Risk factors for foot and mouth disease seroprevalence in indigenous cattle in Southern Ethiopia: the effect of production system

Abstract Background Foot-and-mouth disease (FMD) is a highly contagious viral disease of cloven-hoofed animals. As a transboundary animal disease, the prevention and control of FMD are important. This study was based on spatial multi-criteria decision analysis (MCDA) to assess FMD risk areas in mainland China. Ten risk factors were identified for constructing risk maps by scoring, and the analytic hierarchy process (AHP) was used to calculate the criteria weights of all factors. Different risk factors had different units and attributes, and fuzzy membership was used to standardize the risk factors. The weighted linear combination (WLC) and one-at-a-time (OAT) were used to obtain risk and uncertainty maps as well as to perform sensitivity analysis. Results Four major risk areas were identified in mainland China, including western (Xinjiang and Tibet), southern (Yunnan, Guizhou, Guangxi and Guangdong), northern (Gansu, Ningxia and Inner Mongolia), and eastern (Hebei, Henan, Anhui, Jiangsu and Shandong). We found spring as the main season for FMD outbreaks. Risk areas were associated with the distance to previous outbreak points, grazing areas and cattle density. Receiver operating characteristic (ROC) analysis indicated that the risk map had good predictive power (AUC = 0.8532). Conclusions These results can be used to delineate FMD risk areas in mainland China, and provinces can adopt the targeted preventive measures and control strategies.

Effect Of Age

The present study was performed in the Upazila Veterinary Hospital, Meghna, Comilla during the period from September 2006 to February 2007 to observe the prevalence of Foot and Mouth Disease (FMD) in cattle at Meghna upazila in Comilla. A total of 253 skin diseased cattle head were examined in this study where 109 were males and 144 were females. The prevalence of FMD was 24.51% at Meghna upazila. The effect of age, sex, breed, season and farming system on the incidence rate of the disease was discussed. Seasonal variation on outbreak of this disease was significantly higher. The clinical prevalence of FMD was highest in the month of November (34.69%) and December (36.20%). The males (35.77%) were more susceptible than females (15.97%). The adult cattle (34.18%) were more susceptible compared to heifer (23.43%) and young (09.72%). In breed, 39.18% indigenous breeds and 15.38% crossed breeds were infected by FMD. So, it could be concluded that the rural farming system, adult, male and the indigenous cattle were more susceptible to FMD in winter season.
