“…As evidenced by W and P-values, the results of disease signs matrix scoring indicated that pastoralists were able to characterize most of the overt clinical characteristics of cattle diseases in general and FMD in particular. Indeed most of the signs listed for FMD and scored by pastoralists were consistent with what is known and recorded about FMD in veterinary literatures and textbooks (Sobrino et al 2001;Vosloo et al 2002;Catley et al 2004;Kahn 2005). In pastoral communities, people spent most of their lives in close proximity to livestock and, to a large extent, their survival depends on the ability to manage their animals (Catley 2006).…”

“…However, 'haleb' was ranked as fourth most important disease by pastoralists indicating its serious impact when it occurred. Since the occurrence of 'habeb' was very low usually less than 1% as reported by Tadesse (2003) and Catley et al (2004), pastoralists associate the significance of FMD with haleb than habeb. Furthermore, in agreement with Tadesse Fig.…”

Foot and mouth disease (FMD) is the most economically important disease of livestock that still affects extensive areas of the world. This study described the use of participatory appraisal tools such as pair-wise ranking, matrix scoring and proportional piling to assess the perception of livestock keepers about the clinical signs and epidemiological features of cattle diseases with particular emphasis on FMD. Strong agreement among informant groups (W = 0.710; P = 0.000) in pair wise ranking indicated that the diseases were common problem to all the selected districts. Matrix scoring of disease indicators/signs also showed strong agreement (W = 0.504 to 0.955; P = 0.000) that implied significant current veterinary knowledge by Afar pastoralists. Age specific means of annual incidence rates estimated by proportional piling were significantly (P < 0.05) different but negatively correlated for FMD, CBPP and pasteurellosis. However, correlation was not significant for anthrax, blackleg and other important diseases. Age specific means of annual mortality was significantly (P < 0.05) but negatively correlated for FMD, CBPP, pasteurellosis and other important cattle diseases with correlation coefficients of -0.72, -0.81, -0.8 and -0.55, respectively. However, correlation (r = 0.12) was not significant for anthrax and not correlated at all for blackleg. This study indicated that pastoralists have detailed knowledge about their livestock health problems, and hence the combined use of participatory appraisal and conventional methods is essential for an ultimate disease control strategy.

“…Proportional piling was used to estimate the annual incidence and mortality of acute and chronic forms of FMD, using the method described by Catley et al (2004). Informal interviews with pastoralists indicated that they categorized cattle into four main age groups as follows: waatiye/jabiye aged from birth to two years; raada/jibicha aged two to three years; goromsa/ kurkura aged three to four years; hawicha/korma aged greater than four years.…”

Participatory epidemiology (PE) was used on the Borana plateau of southern Ethiopia to understand pastoralist's perceptions of the clinical and epidemiological features of foot and mouth disease (FMD) in cattle. Matrix scoring showed good agreement between informant groups on the clinical signs of acute and chronic FMD, and findings were cross-checked by clinical examination of cattle and assessment of previous clinical FMD at herd level by detection of antibody to non structural proteins of FMD virus. The positive predictive value of pastoralist's diagnosis of FMD at herd level was 93.1%. The annual age-specific incidence and mortality of acute FMD in 50 herds was estimated using proportional piling. The estimated mean incidence of acute FMD varied from in 18.5% in cattle less than two years of age to 14.0% in cattle three to four years of age. The estimated mean mortality due to acute FMD varied from 2.8% in cattle less than two years of age to 0.3% in cattle three of age or older. Pearson correlation coefficients for acute FMD by age group were -0.12 (p>0.05) for incidence and -0.59 (p<0.001) for mortality. Estimates of the annual incidence of chronic FMD varied from 0.2% in cattle less than two years of age to 1.8% in cattle three to four years of age. The Pearson correlation coefficient for the incidence of chronic FMD by age group was 0.47 (p<0.001). Outbreaks of FMD peaked in Borana cattle during the two dry seasons and were attributed to increased cattle movement to dry season grazing areas. The mean seroprevalence of FMD was estimated at 21% (n=920) and 55.2% of herds (n=116) tested seropositive. Serotyping of 120 seropositive samples indicated serotypes O (99.2%), A (95.8%), SAT 2 (80%) and C (67.5%). The endemic nature of FMD in Borana pastoral herds is discussed in terms of the direct household-level impact of the disease, and the increasing export of cattle and chilled beef from Ethiopia.

“…Seroprevalences for FMD virus-specific antibodies in pastoralist cattle of various ages were estimated as follows: 9% in Orma herds in Kenya, 9.5% in Maasai and Sukuma herds in Tanzania (Catley et al 2004) and 15.8% in South Sudan (Barasa et al 2008). In Borena of Ethiopia, 21% (Rufael et al 2008) and 53.6% (Mekonnen et al 2011) seroprevalence was noted for the sub-types A, O, SAT 1, SAT 2 and SAT 3.…”

“…A sequel to FMD frequently described in African cattle is the complex of clinical signs referred to as 'heat-intolerance syndrome' (HIS). The condition is characterized by intolerance to heat, and affected animals show pronounced panting, increased body temperature and pulse rate during hot weather, and abnormal hair growth (Catley et al 2004;Barasa et al 2008;Arzt et al 2011a, b).…”

This study was conducted to estimate impacts of foot-and-mouth disease (FMD) on producers' livelihoods in Borena zone, southern Ethiopia, using participatory appraisal methods and secondary data sources. Livestock-related livelihood options accounted for 31% of the total means of food and income sources followed by crop farming. This study clearly showed that FMD had the greatest impact on the cattle-derived benefits. FMD outbreak frequencies were found to be significantly correlated to the length of extended dry season (r = 0.377). In addition, FMD is ranked as the number one cattle disease after 1985 with significant rank change (t = 12.04) as compared to 1984 and before. Considering the impacts of FMD on peoples' livelihoods, FMD effective control strategies would reduce stress on people's lives, improve food security and keep social harmony.
