Prevalence of Classical Swine Fever Virus in India: A 6-Year Study (2004-2010)

A study was undertaken regarding the prevalence of classical swine fever virus (CSFV) antibodies and antigens in sera and suspected tissue samples of domestic pigs. The samples were received between January 2004 and September 2010. A total of 594 serum samples from 12 states and 287 tissue samples from 13 states of India were tested using commercial enzyme-linked immunosorbent assay (ELISA) kits. The mean prevalence of CSFV antibodies in suspected sera was 63.3% (376/594), whereas 76.7% (220/287) of the suspected samples were found to contain CSFV antigen. The high prevalence of CSFV antibodies suggests that the disease is endemic in the country. This baseline data will be of use in the formulation of control and eradication programmes.
