WHO GAR Update On MERS – Saudi Arabia

Saudi Arabia

 


# 9395

 

We’ve a long, fairly detailed listing of 16 MERS cases reported by Saudi Arabia during the month of November courtesy of the World Health Organization’s GAR (Global Alert & Response) website. While these cases had previously been announced by the Saudi MOH, this WHO update provides additional details.


Although camel exposure and likely nosocomial transmission are mentioned in a number of these infections, for more than half of these cases the likely route of exposure is less than clear. 

 

The MERS coronavirus can produce a wide spectrum of disease in humans. Among diagnosed cases - roughly 50% are severe or life threatening while roughly 20% are described as being mild or asymptomatic.

 

The question of transmission from `asymptomatic’  carriers of the MERS virus, however, has yet to be resolved.

 

Last year we saw a  Study: Possible Transmission From Asymptomatic MERS-CoV Case suggesting it may be possible, and today’s report mentions at least two possible asymptomatic `bridges’ between potential cases (a nurse and a housekeeper) and newly infected individuals.  

 

But there remain sizable gaps in our understanding of the ecology and spread of the MERS virus. Answers that might be determined by a well-mounted case control study (see KSA Announces Start To Long-Awaited MERS Case Control Study), but which has yet to be published.
