US reports third case of potential MERS virus
A third potential case of the dangerous Middle East Respiratory Virus, has been found in the United States.
The United States announced its first case earlier this month, a health care worker who had travelled to Riyadh at the end of April.
MERS causes fever, cough and shortness of breath, and can be lethal particularly among older people and those with pre-existing health problems.
Some 30 percent of the several hundred people infected with it have died, according to the US Centers for Disease Control and Prevention.
The virus first emerged in Saudi Arabia in 2012 and recent research has suggested it may originate in camels.
