Daily zero-reporting for suspect Ebola using short message service (SMS) in Guinea-Bissau

Real-time, SMS-based, daily zero-reporting can be implemented in a rapid, simple way in a low resource country. We believe that the high compliance rates were due to the simplicity and familiarity of SMS and heightened sensitivity that resulted from STEP to the importance of zero-reporting in the midst of an Ebola epidemic in neighbouring countries. This model could be useful for rapid scale-up and implementation of alert systems in other outbreaks and public health emergencies.
