Researchers searching for signs of Middle East respiratory syndrome coronavirus (MERS-CoV) in different livestock animals have found antibodies specific to the new virus in dromedary camels. This suggests that these animals have encountered MERS-CoV, or a closely related virus, and may be one reservoir of the virus that is causing MERS in humans. The results of this study, led by RIVM-researchers, are published today in The Lancet Infectious Diseases.
