Behaviour analysis app could help to limit spread of disease

Localised epidemics and global pandemics periodically pose a significant national and global threat. When this happens, it becomes vital for public health and government authorities to track how far and how fast the disease is spreading.

However, to minimise the health, social and economic impact as much as possible, it is also important to know how people are likely to change their behaviour during the course of an epidemic.

According to Jon Crowcroft, the Marconi professor of communications systems in the Computer Laboratory at Cambridge University, understanding how people behave might help authorities to devise strategies to reduce the scale or length of the crisis and to tailor healthcare messages effectively.

The Cambridge FluPhone app in the mobile phone works by monitoring influenza-like symptoms by prompting questions for the mobile phone owner. It also captures physical proximity information between individuals by recording other devices nearby via Bluetooth communication.

In a pilot study of the app, volunteers were asked to download the application to their mobile phones. Data collected over a few months — which happened to coincide with an outbreak of swine flu — demonstrated the potential of using mobile phones to measure the social activity of the population in real time, providing data that would be otherwise unavailable.
