Abstract: To investigate the epidemic distribution of Chuzan disease in China, a total of 8 232 cattle, goat and sheep sera derived from 13 provinces in China between 2016 and 2018 were detected for the antibodies against Chuzan virus (CHUV) by C-ELISA test. The results showed that the CHUV antibodies were observed in 12 provinces, the positive rate of CHUV increases from north to south (0-74.03%), and the infection rate in autumn (September to November) was the highest (2.50%-60.00%), which was significantly higher than that in spring (0-10.00%) and summer (2.22%-35.00%). Detection of sera from cattle, goat sand sheep in Ulanchab, Hami, Hechi and Qujing were conducted, the results showed that the positive rate of cattle sera was higher than that of goat and sheep serum. On the one hand our findings showed that the Chuzan disease was prevalent and provide the reliable reference regarding CHUV surveillance in China, on the other hand it was verified that the prevalence of CHUV was closely related to the activities of its media insects and has obvious regional and seasonal characteristics.
