The dengue fever as imported epidemics disease spread in China, scientist control and fight it from spreading.
Dengue fever is a noticeable disease in China, a worst outbreak recorded last year with thousands of cases. This is a mosquito-borne tropical disease caused by the dengue virus with symptoms of fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles.
It has spread everywhere, and infected thousands of people. A life-threatening in people with diabetes and asthma, and lower platelets in the blood. Dengue has become a global problem, occasionally affect several other body systems.
The country put up world’s largest mosquito factory, Guangzhou province. This is to control spreading of dengue fever, scientist managed by releasing millions of produced and sterilized mosquitoes to combat dengue fever. Aside from working to get rid of mosquito carrying disease, they were also working on dengue vaccine and some possible medication to the virus.
Xi Zhiyong, a microbiology professor at Sun Yat-sen University and a member of the research team behind the project stated, “We are continuing research work so that every step of the process can be better controlled and measured”, “Dengue viruses normally need to replicate in mosquitoes. But the symbiotic bacteria can prevent the replication of the viruses. So the viruses are controlled in the mosquitoes.”
The specially bred mosquitoes infected with wolbachia bacteria. It makes the males sterile and limit the insects’ ability to carry dengue. Xi Zhiyong releases mosquitoes that do not carry dengue, targeting insects with the disease. Through releasing specially-bred mosquitoes, high percentage of dengue-carrying mosquitoes expected to be eliminated in some parts of Guangzhou.
According to the report, mosquito “factory” was opened on July 17 and is able to produce millions of male mosquitoes every week that infected with wolbachia, a bacteria that exists widely in many insects, including mosquitoes.
As of now, there is no commercially available vaccine. However, range of the disease appears to be expanding possibly due to climate change. Prevention depends on control and protection from the bites of the mosquito that transmits dengue fever. IMAGE/www.udayavani.com
