The 2019 African swine fever outbreak in Vietnam was caused by a p72 genotype II strain identical to those from China (2018) and Georgia (2007).
African swine fever is one of the most dangerous diseases of swine. We confirmed the 2019 outbreak in Vietnam by real-time reverse transcription PCR. The causative strain belonged to p72 genotype II and was 100% identical with viruses isolated in China (2018) and Georgia (2007). International prevention and control collaboration is needed.
