WHO MERS-CoV Update - Saudi Arabia: Feb 29th

Credit WHO












# 11,078


After a couple of slow months Saudi Arabia has seen an uptick in MERS cases this month, with 20 cases reported during February.  Today the World Health Organization updates us on the first 6 cases of the month, 3 of which were fatal.

Of these cases, two appear to have had camel contact, three have no known risk exposures, and one is a contact of a laboratory confirmed MERS case (#6 below).

Since the cut off date (Feb 16th) for this report we've seen 14 new cases, including three cases that appear to be linked from Riyadh.  We'll have to wait for the next WHO update to learn if any of those three are linked to the two cases (#4 & #6)  in today's report.

Globally, since September 2012, WHO has been notified of 1,644 laboratory-confirmed cases of infection with MERS-CoV, including at least 590 related deaths.

WHO risk assessment

MERS-CoV causes severe human infections resulting in high mortality and has demonstrated the ability to transmit between humans. So far, the observed human-to-human transmission has occurred mainly in health care settings.
 
The notification of additional cases does not change the overall risk assessment. WHO expects that additional cases of MERS-CoV infection will be reported from the Middle East, and that cases will continue to be exported to other countries by individuals who might acquire the infection after exposure to animals or animal products (for example, following contact with dromedaries) or human source (for example, in a health care setting). WHO continues to monitor the epidemiological situation and conducts risk assessment based on the latest available information.
