The samples were collected from 352 pigs suspecting with clinical symptoms of CSFV at many pig farms in 9 provinces in Viet Nam. The collected samples were evaluated for the presence of CSFV and other pathogens by PCR method. The studied results showed that the rate of CSFV-positive cases was 25.85% (91/352), of which this rate in 2017 and 2018 was more than 34.2%, and in 2019 it was 12.95%. In addition, out of 91 positive cases, 50 cases (54.95%) were only recorded to be positive with CSFV, 30 cases (32.97%) were co-infected with 1 other pathogen, 7 cases (7.69%) showed co-infection with 2 other pathogens, and 4 cases (4.40%) showed co-infection with 3 other pathogens. The study has contributed a clear picture of CSF and its co-infection with other pathogens in pigs in Viet Nam
