WHO MERS Update - Saudi Arabia











# 11,156


For the second time this week the WHO has published a Saudi Arabian MERS update.  Today's report is a mixed bag, with 7 cases, four of which stem from the ongoing Buraidah outbreak.

  • Two cases had a history of frequent contact with dromedaries and consumption of their raw milk.
  • One case is a health care worker in the hospital where the MERS-CoV outbreak is occurring
  • Three cases were patients  admitted to the hospital where the MERS-CoV outbreak is occurring.
  • One patient is a community acquired case with no known risk exposure.
 
Monday's report on 25 cases (see WHO MERS Update - Saudi Arabia) contained 12 cases from the Buraidah hospital cluster, 6 cases with camel exposure, 5 primary cases without a known exposure, and 2 contacts of previously identified MERS cases.


While preventing camel-to-human transmission and halting the nosocomial transmission of the virus in health care facilities are high priorities, for a substantial number of MERS cases their source of infection remains a mystery.
