Promoting Dengue Vector Surveillance And Control

Forty percent of the worlds population about 3 billion people live in areas with a risk of dengue.

Distribution of dengue vector mosquitoes. Dengue is common in more than 100 countries around the world. Temporal and Spatial Distribution of Dengue Vector Mosquitoes and their Habitat Patterns in Penang Island Malaysia March 2013 Journal of the American Mosquito Control Association 29133-43. The majority of the Yucat an State Mé xico presents subtropical climate that is suitable for many species of mosquitoes that are known to be vectors of diseases including those from the genera Aedes and Culex.

The mosquito Aedes aegypti Diptera. Hence in the present study the mosquito larval survey was performed in container water in Tiruchirappalli district to investigate the distribution dynamics of dengue vector. Materials and methods 21 Study Area The mosquito larval survey was conducted from September 2012 to March 2013 in Turaiyur.

Mosquitoes are small two-winged insects up to 15 mm in size. Historically it is the spread of Aedes mosquitoes that has driven expansion of dengue. Dengue virus is transmitted by female mosquitoes mainly of the species Aedes aegypti and to a lesser extent Ae.

Colombo and Kandy districts were the first 718 dengue cases and third 940 dengue cases high-risk districts of the country in 2019 respectively. Mosquitoes belong to the insect order Diptera suborder Nematocera. The geographical distribution of Dengue and Chikungunya vector mosquitoes Aedes aegypti and Aedes albopictus and vector density are spatially associated with the areas where it receives the monsoon rainfall 500mm-1000 mm and followed by moderately associated with rainfall 1000mm-3000 mm Map source.

Dengue viruses are spread to people through the bite of an infected Aedes species Ae. Dengue viruses circulate mainly between human and vector mosquitoes and the vector presence is a limiting factor of transmission. The dengue virus is naturally transmitted by Aedes mosquitoes between humans or monkeys in the jungle cycle.

Dengue is often a leading cause of illness in areas with risk. Dengue DEN is a vector-borne disease in humans as a major public health concern in many tropical and subtropical countries 1It is the most rapidly spreading mosquito-borne viral disease that. Vertical transmission of dengue virus types 2 3 and 4 has been demonstrated 25 and although some suggest this is inefficient 45 others suggest that it plays a significant role in viral maintenance.

Its role in both. Dengue is a systemic viral infection transmitted between humans by Aedes mosquitoes. For some patients dengue is a life-threatening illness.

Culicidae is the primary vector of dengue in Mexi co and lately virus Chikungunya although Aedes albopictus is widely distributed. Ecological Niche Model for Predicting Distribution of Disease-Vector Mosquitoes in Yucat an. Saifur Ahmad Abu Hassan Hamady Dieng Md Rawi Che Salmah Ahmad Ramli Saad and Tomomitsu Satho Temporal and Spatial Distribution of Dengue Vector Mosquitoes and their Habitat Patterns in Penang Island Malaysia Journal of the American Mosquito Control Association 291 33-43 1 March 2013.

Most existing global dengue projections anticipate widespread transmission in Europe inconsistent with the. DENV is transmitted through a humanmosquitohuman cycle throughout the tropical and subtropical regions of the world with Aedes aegypti as the primary vector 1. Five MOH areas that reported the highest number of dengue cases during the period of 20132019 were selected from each district.

Within this suborder the family Culicidae includes mosquitoes in some 110 genera and subgenera and about 3600 species with the most important genera Anopheles Culex Aedes and Mansonia. Transovarial or vertical transmission in mosquitoes themselves may also occasionally occur. The National Capital Region NCR of the Philippines or Metropolitan Manila is a highly urbanized area that is greatly affected by this arboviral disease.

The objective of this study is to. Therefore spatial distribution of dengue vectors is a significant concern in the epidemiology of the disease. There are currently no licensed vaccines or specific therapeutics and substantial vector control efforts have not stopped its rapid emergence and global spread.

Urbanization has been shown to increase the dispersal of this mosquito vector. AlbopictusThese mosquitoes are also vectors of chikungunya yellow fever and Zika viruses. Dengue is a highly endemic disease in Southeast Asia and is transmitted primarily by the mosquito Aedes aegypti.

Dengue is a mosquito-borne viral disease that has rapidly spread in all regions of WHO in recent years. To the environment around houses is related to different spatial distribution indoors and outdoors. All four dengue serotypes have been isolated from field-collected Ae.

Aedes aegypti is the primary vector of dengue 44.
