Dengue is caused by virus is also known as break bone fever. Dengue is spread by numerous mosquito species of Aedes group. Dengue attacked mostly in tropical countries. Unfortunately dengue has also becomes dengue hemorrhagic fever, which leads bleed from under skin or nose. It can turn dengue shock disorder which causes substantial shock and bleed. There is no precise cure and no vaccine avail...

Dengue is considered to be the most important mosquito-borne viral disease in the world. The Aedes aegypti mosquito, its vector, is highly anthropophilic and is very well adapted to urban environments. Although several vaccine candidates are in advanced stages of development no licensed dengue vaccine is yet available. As a result, controlling the spread of dengue still requires that mosquitoes...

BACKGROUND & OBJECTIVES Dengue is an arboviral disease of public health importance in many parts of India and recently many cases have been reported from northeastern India. Aedes mosquitoes, which are the vectors of dengue, are widely prevalent in the region. A study was initiated in Sonitpur district of Assam to understand the spatiotemporal distribution and seasonal prevalence of dengue vect...

Dengue and dengue hemorrhagic fever are mosquito-borne viral diseases that coincide with the distribution of Aedes aegypti (L.), the primary vector in the tropical and semitropical world. With no available vaccine, controlling the dengue vector is essential to avoid epidemics. This study evaluates the efficacy of a new smoke-generating formulation containing pyriproxyfen and permethrin in Puert...

BACKGROUND A dengue early warning system aims to prevent a dengue outbreak by providing an accurate prediction of a rise in dengue cases and sufficient time to allow timely decisions and preventive measures to be taken by local authorities. This study seeks to identify the optimal lead time for warning of dengue cases in Singapore given the duration required by a local authority to curb an outb...

background: dengue fever is a serious public health issue in pakistan for many years. globally plants have been reported to contain compounds with insecticidal properties. these properties have been demonstrated more recently on the larval stages of mosquitoes. therefore, citrus cultivar seeds were evaluated for larvicidal potential against the primary dengue vector aedes aegypti . methods: ext...

challenging global public health, ranging from self-limiting dengue fever to more severe life-threatening form termed as dengue hemorrhagic fever. In the last 50 yr, its worldwide incidence increased by 30 fold and it was estimated that 1/3 to 1/2 of the world’s population is at risk of becoming infected. Currently, epidemic dengue hemorrhagic fever is a leading cause of hospitalization and dea...

The only way for dengue to spread in the human population is through the human-mosquito-human cycle. Most research in this field discusses the dengue-mosquito or dengue-human relationships over a particular study area, but few have explored the local spatial variations of dengue-mosquito and dengue-human relationships within a study area. This study examined whether spatial heterogeneity exists...

BACKGROUND Although a vaccine could be available as early as 2016, vector control remains the primary approach used to prevent dengue, the most common and widespread arbovirus of humans worldwide. We reviewed the evidence for effectiveness of vector control methods in reducing its transmission. METHODOLOGY/PRINCIPAL FINDINGS Studies of any design published since 1980 were included if they eva...

Dengue is considered one of the most important vector-borne infection, affecting almost half of the world population with 50 to 100 million cases every year. In this paper, we present one of the simplest models that can encapsulate all the important variables related to vector control of dengue fever. The model considers the human population, the adult mosquito population and the population of ...
