Abstract: The objective of this study was to investigate the epidemic of three viral diarrhea diseases of yaks in northwest Sichuan province and provide certain scientific basis for controlling this kind of disease. 1070 yak serum samples from 8 counties of Aba state in northwest Sichuan province were detected by enzyme-linked immunosorbent assay (ELISA) to investigate prevalence of BVDV, BCV and BRV. The results showed that the average positive rates of BVDV, BCV and BRV antibody were 44.3%, 84.1% and 94.4%, respectively. The BVDV, BCV and BRV of yaks were widespread in northwest Sichuan province, further comprehensive prevention and control measures of viral diarrhea diseases should be strengthened in this region.
