BALTIMORE — "Too sick to go to work, but not sick enough not to tweet about it" Twitter users are helping to predict flu trends. Johns Hopkins researchers recently created a Twitter search method that helps differentiate between people merely tweeting about the flu in general and those who are actually sick, the university announced Thursday. The new tweet-screening method not only delivers real-time data on flu cases, but also filters out online chatter that is not linked to actual flu infections.
