New discovery: Malaria blocking mosquitoes !

What is Malaria?

            Malaria is a mosquito-borne infectious disease of humans and other animals caused by parasitic protozoans (a group of single-celled microorganisms) belonging to the Plasmodium type.Malaria causes symptoms that typically include fever, fatigue, vomiting, and headaches. In severe cases it can cause yellow skin, seizures, coma, or death.Symptoms usually begin ten to fifteen days after being bitten. If not properly treated, people may have recurrences of the disease months later. In those who have recently survived an infection, reinfection usually causes milder symptoms. This partial resistance disappears over months to years if the person has no continuing exposure to malaria.


            The disease is most commonly transmitted by an infected female Anopheles mosquito. The mosquito bite introduces the parasites from the mosquito's saliva into a person's blood.The risk of disease can be reduced by preventing mosquito bites by using mosquito nets and insect repellents, or with mosquito-control measures such as spraying insecticides and draining standing water.

New Discovery:
                 “Prevention is better than cure.”

As said above, scientists are trying to prevent the spread of disease from one to another through mosquitoes. They found a gene which will stop the transmission of malaria through 99.5% of their offspring. They introduced this malaria-blocking genes into the mosquitoes and found good results. They use this mosquitoes to solve the purpose. The genes from this mosquitoes will pass to other mosquitoes through progeny which will totally eliminate the total transmission of disease to human beings.
