Exploratory Report of Wild Boar Surveillance and Epidemiological Course of African Swine Fever Outbreak; Case in the Republic of Korea From 2019 to 2023.

ABSTRACT: In October 2019, the first cases of African swine fever (ASF) were confirmed in wild boar in the Republic of Korea (ROK). Since then, ASF has continued to spread throughout the country, particularly among wild boar populations, despite intensive efforts to contain the outbreak. Our objective was to assess the results of current ASF surveillance in wild boars and identify various risk factors related to ASF outbreak in ROK. Between September 2019 and June 2023, a total of 122,078 wild boar samples were submitted, with 3135 tested as positive to ASF infection. Among them, 90.6% (2839/3135) of ASF-positive cases were detected from carcasses. Within the carcass samples, ASF prevalence showed an increase from 5.98% (95% confidence interval [CI] 4.47-7.81) to 37.15% (95% CI 34.12-40.27) through
