Peste des petits ruminants (PPR) is an acute febrile viral disease of goats and sheep characterised by mucopurulent nasal and ocular discharges, necrotising and erosive stomatitis, enteritis and pneumonia. The disease is endemic in India and causes large economic losses each year due to the high rates of mortality and morbidity in infected sheep and goats. The present study reports observations from 58 laboratory confirmed outbreaks of PPR and provides details of the prevalence of antibodies to PPR virus (PPRV) in 4,407 serum samples of small ruminants. Most of the clinical specimens used for the study originated from the northern and central parts of India. Serum samples used for the detection of antibodies to PPRV were derived from a greater number of regions within the country, however, these samples may not be a true representation of the target population (unvaccinated sheep and goats over 3 months old). Indigenously developed monoclonal antibody-based diagnostic kits were used for the detection of PPRV antigen (sandwich enzyme-linked immunosorbent assay [ELISA]) and antibody (competitive ELISA).
