Eckert, S., Sopory, P., Day, A., et al. (2017). Health-Related Disaster Communication and Social Media: Mixed-Method Systematic Review. (Abstract only.) Health Communication.
The authors reviewed literature on disasters across the globe from 2003-2016 to determine the best social media practices that could encourage health protection and dispel rumors. They emphasized that governmental agencies should use social media (especially Twitter and Facebook) daily and during emergencies. They also noted a dearth of research pertaining to who is reached by social media versus who needs to be reached by other communication channels.
