Scientists are soon to test cats, dogs and even rats as they seek to understand the mysterious Mers infection. Middle East Respiratory Syndrome was first discovered in 2012 and has so far killed about 200 people globally.
While the virus that causes it has been found widely in camels, researchers say it could be lurking in other species. One expert told BBC News that the hunt was likely to extend soon to animals that had close contact with people. Mers was originally found in a patient from Bishah in Saudi Arabia but since then almost 600 cases of the infection have been discovered around the world, with about 30% of those who get sick dying from the illness. Researchers believe the coronavirus that causes the infection crossed over from animals.
