A seroepidemiological survey to determine the prevalence of Crimean-Congo haemorrhagic fever (CCHF) virus among dairy cattle in Iran was carried out during 2006 and 2008. Blood samples were collected from 876 animals in five different provinces of the country. Sera were tested by a sandwich enzyme-linked immunosorbent assay (ELISA) for quantitative determination of antibodies to CCHF virus. Serological evidence of infection was noted in 52 (5.9%) of 876 dairy cattle. Antibody prevalence increased with age; 78.8% seroprevalence in cattle older than 3 years versus 21.2% in animals less than 2 years old. There was a difference between provinces representing north-east (11.7%) and east (2%) of Iran.
2006 年至 2008 年期间，在伊朗对奶牛进行了一项克里米亚-刚果出血热（CCHF）病毒血清流行病学调查，以确定其流行率。从该国五个不同省份采集了 876 头动物的血液样本。采用夹心酶联免疫吸附试验（ELISA）对血清进行定量检测，以确定对 CCHF 病毒的抗体。在 876 头奶牛中，有 52 头（5.9%）出现了感染的血清学证据。抗体流行率随年龄增长而增加；3 岁以上牛的血清阳性率为 78.8%，2 岁以下牛的血清阳性率为 21.2%。东北部（11.7%）和东部（2%）省份之间存在差异。
