Researchers are studying the use of mobile phones to document the spread of malaria. The study is part of an effort to stop or control the disease.

?

The World Health Organization says malaria mortality rates have fallen by twenty-five percent since two thousand. Yet the disease killed an estimated six hundred fifty-five thousand people in twenty-ten.

?

Scientists say malaria-carrying mosquitoes cannot travel far on their own. But the insects can, and do, catch rides in the belongings of people who travel. Malaria also can be spread by people who come from an area with large numbers of malaria cases. They may show no signs of having the disease themselves.
