In 2012, a new betacoronavirus, Middle East respiratory syndrome coronavirus (MERS-CoV), was identified in humans. Several studies confirmed dromedary camels to be a potential reservoir and a source for human infection. Camels located on the Canary Islands were included in those studies and ca 10% of them were positive for MERS-CoV-specific antibodies. However, these findings could not be correctly interpreted because epidemiological information was not provided. Thus, further investigations were necessary to clarify these results. A total of 170 camels were investigated in this survey, of which seven (4.1%) were seropositive by ELISA. Epidemiological information revealed that all seropositive camels had been imported from Africa 20 or more years prior. We conclude that seropositive camels had contact with MERS-CoV in Africa and that there is no shedding of the virus among camels or people around the farms on the Canary Islands. However, the presence of antibodies in the camel herds should be monitored.
2012 年，一种新型贝塔冠状病毒——中东呼吸综合征冠状病毒（MERS-CoV）在人类中被发现。多项研究证实，单峰驼是潜在的储主和人类感染的来源。加那利群岛上的骆驼也被纳入了这些研究，其中约 10%的骆驼对 MERS-CoV 特异性抗体呈阳性。然而，由于没有提供流行病学信息，这些发现无法得到正确解释。因此，有必要进行进一步的调查以澄清这些结果。在这项调查中，共检查了 170 只骆驼，其中 7 只（4.1%）通过 ELISA 检测呈血清阳性。流行病学信息显示，所有血清阳性的骆驼均在 20 年或更早之前从非洲进口。我们得出结论，血清阳性的骆驼曾在非洲接触过 MERS-CoV，而且在加那利群岛的农场及其周围，骆驼或人群中没有病毒的传播。然而，应该监测骆驼群中抗体的存在。
