Abstract
Since African swine fever virus (ASFV) introduction into Vietnam in 2019, most ASFV strains detected in this country belong to the p72 genotype II and intergenic region (IGR) II variant. Further investigation of the intergenic region of ASFVs isolated in the Capital Hanoi region showed two different variants, IGR I and IGR II, which were located between the I73R and I329L genes of the p72 genotype II ASFV strains. This finding suggests co-circulation of two ASFV variants in the domestic pig population in Vietnam.
