Digital Public Health Surveillance

Social Media Analysis

Digital Public Health Surveillance

Digital platforms such as social media and search engines effectively capture people’s online activities. Because online users freely share their activities and opinions about a variety of topics related to health, such digital data can support novel public health surveillance. Compared to traditional surveillance systems based on surveys or case reporting, digital data enable real-time surveillance with much greater temporal and spatial resolution. In this research area, we have utilized Twitter, Google Trends, and Yelp to investigate various surveillance opportunities. In particular, we are using large-scale Twitter data and machine learning to monitor physical activity, sedentary behaviour, and sleep quality at the population level.
