Mobile Phone Records May Predict Epidemics of Mosquito-Borne Dengue Virus
Tuesday, September 8, 2015
A new study led by researchers at Harvard T.H. Chan School of Public Health finds that mobile phone records can be used to predict the geographical spread and timing of dengue epidemics. More people around the world are becoming vulnerable to this deadly virus as climate change expands the range of the mosquito that transmits dengue and infected travelers spread the disease across borders. Utilizing the largest data set of mobile phone records ever analyzed to estimate human mobility, the researchers developed an innovative model that can predict epidemics and provide critical early warning to policy makers.
The study appears online September 7, 2015 in PNAS.
Dengue is the most rapidly spreading mosquito-borne disease worldwide. Infection can lead to sudden high fever, bleeding, and shock, and causes significant mortality.
The researchers analyzed data from a large dengue outbreak in Pakistan in 2013 and compared it to a transmission model they developed based on climate information and mobility data gleaned from call records. Data from nearly 40 million mobile phone subscribers was processed in collaboration with Telenor Research and Telenor Pakistan, with the call records being aggregated and anonymized before analysis.
