But experts know the new nets are a limited solution, as they expect mosquitos to eventually become resistant to the second-generation bed nets. Research on other means of vector control continues to be necessary, said Wagman, as is vaccinating a larger percentage of the population against the disease.

The rollout of malaria nets sprayed with a new, highly potent insecticide has prevented at least 13 million cases of the disease in Africa, a recent study has shown.

An innovative, cost-effective mosquito net has prevented 13 million malaria cases and 25,000 deaths in countries of sub-Saharan Africa.

A new kind of mosquito net delivered across sub-Saharan Africa averted an estimated 13 million malaria cases and nearly 25,000 deaths over three years, the project's backers said Wednesday.
