Anti-malarial virus

American researchers have found a new virus that can infect Anopheles mosquitos which act as carriers of the parasite causing malaria. The idea is to use the virus to pass on genetic information that will kill the mosquito before it infects humans. Malaria is one of the leading causes of death in rural areas of asia and africa. Drugs are available to treat the disease but most of the people die because of lack of awareness. Prevention is always better than cure. The new virus AgDNV is a densovirus type and it can secrete a strong toxin inside the mosquito or ask the mosquito to die in 10 days. It was a fairy tale discovery while they were researching on Wolbachia bacteria. But there is a long way to go from here to implement the strategy for malaria control in real life.
