ABSTRACT: The current study reports the outbreaks of
Peste des Petits Ruminants (PPR) in the small ruminant population of Pakistan.
The objectives were to understand the clinical picture of disease under field
conditions, estimate the basic epidemiological parameters for the local
population of small ruminants and to determine the spatial and temporal
distribution of PPR during 2005 to 2007 in Pakistan. A total of 62 outbreaks
were investigated among sheep and goat flocks in the five provinces of Pakistan
and Azad Jammu & Kashmir (AJK). The PPR virus activity in these outbreaks
was demonstrated by clinical picture and presence of PPR virus specific
antibodies by employing cELISA. The combined estimates of mean cumulative
morbidity and mortality for sheep and goats were estimated 65.37% and 26.51%
respectively with a case fatality of 40.40%. The species specific mean cumulative
morbidity, mortality and case fatality for goats were 68.80%, 29.45%
and 42.75% respectively, while these estimates for sheep were 48.77%, 14.98%
and of 26.16% respectively. These estimates for goats were significantly higher
