Abstract
Purpose. Peste des Petits Ruminants (PPR) is a highly contagious viral disease of sheep and goats. The disease is considered to be one of the main constraints to the productivity of small ruminants in the Sub-Saharan countries including Nigeria and the globe at large. This work is aimed at assessing the risk factors associated with the prevalence of PPR in Makurdi.
1. Introduction
The study was conducted in four township areas of Makurdi Local Government Area (Longitude 8.5º E and Latitude 7.74ºNorth) of Benue State designated as blocks. They include: North-Bank (in the North), Wurukum (in the Central area), Wadata (in the South) and Modern Market/Ankpa Ward (in the west). The annual rainfall is between 1200-1500mm and mean temperature of 21ºC-30 ºC [10]
Eleven risk factors were assessed using a structured questionnaire for every sampled herd. Ten different factors (with p-value ≤ 0.05) were found to be associated with PPR as shown in (Table 1).
3.2. Multivariate analysis using Logistic regression
Furthermore, Summary percentage distribution of PPR prevalence
based on localities in Makurdi is presented in (Table 3).
Assessment of risk factors is
important for effective control and eradication of PPR in
this study, the overall prevalence of PPR in Makurdi was found to be 51.3%.
From all the locations, North-Bank was found to have the highest PPR prevalence
in Makurdi with prevalence rate of 64%. This may be attributed to the high
small ruminant population in North-Bank area as the International Cattle Market
which also serves as a goat and sheep market (where the major large and small ruminant
transactions in Makurdi takes place) is situated there.
Wurukum, Wadata and Modern Market areas had prevalence rates of 60%, 36.5% and
41% respectively. This study showed that the overall prevalence (51.3%)
was low as compared to some other previous studies; for example, 54% by [11], 61.8% by [12],
62.8% by [13], and 70.2% by [14]. This variation might be due to the wide-coverage
of vaccination against PPR in 2010 and 2011 (Mai,
et al. 2004). These findings agreed
with the reports of [15].
