WHO MERS Saudi Arabia Update - 5 Hofuf Cases











# 10,160



We've been following a sizable cluster of MERS cases emerging from the city of Hofuf (aka `Hafuf', `hafoof', etc.) for almost 7 weeks.   The first case - reported on April 20th - involved a case with camel contact (see here).

A second case – described as `a contact’ of the first was reported on May 5th.  Two days later 4 more cases described as `household contacts of a confirmed case’ were reported.

Since then we've seen a steady procession of cases - most listed as `contacts' of a previously identified case. In recent days we've seen WHO updates indicating that many of these were either healthcare workers (HCWs), or patients staying in same hospital where MERS cases were being treated (see June 4th's WHO MERS Update - Saudi Arabia ). 


Today's update differs in that two of the five cases listed  (#1 & #3) appear to be community acquired cases, with no stated links to previously identified cases, while #4 is an HCW with no known risk exposures.

Case #2 is an HCW who provided care to a lab-confirmed MERS case, while #5 was hospitalized for an unrelated illness and developed symptoms 11 days later.
