The Vietnam’s National Insitute in cooperation with Monash University in Melbourne Australia, plan to release around 1.4 million mosquitos carrying the bacterium Wolbachia to establish a stable population of the dengue-neutralizing insects. Wolbachia is an Endosymbiotic bacterium that shorts the lifespan of Aedes aegypti mosquitoes while partially or entirely blocking them from contracting the dengue virus.
This project will be carried out in March 2017, and Wolbachia-carrying mosquitos will be released in 4 wards in Nha Trang City including Vinh Phuoc, Vinh Tho Ward in the north of Nha Trang, Vinh Truong and Phuoc Long Ward in the south of Nha Trang.
The mosquitoes will be released gradually between 12 and 18 weeks, and are expected to multiply and make up at least 70 percent of the local Aedes aegypti mosquito count three months after the release.
In 2013, Wolbachia-infected Aedes aegypti mosquitoes were released in Tri Nguyen off the Nha Trang coast to test how they would grow and replace the endemic population. By the beginning of December 2014, over 90 percent of the mosquito population on Tri Nguyen Island had been replaced with the Wolbachia-carrying ones, according to the Eliminate Dengue Program.
Today Asia currently bears 70% of the world’s dengue burden. Last year, Vietnam recorded nearly 82,000 infections in total, including 52 deaths. Health officials note that today compared to the median in the 2010-2014 period, the cumulative number of Dengue cases increased by + than 125%.Dengue is a viral infection transmitted by the bite of an infected mosquito that brings Fever, rash, hemorrhage, loss of consciousness, respiratory failure abnormal liver, kidney and brain function and there is still there is no definite cure for the disease.
