Mosquito Sting:A Host of Parasites and Virions

Mosquitoes are a vector agent that carries mosquito-borne disease, transmitting viruses and parasites from person to person without catching the disease themselves. Mosquitoes carrying these viruses stay healthy while carrying them because their immune system recognizes them as bad and "chops off" the virus's genetic coding, rendering it harmless. It is currently unknown how they handle parasites so they can safely carry them. Infection of humans occurs when a mosquito bites someone while its immune system is still in the process of destroying the virus's harmful coding. Female mosquitoes suck blood from people and other animals as part of their eating and breeding habits. Mosquito borne diseases are prevalent in more than 100 countries, infecting 300-500 million people and causing about 1 million deaths every year. In India, more than 40 million people suffer from mosquito diseases annually. There are a number of diseases borne by mosquitoes. They are malaria, filaria, dengue, brain fever and yellow fever. Yellow fever is caused by mosquitoes in jungle areas in parts of Africa and South America. In India, malaria, filaria and dengue are the most prevalent diseases spread by mosquitoes. The diseases continue to explode from time to time. The reason is that these mosquitoes develop resistance to medicines and chemicals. Hence fighting mosquitoes and the diseases spread by them is a continuous process.
