Mobile Phones Could Help Efforts to End Malaria download Caroline Buckee is an assistant professor of epidemiology at the Harvard school. She says one of the first steps in stopping malaria is to learn how human travel might be adding to its spread. She says it has been difficult to follow large population movements with methods like government census records. In Kenya, the researchers estimated the distance and length of each phone user's trip away from home. This information was based on messages to and from the mobile phone carrier's twelve thousand transmission towers. The researchers then compared that information to a map showing reports of malaria in different parts of the country. The researchers estimated each user's probability of being infected in a given area. They also estimated the likelihood that a visitor to that area would become infected. The result was a picture showing malaria transmission routes starting in Lake Victoria. Caroline Buckee says such evidence could influence malaria control efforts. She says researchers are investigating using mobile phone records in other areas to help identify malaria transmission routes. A report on the study was published in the Journal Science.
