WHO MERS Update – Saudi Arabia July 3rd

Saudi Region

 

# 10,296

 

The World Health Organization has published a DON update describing 6 recent MERS cases in Saudi Arabia;  two from Riyadh and four linked to the ongoing outbreak in Hofuf which started in mid-April.

 

No known risk exposures are listed for the two Riyadh cases, highlighting the fact that the source of many community-acquired infections remains elusive.   As we discussed yesterday, there remain major gaps in our understanding of how this virus is spreading – particularly outside of the hospital environment.


The four Hofuf cases involve a HCW at a facility where MERS cases are being treated, the relative of an infected HCW, and two patients who appear to have contracted the virus while hospitalized in facilities treating MERS cases.

 

The Hofuf cluster – which now runs roughly 40 cases – has shown signs of slowing with no new cases reported from Hofuf in more than a week, and only 1 case reported from nearby Dammam two days ago. It is  unknown whether the Dammam case is related to the Hofuf cluster.
