Classical Swine Fever-An Updated Review.

Area of Science:

• Veterinary Virology
• Animal Infectious Diseases
• Pestivirus Research

Background:

• Classical swine fever (CSF) is a major transboundary viral disease affecting swine worldwide.
• Caused by the CSF virus (genus Pestivirus), it presents diverse clinical signs necessitating laboratory confirmation.
• Wild boars act as a reservoir, posing a risk of transmission to domestic pig populations.

Purpose of the Study:

• To provide a comprehensive, updated review of Classical Swine Fever.
• To cover virus properties, clinical manifestations, epidemiology, pathogenesis, and immune responses.
• To detail diagnostic methods and current vaccination strategies for CSF.

Main Methods:

• Review of existing literature on CSF virus properties and epidemiology.
• Analysis of diagnostic techniques, including direct and indirect methods.
• Evaluation of control strategies, encompassing quarantine, culling, and vaccination.

Main Results:

• CSF virus exhibits genetic diversity (three genotypes) not directly correlating with virulence.
• Clinical presentation varies widely based on virus and host factors.
• Control strategies differ significantly between epidemic-free and endemic regions.

Conclusions:

• Effective control of Classical Swine Fever requires understanding its epidemiology and utilizing appropriate diagnostic tools.
• While culling and quarantine are primary in disease-free areas, vaccination remains crucial for managing endemic infections.
• Continued research into virus properties and immune responses is vital for improved disease management.
