Classical Swine Fever in Wild Hog: Report of its Prevalence in Northeast India

A first-of-its-kind study reports the prevalence of Classical Swine Fever (CSF) in wild hogs across Northeast India, marking a significant finding for the region's epidemiology. The research identified three isolated cases of CSF in wild hogs from Kaziranga, Manas, and Jaldapara National Parks, confirming the virus' presence through post-mortem analysis, histopathological findings, and detection of the CSFV genome in affected tissues. Additionally, CSF-specific antibodies were detected in two wild hogs and eighteen feral pigs, suggesting widespread exposure. Phylogenetic analysis linked the isolates to genotype 2.2 of Indian CSFV strains, highlighting potential implications for disease transmission dynamics in the region. This study provides critical insights into the epidemiology and biology of CSFV in wild animals, filling a significant gap in understanding its spread.
