Four Abu Dhabi doctors treating a man infected with Mers have also been infected with the coronavirus.
The healthcare workers from two hospitals were involved in treating an Emirati man, 82, who this month became the first in the UAE to contract the virus.
The Health Authority Abu Dhabi said the four, all in stable conditions, had been isolated.
The World Health Organisation said that of the four, a man, 28, and a woman, 30, did not have symptoms. The others, women aged 30 and 40, had mild respiratory problems. All are stable.
The WHO also yesterday confirmed two new cases in Saudi Arabia, one of which was a healthcare worker. It urged hospitals to take the issue more seriously.
We're getting so little detail in these reports that it's tempting to read great import into the smallest point. But the two latest Saudi cases are reportedly in intensive care, while these four doctors have few or no symptoms. Was this what happened with the original nosocomial outbreak in Jordan last year—a few minor cases along with some serious and fatal ones? (And why is MERS so fond of hospitals?)
