Epidemiology of contagious bovine pleuropneumonia (CBPP) in Northern states of Nigeria. An update

Abstract

Data on reported outbreaks of contagious bovine pleuropneumonia (CBPP)and vaccination figures for a 20-year period (1970-1989) are plotted against the respective years to determine the relationship between the vaccination and number of outbreaks recorded in Nigeria. The result indicates that when vaccination was intensified between 1975 and 1986, the number of outbreaks were low. The number of affected herds and the total number of deaths recorded increased in the late 1980s. Data on the seasonal distribution of outbreaks showed that they mostly occurred during the dry season (October-March). When data collected on geographical locations were plotted in a map using the same references indicated in the outbreak files, it was observed that they tended to concentrate along river banks. Also, the disease situation in the neighbouring countries was related to our own control problems.
