Dengue/ Dengue Hemorrhagic fever (DF/DHF) is a mosquito borne-viral disease which affects millions in many tropical and subtropical areas of the world. In India, the disease is spreading rapidly to newer areas, with outbreaks occurring more frequently and explosively. Several studies have demonstrated natural vertical transmission of dengue virus by vector mosquitoes in which the virus is trans...

Vector-borne diseases impose enormous health and economic burdens and additional methods to control vector populations are clearly needed. The Sterile Insect Technique (SIT) has been successful against agricultural pests, but is not in large-scale use for suppressing or eliminating mosquito populations. Genetic RIDL technology (Release of Insects carrying a Dominant Lethal) is a proposed modifi...

Dengue infection, one of the most devastating mosquito-borne viral diseases in humans, is now a significant problem in several tropical countries. The disease, caused by the four dengue virus serotypes, ranges from asymptomatic infection to undifferentiated fever, dengue fever (DF), and severe dengue hemorrhagic fever (DHF) with or without shock. DHF is characterized by fever, bleeding diathesi...

Dengue virus (DENV) transmission risk is influenced by the bionomic traits of key vector, Aedes aegypti . We investigated patterns abundance, survival, and human blood-feeding Ae. populations in two environments Kenya: peri-urban Rabai (coastal Region, dengue-endemic) rural Kerio Valley (Rift no reported dengue outbreak). In both environments, survival (estimated parity), was inversely correlat...

Dengue has become a major public health problem worldwide. Ae. albopictus, vector responsible for transmission, was first detected in Catalonia in 2004. Since then, it has established along Mediterranean coast. The aim of this paper is to describe the risk of importation and possible autochthonous transmission of dengue virus in Spain, qualitatively reviewing factors that could influence the em...

BACKGROUND/OBJECTIVES Understanding the factors underlying the spatio-temporal distribution of infectious diseases provides useful information regarding their prevention and control. Dengue fever spatio-temporal patterns result from complex interactions between the virus, the host, and the vector. These interactions can be influenced by environmental conditions. Our objectives were to analyse d...

Dengue fever is increasing in geographical range, spread by invasion of its vector mosquitoes. The trade in second-hand tires has been implicated as a factor in this process because they act as mobile reservoirs of mosquito eggs and larvae. Regional transportation of tires can create linkages between rural areas with dengue and disease-free urban areas, potentially giving rise to outbreaks even...
