Fifty camels from Oman had Middle East respiratory syndrome antibodies in their blood, indicating they had exposure to the deadly virus at some point and leading researchers to think camels could be part of the chain that leads to human infections. Only 15 of 105 camels from other regions had MERS antibodies. Since the disease's identification in September, 46 of 94 people have died from the virus, closely related to the SARS virus that caused a pandemic in 2003. Bats or other animals may be possible contributing species because many of the people infected with MERS did not have direct contact with camels, according to the World Health Organization and the NIH.
