The World Health Organisation (WHO) has confirmed two more fatal cases of a respiratory virus in the Middle East, the Associated Press has reported. The two coronavirus cases date back to April and are part of a cluster of a dozen people, mostly health workers, who fell sick in an intensive care unit at a hospital in Zarqa, Jordan. The new virus has so far been identified in patients from Saudi Arabia and Qatar. Scientists haven't found any links between the sporadic cases of the coronavirus so far, first detected in September. "We don't know how the virus gets around and there are more questions than answers right now," said WHO spokesman Gregory Hartl.
