| Abstract | Early detection of animal diseases is one of the primary aims of epidemiosurveillance networks in western and central Africa. A sufficiently high sensitivity is an essential characteristic of an epidemiosurveillance network. Foot and-mouth-disease (FMD) is a highly contagious viral disease that affects all artiodactyla. It is included in the list of diseases monitored by the national animal disease epidemiosurveillance network (REPIMAT) in Chad. Surveillance of this disease is passive and primarily concerns bovine. Numerous bovine clinical suspicions are raised annually by the epidemiosurveillance network, but they are only rarely further investigated in the laboratory. A serological survey was conducted in the cattle population in eight of the nine administrative regions of the country (regions with the highest bovine densities) with the aim to evaluate the sensitivity of REPIMAT for FMD. The samples randomly selected were analysed in the OIE/FAO FMD reference laboratory at IZSLER, Brescia (Italy) with the support of EuFMD (The European Commission for the control of foot-and-mouth disease). Antibodies against non-structural proteins (NSP), indicative of recent or past infection, were analysed by a 3ABCELISA. A total of 106 villages/herds and 796 cattle were investigated. The herd-level seroprevalence was 63% (95% CI: 51.9-71.2) and the animal-level seroprevalence was 35.6% (95% CI: 32.239.0). A global significant positive relation was found between the estimated seroprevalence and the number of registered clinical suspicions. However, this relation is weak but heterologous and this could lead to an improvement of the declaration of FMD suspicions in some administrative regions where some correctives measures could be introduced. |
