Competing Interests

Drs. Brownstein and Freifeld report being co-creators of the HealthMap system and hold an equity stake in, and are consultants to Epidemico, a spinoff company of Boston Children’s Hospital that handles licensing of HealthMap data. Dr. Mekaru declares no conflicts of interest. Drs. Ahmed, Oviedo-Orta, and Tougas are employees of Novartis and hold stock in Novartis AG. This does not alter the authors' adherence to PLOS ONE policies on sharing data and materials.
