The change in the epidemiology of MERS-CoV over the past weeks is of concern as stated in a facebook post by WHO’s Eastern Mediterranean Regional Office on 23 April 2014 [11]. Interestingly, over the past two years, voices on social media have been increasingly important for reports about the MERS-CoV situation as they have kept the topic high on the agenda of by raising pertinent questions, curating content on blogs, and reporting on cases in near-real time via Twitter. We have seen the MERS CoV debate on Twitter engage bloggers and journalists along with public health organisations, epidemiologists and doctors alike, often resulting in faster reporting and better understanding of the situation. This debate relates to a new phenomenon called ‘crowd epidemic intelligence’ [12] and is particularly important given the many unknowns about the MERS epidemic.
