Abstract:
An investigation into the epidemiological characteristics of African Swine Fever (ASF) in pig herds in Dien Bien province from 2020 to 2024 revealed that outbreaks occurred each year throughout the study period. A major outbreak occurred in 2021, affecting 7 out of 10 districts in the province and involving 1.77% of the provincial swine population. All infected pigs either died or were culled, resulting in significant economic losses for the local swine industry. In 2023 and 2024, although ASF re-emerged in 8 out of 10 districts, early detection and rapid response kept outbreaks limited in scale and economic impact. All pig categories-including boars, sows, fattening pigs, and piglets,were susceptible to infection. The endemicity level of ASF was moderate throughout the investigation period. Effective disease prevention and control measures are essential for preventing future ASF outbreaks in local pig herds.
