Efforts to prevent many life threatening diseases spreading by mosquitoes…

Increasing the immunity in mosquitoes shown a hope to prevent many diseases from the biting of mosquitoes. Scientists are trying to prevent diseases like Zika, Dengue, Malaria, Chikungunya, etc. that are spreading through mosquito biting. It is observed that by giving sugar to mosquitoes, the virus will not be able to infect them and diseases will not spread. The incidence of diseases like Zika and Dengue can be reduced by developing anti-viral immunity in mosquitoes. 

In their new experiment, scientists have developed immunity against the virus that spreads these diseases in mosquitoes. Scientists from Switzerland's MRC University of Glasgow Center for Virus Research, who studied, say that after feeding sugar to female Aedes aegypti mosquito that spreads diseases, the virus is not able to spread its infection in them. In this way, they are not able to transmit the virus to humans, and the risk of diseases decreases. 

Why do mosquitoes spread diseases like dengue? Mosquitoes depend on flower nectar for their energy, but they need blood for reproduction. To get this blood, they bite humans. During this time, the virus of diseases like Zika and Dengue present in them reaches humans. Researcher Dr. Emily Pondeville observed, after eating sugar, immunity against the virus increases in mosquitoes, but the reason why this happens is still not clear. However, this can reduce the cases of mosquito-borne diseases worldwide.

How deadly are mosquitoes proving to be? According to the World Mosquito Program, 700 million people worldwide get sick every year from mosquito bites. Of these, 10 lakh people die. Cases of Zika, Yellow Fever, Chikungunya, Malaria, and Dengue are reported in the maximum number of patients. According to the European Center for Disease Control Prevention, the number of yellow fever mosquitoes has increased so much in the last 20 to 30 years that they have become among the most disease-carrying mosquitoes. 

Dengue cases increased 30 times in 50 years- According to the World Health Organization (WHO), the dengue virus infects approx. 400 million people every year and about 25 thousand people die from it. According to the WHO, dengue cases have increased by 30 times in the last 50 years. Dengue virus causes fever and body aches after infection.
