Data Mining Google May Help Predict Disease OutbreaksEmerging research suggests mining Google queries could give public health officials a heads-up on emerging infectious disease outbreaks.

In a new study published in Lancet Infectious Diseases, Internet-based surveillance has been found to detect infectious diseases such dengue fever and influenza up to two weeks earlier than traditional surveillance methods.

Wenbiao Hu, Ph.D., an Australian researcher and senior author of the paper, believes the new method is valuable as traditional surveillance methods often experience a lag before they detect an emerging infectious disease.

“This is because traditional surveillance relies on the patient recognizing the symptoms and seeking treatment before diagnosis, along with the time taken for health professionals to alert authorities through their health networks,” Hu said.

“In contrast, digital surveillance can provide real-time detection of epidemics.”

Hu said the study found by using digital surveillance through search engine algorithms such as Google Trends and Google Insights, detecting the 2005-06 avian influenza outbreak “bird flu” would have been possible between one and two weeks earlier than official surveillance reports.

“In another example, a digital data collection network was found to be able to detect the SARS outbreak more than two months before the first publications by the World Health Organization (WHO),” he said.

“Early detection means early warning and that can help reduce or contain an epidemic, as well alert public health authorities to ensure risk management strategies such as the provision of adequate medication are implemented.”

Hu said the study found social media and micoblogs including Twitter and Facebook could also be effective in detecting disease outbreaks.

“There is the potential for digital technology to revolutionize emerging infectious disease surveillance,” he said. “While this study has looked at the effectiveness of digital surveillance systems retrospectively, Australia is well-placed to take the lead in developing a real-time infectious disease warning surveillance system.

“The next step would be to combine the approaches currently available such as social media, aggregator websites and search engines, along with other factors such as climate and temperature, and develop a real-time infectious disease predictor.”

He said it was also important for future research to explore ways to apply Internet-based surveillance systems on a global scale.

“The international nature of emerging infectious diseases combined with the globalization of travel and trade have increased the interconnectedness of all countries and means detecting, monitoring and controlling these diseases is a global concern.”
