to the complicated dengue haemorrhagic fever (DHF) and dengue shock syndrome (DSS). Reason behind this is the absence of specific tetravalent vaccine and the anti virals. The mortality rate with the infection might exceed upto 5%. Therefore, th...

Dengue is an important tropical infection. The Aedes spp is the main vector of this deadly viral disease. Each year, there are several cases of infection from the tropical countries around the world and there are many deaths due to infection1. Of interest, the mosquito vector bites not only human beings but also other animals. According to the study by Barrera et al2, dog is the second most com...
