Abstract

An epidemiological study was undertaken to assess the crude and specific measures of morbidity, mortality and case fatality against Peste des petits ruminants (PPR) in small ruminants. A total of 18 PPR outbreaks were selected by active and passive surveillances in North-west agroclimatic zone of Tamil Nadu, India. Overall morbidity, mortality and case fatality rates were 3.18%, 1.09% and 34.28% respectively which is lower than the earlier reports. Morbidity and mortality rates were higher in goats in comparison with sheep indicating that goats are more susceptible to infection. Morbidity, mortality and case fatality rates were higher in young animals than adults for both species. Infection and severity of the disease were more in non-descript and Mecheri breeds of sheep and Tellicherry and Jamunapari breeds of goats. Infection rate and severity of the disease were more in males and females of both species respectively. The present study concludes that species, age, breed and gender predisposing exist in the outbreaks of PPR.
