Via sabq.org: detained 300 passengers at Kuwait airport to infect someone with "Corona". The Google translation:
Follow-up: the Kuwaiti newspaper Al-Rai said via the social networking site "Twitter" It was the detention of 300 passengers at the airport in Kuwait, including Kuwaitis, interned in the Dutch airliner coming from Britain because of injury Dutch passenger virus "Corona."
The Kuwaiti newspaper did not explain more details about the incident.
I checked the website of Al-Rai; it has a story about the local health ministry gearing up to fight MERS, but nothing about this flight.
