Dr. Ian Mackay's Virology Down Under blog emerged into Flublogia this spring almost as quickly as H7N9 and MERS did. He has a new post on his Middle East Respiratory Syndrome Coronavirus (MERS-CoV) page:
Quick (sometimes rough) numbers
As of 17th June; FluTrackers, CIDRAP, WHO
• Total human cases of MERS-CoV: 64a
• Total deaths attributed to infection with MERS-CoV: 36
• Current Case Fatality Rate (CFRd): 56%
a Data from FluTrackers, WHO and the European CDC.
b This uses numbers based on publicly available data which may lack detail. This number gives you an idea of our understanding at the moment. To be pedantic and use only the number of discharges as the denominator for the CFR is most useful at the end of an outbreak/epidemic/pandemic, but not so much when data-in-hand is poor during the beginning.
