Contagious bovine pleuropneumonia in Tanzania: current status.
CBPP reappeared in Arusha, Northern Tanzania in 1990, having been introduced from Kenya. The disease spread rapidly to Mara region through rustling of sick or infected animals. In November 1992, an unrelated outbreak occurred in Kagera, having spread from Southern Uganda. Up to the end of December 1994, the disease appeared to be confined to Kagera and Arusha. In January 1995, CBPP was observed in Morogoro region, south of the central railway line. Thereafter, the disease spread through western Tanzania. More recently, further disease has occurred in the Southern Highlands and Central regions. The contaminated area now stretches roughly between latitudes 1 degree and 9 degrees S and longitudes 30 degrees and 37 degrees E, with a cattle population of about 10 million. The direct losses incurred as a result of animal mortality, and vaccination campaign and disease surveillance costs have been assessed at over US$11 million. Indirect losses resulting from chronic disease are much more difficult to assess but are believed to be even higher. Control of the disease has been through restricting animal movements and a mass vaccination campaign. Uncontrolled animal movement during transhumance, trade, cattle thefts and vaccination breakthroughs facilitated the spread of the disease.
