Abstract

African swine fever (ASF) outbreaks firstly occurred in Dien Bien province since March 06, 2019, then the disease had spread to 10/10 districts/cities with 100/130 towns and villages in Dien Bien province. The epidemiological indicators were determined basing on the epidemic reports from Sub-Department of Animal Health in the period 2019 - 2022. The results showed that the prevalence rate of ASF virus in localities of Dien Bien province was 26.36 - 76.92%. Pigs of all ages can be infected, in which, pigs are infected and destroyed mainly in the group of pigs and piglets (75.04%), lower than that of sows and boars (24.96%). The rate of disease and destruction accounts for 0.44 - 7.74% of the total number of pigs in the province. In 2019, Dien Bien province has a translation year coefficient of 2.93. The year 2020 to 2022 this coefficient was less than 1.
