The roadside vendor shows the effective way to keep mosquitos away.

What a shame that millions are afflicted by malaria when all that is required is the use of a mosquito net to keep the bloody insects at bay.  Nobody has taught or had to teach this roadside vendor this elementary message.

Mosquito mats and other creams have been found to be harmful in the long term.  And a recent study found that the mosquito repellants are no longer effective.  

WHO has been spending millions of dollars for providing inseticide impregnated nets mainly in Africa.  And it has been shown that when used properly and every day, it can drastically cut the number of malaria cases.
