Web Surveillance Predicts Disease Outbreak

January 17, 2014
(Medical Xpress)—The habit of Googling for a web-based analysis earlier than visiting a GP can present early warning of an infectious illness epidemic.
In a new research revealed in Lancet Infectious Ailments, internet-based mostly surveillance has been discovered to detect infectious illnesses such Dengue Fever and Influenza as much as two weeks sooner than conventional surveillance methods.
Senior creator of the paper titled Internet-primarily based surveillance systems for monitoring emerging infectious ailments, QUT Senior Research Fellow Dr Wenbiao Hu mentioned when investigating the prevalence of epidemics, spikes in searches for details about infectious illnesses might accurately predict outbreaks of that disease.
Dr Hu, based at QUT's Institute for Health and Biomedical Innovation, said there was often a lag time of two weeks earlier than conventional surveillance methods could detect an rising infectious disease.
"This is because traditional surveillance relies on the patient recognising the signs and looking for treatment before diagnosis, along with the time taken for health professionals to alert authorities by means of their well being networks," Dr Hu mentioned.
"In contrast, digital surveillance can present real-time detection of epidemics."
Dr Hu said the research discovered by utilizing digital surveillance through search engine algorithms similar to Google Traits and Google Insights, detecting the 2005-06 avian influenza outbreak "Chicken Flu" would have been attainable between one and two weeks earlier than official surveillance reports.
"In one other example, a digital data collection community was discovered to have the ability to detect the SARS outbreak more than two months before the primary publications by the World Health Organisation (WHO)," he said.
"Early detection means early warning and that can help cut back or contain an epidemic, as properly alert public health authorities to make sure risk administration methods corresponding to the provision of adequate medicine are applied."
Dr Hu mentioned the examine found social media and micoblogs together with Twitter and Facebook is also effective in detecting illness outbreaks.
"There is the potential for digital expertise to revolutionise emerging infectious illness surveillance," he stated.
"While this examine has seemed at the effectiveness of digital surveillance techniques retrospectively, Australia is well-placed to take the lead in developing an actual-time infectious disease warning surveillance system.
"The following step can be to mix the approaches presently accessible equivalent to social media, aggregator websites and search engines like google and yahoo, together with other elements corresponding to local weather and temperature, and develop an actual-time infectious illness predictor."
He mentioned it was also vital for future analysis to explore ways to apply internet-based surveillance methods on a global scale.
"The worldwide nature of rising infectious illnesses combined with the globalisation of journey and trade, have elevated the interconnectedness of all international locations and means detecting, monitoring and controlling these diseases is a global concern."
