Recent scholarship has focused on using social media (e.g., Twitter, Facebook) as a secondary data stream for disease event detection. However, reported implementations such as (4) underscore where the real value may lie in using social media for surveillance. We provide a framework to illuminate uses of social media beyond passive observation, and towards improving active responses to public health threats.
User-generated content enabled by social media tools provide a stream of data that augment surveillance data. Current use of social media data focuses on identification of disease events. However, once identification occurs, the leveraging of social media in monitoring disease events remains unclear (2, 3). To clarify this, we constructed a framework mapped to the surveillance cycle, to understand how social media can improve public health actions.
This framework builds on extant literature on surveillance and social media found in PubMed, Science Direct, and Web of Science, using keywords: “public health”, “surveillance”, “outbreak”, and “social media”. We excluded articles on online tools that were not interactive e.g., aggregated web-search results. Of 2,064 articles, 23 articles were specifically on the use of social media in surveillance work. Our review yielded five categories of social media use within the surveillance cycle (Table 1). This framing within surveillance illuminates a range of roles for social media tools beyond disease event detection. [Insert Image #1 here]
We used this “pre-social media” disease event to underscore where the real value of social media may lie in the surveillance cycle. Thus for 1918, early detection of disease could have occurred with many, e.g., sailors aboard ships in New York City’s port sharing their “status updates” with the world. [Insert Image #2 here]
The interactivity of social media moves us beyond using these tools solely as uni-directional, mass-broadcast channels. Beyond messaging about disease events, these tools can simultaneously help inform, connect, and intervene because of the user-generated feedback. These tools enable richer use beyond a noisy data stream for detection.
