Social Media for Population Health Surveillance

Social media represent a big part of many people’s online activities. Because social media users freely share their activities and opinions about a variety of topics including health, social media data can be leveraged for population health surveillance. Compared to traditional surveillance systems that are usually based on surveys or case reporting, social media enable real-time surveillance with much greater temporal and spatial resolution. In particular, we have utilized Twitter and Google Trends data to build a surveillance system for monitoring physical activity, sedentary behaviour, and sleep at the population level.
