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.
