The World Health Organization has released two MERS updates, although for reasons that are not explained, the 11 cases cited in the March 25th report are repeated among the 15 cases reported in today’s report.

 

Disease Outbreak News (DONs)

Recent DONs
  • 26 March 2015
    Middle East respiratory syndrome coronavirus (MERS-CoV) – Saudi Arabia
  • 25 March 2015
    Middle East respiratory syndrome coronavirus (MERS-CoV) – Saudi Arabia

 

As we’ve seen previously, the probable source of exposure to the virus isn’t known for many of these cases. Of the 15 listed today:

  • 6 have no known risk exposures listed.
  • 4 have possible hospital exposures, but only 1 (HCW) of those is a known contact of an infected patient. 
  • Three have frequent animal contact; 2 with camels and 1 with sheep.  
  • And two are listed as (community) contacts of known cases

 

As we’ve discussed previously (see The Community Transmission Mystery), while the source of some MERS infections are fairly obvious, for the vast majority we still don’t know how these patients were exposed.
