Classical swine fever: Unveiling the complexity through a multifaceted approach

Area of Science:

• Veterinary Virology
• Animal Pathology

Background:

• Classical swine fever (CSF), caused by the classical swine fever virus (CSFV), is a highly contagious viral disease impacting domestic and wild pigs globally.
• The CSFV belongs to the Flaviviridae family, genus Pestivirus, and is endemic in many pork-producing regions, including Asia, Central and South America, and the Caribbean.
• Clinical manifestations of CSFV infection vary widely based on virus strain virulence and host factors, ranging from acute mortality to subclinical presentations.

Purpose of the Study:

• To provide a comprehensive overview of Classical Swine Fever (CSF).
• To discuss the characteristics of the Classical Swine Fever Virus (CSFV).
• To highlight diagnostic approaches and control strategies for CSF.

Main Methods:

• Diagnosis of CSF involves serological detection, antigen detection, RNA detection, and virus isolation.
• Differential diagnosis is crucial as CSF symptoms and pathology can mimic African Swine Fever (ASF).
• Control strategies include vaccination, culling of infected animals, and carcass disposal.

Main Results:

• CSF presents with highly variable clinical signs and post-mortem findings, influenced by virus strain, pig age, and susceptibility.
• The economic significance of the swine industry makes CSFV a potential bioterrorism agent.
• Live attenuated CSF vaccines are available, demonstrating safety and efficacy.

Conclusions:

• Rapid intervention is essential for epidemic control in CSF-free areas.
• Management of CSF outbreaks necessitates prompt culling of affected pigs and proper carcass disposal (burial or burning).
• Understanding CSFV's characteristics is vital for effective disease management and prevention.
