Since June 2012 and up to 25 November 2012, a total of six confirmed cases of infection with the novel coronavirus (of whom two died) have been reported to WHO. All cases share a history of residence in, or travel to, the Kingdom of Saudi Arabia (KSA) or Qatar. The source and possible routes of transmission of the virus remain unknown.
ECDC updated risk assessment concludes that in the absence of evidence of sustained person-to-person transmission outside of household settings, the current facts still point towards a hypothesis of a zoonotic or environmental source with occasional transmission to exposed humans. WHO does not advise any travel or trade restrictions at this point for KSA or Qatar.
