Happy 2nd birthday Middle East respiratory syndrome coronavirus (MERS-CoV)...

Its been 2-years since Prof. Ali Mohamed Zaki sent his email to ProMED notifying them of a novel coronavirus. That email was published 20-Sept 2012.[1] 

A year ago we had 138 cases and 58 deaths. Today we have 856 cases with perhaps 306 fatal (36%).

I won't rehash what I said a year ago - I invite you to check that out over at the 1st birthday post.[2]

Suffice to say the past year has been, to my mind anyway, mostly about:

  • Camels
  • High level job "shuffling"
  • Controversial parallel publications
  • Very problematic infection prevention and control issues.
The latter leading to the relatively huge number of MERS-CoV detections and deaths in Saudi Arabia and to some exported detections and cases. The one constant over both years has been that the MERS-CoV is a pitiful spreader among humans. MERS-CoV is nonetheless a virus that is very capable of inducing fatal outcomes, especially among older males with underlying diseases.

Has MERS-CoV gone away? No. Of course it hasn't. MERS has, mostly. That's the disease, not the virus. For now anyway MERS cases are sporadic, although still geographically widespread. 

MERS cases fell to zero cases per week for a number of weeks this year following containment of the Jeddah-2014 outbreak. Nonetheless, this is a virus of camels that seems to  spread, rarely, to humans and when in us, it has not been in any rush to mutate into the pandemic SARS-like threat many once worried about. 

Camels are where this virus likely remains. And there have been no signs that that has in any way changed. The latest information suggests camels have been harbouring MERS-CoV for at least 30-years.[3] This, as with a great deal of the research to date, is knowledge gained mostly thanks to the efforts of international research teams and their funding

So Happy 2nd Birthday you opportunistic, spiky little killer. I'm once again wishing Dr Zaki well and congratulating him on co-parenting the birth of this novel coronavirus. This year I also wish Prof. Ziad Memish well and congratulate him on seeing the infant virus through to toddler age.

Oh, and 2-years on, I still see no sign that the contentious patenting issues were any sort of hindrance to diagnostics or actual research. Just sayin'.
