Analysis on the Prevalence Status of Yak-derived Bovine Coronavirus in China
In order to investigate the prevalence status of yak-derived bovine coronavirus（BCoV） in China，relevant testing results in main production regions of yak were summarized and analyzed by means of reviewing literature. As it was found that，since 2012，BCoV had been widely prevalent in the main provinces（autonomous regions），including Qinghai，Sichuan，Xinjiang and Tibet，with a high infection rate，and the average positive rates of serum antibodies in most regions were above 80%，the positive rates of pathogens were above 60%. In order to control the disease，a series of measures should be carried out，such as，strengthening husbandry management，preventing any mixed infection，and striving to isolate and purify the virus. However，there were few epidemiological reports due to late beginning of BCoV study in China，it was necessary to further strengthen relevant investigation and research on the pathogenic mechanism，prevalence and control technology of the disease. This study would provide some references for identification of BCoV prevalence and its prevention and control in China.
