Middle East Respiratory Syndrome Coronavirus (MERS-CoV) is a camel-borne zoonotic virus endemic across Eastern Africa and the Middle East, with evidence of circulation in Bangladesh and Mongolia. To determine if MERS-CoV was present in Kazakhstan, in 2017-2018, we collected swabs and sera from Bactrian camels (n = 3124) and dromedary (n = 5083). The total seropositivity was 0.54% in Bactrian camels and 0.24% in dromedaries; however, we did not detect MERS-CoV RNA in swab samples. There was no difference in the probability of infection between species or sex, but younger camels had a higher probability of being seropositive, suggesting a recent introduction of the virus to Kazakhstan. The infection of both camel species indicates that they both may play a role as natural reservoirs. These results reinforce the need for continual surveillance, especially at the camel-human interface to understand the risk of zoonotic exposure.
