An analysis of Twitter hashtag use on the subject of diabetes provides new insights about spreading health information through social media. The study, led by Jenine Harris, PhD, assistant professor at the Brown School at Washington University in St. Louis, looked at the hashtag #diabetes and its interaction with two Twitter measures of engagement, retweeting and favoriting. The study found retweeting and favoriting was significantly lower for tweets about the number or percentage of people with diabetes, while favoriting was higher for tweets about health problems associated with diabetes.

An estimated 55 million to 105 million people in the United States suffer from foodborne illnesses each year, resulting in costs of $2-$4 billion annually. What if Twitter could be used to track those cases and more quickly identify the source of the problem? A new analysis by a researcher at Washington University in St. Louis Brown School shows that new technology might better allow health departments to engage with the public to improve foodborne illness surveillance.
