Mosquito Vector Control Dengue

Anopheles mosquitoes themselves are known to transmit a few viruses including Mayaro virus and Onyong nyong virus. Professionals from local health departments or mosquito control districts develop mosquito control plans perform tasks to control larvae and adult mosquitoes and evaluate the effectiveness of actions taken.

Pin On Dengue

The control of dengue depends solely on the suppression of the two most important vectors namely Aedes aegypti and Ae albopictus.

Mosquito vector control dengue. There is at present a lack of specific treatment and an effective tetravalent vaccine against dengue. You your neighbors and the community can also take steps to reduce mosquitoes in and. Infection with one type usually gives lifelong immunity to that type but only short-term immunity to the others.

Dengue is a mosquito-borne disease caused by any one of four closely related dengue viruses DENV-1 DENV-2 DENV-3 and DENV-4. Although several countries used vaccine against DENV in humans ranged between 9 and 45 years of age inhabiting in endemic areas but the mosquito control is still the main approach to stop the dengue disease. Dengue Vector Control Approaches to the prevention and control of dengue fever have relied on the control of the Ae.

It has turned into an endemic in Bangladesh and may strike anytime around the year. Aegypti mosquito is well adapted to mankind. Dengue is spread by several species of female mosquitoes of the Aedes genus principally Aedes aegypti.

The virus has five serotypes. Dengue is vector-borne disease. A look at the tools stopping the mosquitoes that spread dengue.

Preventing or reducing dengue virus transmission depends entirely in controlling the mosquito vectors or interruption of humanvector contact. The proximity of mosquito vector breeding sites to human habitation is a significant risk factor for dengue as well as for other diseases that Aedes mosquito transmit. 8 The primary vector of dengue Ae.

April 19 2017 – by KRIZETTE CHU. Dengue is common in more than 100 countries around the world. Dengue is a serious mosquito borne disease common in tropical and sub-tropical countries including Malaysia.

WHO promotes the strategic approach known as Integrated Vector Management IVM to control mosquito vectors including those of dengue. An element of IVM is decision-making guided by operational research and entomological and epidemiological surveillance and evaluation. Assessing risk of human infection base.

This aims to kill infected adult females within a radius of about 200 metres the distance a vector might fly. Subsequent infection with a different type increases the risk of severe complications. If the Aedes mosquito carrier of the dengue virus is not controlled then the disease may rise anytime.

But the most important viral vector is the mosquito Aedes aegypti which. Dengue viruses are spread to people through the bite of an infected Aedes species Ae. Tools and methodology of dengue vector surveillance is reviewed from time to time and starting from April 2020 a new tool gravidtrap has been adopted to replace ovitrap for monitoring the dengue vector of Aedine mosquitoes in selected areas.

As the mosquitoes have to breed in water it is more effective and efficient to control mosquito. Albopictus is a possible transmitter. In dengue receptive areas an outbreak prompts urgent and intensive mosquito control activities around the addresses where the cases may have been viraemic.

The use of multiple strategies for vector-borne disease prevention is the basis of WHOs Integrated Vector Management IVM program for control of mosquito vectors including those that transmit DENV 35. Vector control refers to actions used to control a vector in this case the mosquito which can transmit a pathogen the four dengue viruses. The Ovi-Trap System OTS with test solution was able to attract about 70 of Aedes Mosquito population as compared to 30 using OTS with plain water Oviposition response to different concentrations of aqueous solution showed three times better at 1000ppm and five times better at 2000ppm as compared to negative control.

Where does dengue occur. At present the main method to control or prevent the transmission of dengue virus is to combat the mosquito vectors. Accounting for variation in mosquito vector populations will improve dengue surveillance and prevention.

At a press briefing Monday the agency said 1303 cases of dengue have been reported so far this year including 394 cases from the capital Malé. MANILA PHILIPPINESAt last months second Asia Dengue Summit in Manila top infectious disease experts from the region met with government officials and public health stakeholders to discuss the increasing burden of dengue and the advances in science and technology. Aegypti is highly domestic and blood-feeds and harbours within premises.

Aegypti mosquito is the main vector of Dengue Zika chikungunya and yellow fever diseases also A. Because Aedes aegypti the principle dengue virus DENV vector transmit the virus with remarkable efficiency entomological thresholds are especially low. The Health Protection Agency has launched a vector control campaign after more than 1000 cases of mosquito-borne disease were reported across the country.

Forty percent of the worlds population about 3 billion people live in areas with a risk of dengue. So there is no alternative to controlling the vector he added. Dengue occurs in many tropical and sub-tropical areas of the world particularly sub-Saharan Africa the Middle East Southeast Asia and Central and South America.
