Abstract

In north-east India, pig farming is a main source of livelihood since 80% of households rear pigs and pork is a key part of the local diet. The classical swine fever disease may run as acute, sub acute, chronic, late onset or in apparent course, depending on a variety of viral and host factors. The morbidity and mortality rates are high during acute infections and the case fatality rate can approach 100 percent. In chronic form, pigs which are clinically normal are persistently viraemic and important intermittent shedders of virus until dying in 6–12 months. In such cases, treatment is not possible and affected pigs must be slaughtered and the carcasses buried or incinerated. The variability of the clinical signs and post-mortem lesions do not provide firm evidence for unequivocal diagnosis. A tentative diagnosis based on clinical signs and post-mortem lesions must therefore be confirmed by laboratory investigation. By sanitary prophylaxis and vaccination with modified live virus strains is very effective in preventing losses where classical swine fever is enzootic. This information will help the farmers in generating awareness to prevent spread of disease.
