Classical Swine Fever Virus (CSFV) is a highly contagious virus that affects domestic and wild pigs. It belongs to the Flavivirus family and is responsible for causing classical swine fever, a serious disease that can lead to high mortality rates in infected animals. The virus spreads through direct contact with infected pigs or contaminated materials, such as feed and equipment. Control measures for CSFV include vaccination, biosecurity practices, and surveillance. Infected animals may show symptoms like fever, skin lesions, and respiratory issues. Effective management is crucial to prevent outbreaks, as CSFV can have significant economic impacts on the swine industry.
