The World Health Organization says malaria mortality rates have fallen by 25% since 2000. Yet the disease killed an estimated 655,000 people in 2010.
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.
That is what Harvard University researchers discovered in Kenya. They found that the disease mainly spreads east from the country's Lake Victoria area with people who travel to the capital, Nairobi.
Researchers with the Harvard School of Public Health reported the finding. It was based on the mobile phone records of 15 million Kenyans.研究人员正在琢磨如何使用手机来记录疟疾的传播。这项研究是他们想要切断或控制该疾病传播所做的一部分努力。
世界卫生组织表示自2000年以来，疟疾的死亡率下降了25％。但2010年仍有大约65.5万人死于疟疾。
科学家们表示携带疟疾病毒的蚊子本身飞不远。但它们却可以躲藏在旅行者的随身物品中。疟疾也可通过来自疟疾高发地区的人传播。他们自身可能并没有患病迹象。
以上结论是哈佛大学的研究人员在肯尼亚的研究所得。他们发现疟疾主要是由去首都内罗毕旅行的人从该国维多利亚湖区向东部传播的。
哈佛公共卫生学院的研究人员报告了这一研究结论，该结论正是根据1500万肯尼亚人的手机记录所得的。
