From Foreign Policy:

A SARS-like disease that kills a third of those it infects is suddenly, and mysteriously, surging inside [Saudi Arabia]…. It’s called the Middle East respiratory syndrome (MERS), and though the majority of the cases have been found in Saudi Arabia, 14 other countries have reported instances. Make that 15: Egypt just reported a case at the end of April….

Among [the cases outside Saudi Arabia], at least two were among religious pilgrims: The first pilgrim, from Malaysia, reportedly drank camel’s milk in Jeddah before returning home ….

Unfortunately, though camel’s milk and bats are indeed involved, staying away from them isn’t enough, since the virus can be spread from human to human.
