Three more wild boars found dead near the border with North Korea have been confirmed to be infected with African swine fever (ASF), bringing the number of ASF cases to 86 in South Korea.
 
The National Institute of Environmental Research on Saturday confirmed the detection of the ASF virus in the three pigs whose carcasses were discovered by local residents in Paju.
 
The carcasses found on Thursday and Friday inside the Civilian Control Line were buried later and the area sterilized to prevent the spread of the disease.
 
Of the 86 confirmed ASF cases from wild boars, 31 were from Paju, a town near the border with North Korea.
 
There is at present no vaccine or known cure for ASF. Though the disease is not harmful to humans, the fatality rate is close to 100 percent for pigs.
