South Korea’s agriculture ministry said on Tuesday it will carry out a nationwide vaccination for cattle against foot-and-mouth disease by Thursday in an attempt to prevent further spread of the virus.

The first case of infection of foot-and-mouth in nearly a year was confirmed on Monday at a dairy farm. A second case was confirmed at a cattle farm later the same day, and 243 cattle on the two farms were culled.

South Korea, Asia’s fourth-largest economy, regularly inoculates its cattle and hogs against three types of foot-and-mouth diseases, and the ministry said a wider spread of the virus was unlikely with this outbreak as it was one of the three types the country typically vaccinates against.

However, as the outbreak comes amidst South Korea’s worst-ever bird flu epidemic, the agriculture ministry ordered a nationwide re-vaccination of livestock as an extra preventative measure to contain the virus, a ministry spokesman said. The vaccination of all the country’s 3.14 million cattle is expected to cost about 5.3 billion won ($4.6 million).
