Key result
Large herd size was significantly associated with foot and mouth disease seropositivity in cattle compared to small herd size (OR 6.05; 95% CI 2.54-14.43; p<0.05).
Why the study?
The study was conducted to estimate the seroprevalence of foot and mouth disease virus in cattle and assess associated risk factors in selected districts of the Afar region.

Foot and mouth disease is highly prevalent among cattle in the Afar region of Ethiopia, with larger herd size and wildlife contact identified as significant risk factors.
BACKGROUND: A cross-sectional study was conducted from November 2018 to May 2019 to estimate seroprevalence of foot and mouth disease virus for cattle and assess associated risk factors in selected districts of afar region. Simple random sampling technique was employed to select the study areas. A total of 384 bovine sera were collected from 72 herds and seroprevalence of the disease was determined using 3ABC-ELISA technique. Data were recorded and coded using Microsoft Excel spread sheet and analysed using STATA. Potential risk factors of the disease were also assessed using logistic regression analysis. RESULTS: Out of 384 sera tested at National Veterinary Institute, the overall seroprevalence of foot and mouth disease (FMD) virus was 19.8% (n = 76; 95% CI = 15.8-23.79) at animal level and 56.94% at herd level. The herd level seroprevalence was higher in animals tested from Dubti (85%, n = 17) than Asayita (48.13%, n = 13) and Chifra (44%, n = 11). Among the associated risk factors, age, herd size, district and contact with wild life were statistically associated with foot and mouth disease serostatus (p < 0.05). Medium and large herd size animals were 2.49 (95% CI: 1.33-6.63) and 6.05 (95% CI: 2.54-14.43) times more likely to develop the disease as compared to animals from small herd size, respectively. CONCLUSIONS: The current study finding revealed that FMD was more prevalent and economically significant disease in the study districts. Hence, further studies ought to be conducted to estimate the region wise serostatus magnitude of the disease, to assess its economic impact and to identify the circulating serotypes and strains in the areas.

Dubie et al. (2021) conducted a cross-sectional in Foot and mouth disease (FMD) (n=384). Large herd size vs. Small herd size was evaluated on Seroprevalence of foot and mouth disease (FMD) virus (OR 6.05, 95% CI 2.54-14.43, p=<0.05). Large herd size was significantly associated with foot and mouth disease seropositivity in cattle compared to small herd size (OR 6.05; 95% CI 2.54-14.43; p<0.05).
