Dengue is a viral infectious fever that is transmitted by Aedes mosquitoes (Diptera: Culicidae) causing a significant health burden in tropical countries since several decades. Severe complications such as dengue hemorrhage fever can develop and lead to fatal outcomes throughout the globe. Mosquito Aedes albopictus Skuse is an effective vector for dengue viruses both in its spread and transmiss...

In 2001, a major dengue outbreak was recorded in Chennai city, with 737 cases (90%) out of a total of 861 cases recorded from Tamil Nadu state. A KAP survey was carried out to assess the community knowledge, attitude and practice on dengue fever (DF), following the major dengue outbreak in 2001. A pretested, structured questionnaire was used for data collection. The multistage cluster sampling ...

Dengue is a vector-borne disease recognized as the major arbovirose with four immunologically distant dengue serotypes coexisting in many endemic areas. Several mathematical models have been developed to understand the transmission dynamics of dengue, including the role of cross-reactive antibodies for the four different dengue serotypes. We aimed to review deterministic models of dengue transm...

Dengue is one of the vector borne viral disease prevalent worldwide. During the last half a century, the incidence of dengue has increased by 30-fold and expanded to many new countries, and also from urban areas to rural areas (WHO 2009). It is estimated approximately 294 million in apparent dengue infections and about 96 million apparent dengue infections occurred worldwide in 2010, and Asia h...

PROBLEM In 2010, dengue virus (DENV) serotype-4 was detected during a dengue outbreak in the Amazonian city of Boa Vista. At that time Brazil was already endemic for DENV-1, DENV-2 and DENV-3. This was the first time DENV-4 was observed in the country after it was initially detected and eliminated in 1981. APPROACH To hinder the spread of DENV-4 throughout Brazil, standard vector control meas...

Dengue usually presents itself with subclinical or mild infection to full blown dengue fever (DF) to dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). In Kolkata, dengue started in 1824 followed by five epidemics that occurred in 1836, 1906, 1911, 1923 and 2005. The aim of this investigation is to study the clinicohematological correlation of all patients with respect to their gen...

BACKGROUND Socio-economic, demographic factors and Knowledge Attitude Practices (KAPs) have been recognized as critical factors that influence the incidence and transmission of dengue epidemics. However, studies that characterize above features of a risk free or low risk population are rare. Therefore, the present study was conducted to characterize the household related, demographic, socio-eco...

In Vietnam, dengue hemorrhagic fever has been detected since the 1950s. In Southeast Asia, urban centers expanded rapidly in an uncontrolled and unplanned way. The Aedes aegypti populations and dengue viruses thrived in these new ecological and demographic settings. The result of these changes was a greatly extended geographic distribution, increased densities of Ae. aegypti and the maintenance...

This study compared the effectiveness of the currently available interventions of dengue vector and dengue hemorrhagic fever (DHF) control used in northeastern Thailand, an area with a high incidence of the disease. Also, the basic knowledge of dengue vector and DHF control of a group of 568 participants from local communities was measured. These communities were divided into two groups that ha...

Mathematical models can be used to describe the transmission of disease. Dengue disease is the most significant mosquito-borne viral disease of human. It now a leading cause of childhood deaths and hospitalizations in many countries. Variations in environmental conditions, especially seasonal climatic parameters, effect to the transmission of dengue viruses the dengue viruses and their principa...
