Developments and advances in the prevention and control of CSF in Yunnan Province

摘要

Yunnan Province is in the southwestern border area of China, bounded by three countries (Burma, Laos and Vietnam) and has a 4000 kilometre boundary. The administrative divisions are divided into eight national autonomous prefectures, five districts, three municipalities and 126 counties. The population of the Yunnan province is 410 million, of 26 nationalities. The total number of pigs is 420 million. The system of prevention and control of animal diseases has been gradually improving since 1980. Laws and decrees, technical standards and a network of prevention and control of animal disease epidemics have been enacted or established in Yunnan Province. We have effectively controlled the occurrence or outbreak of animal epidemics, and, especially in the prevention and control of CSF, have achieved remarkable success. The results of a continuous sampling survey for 10 years indicate that the mortality of pigs caused by CSF has dropped from 4.2 percent to 0.4 percent, and the number of dead pigs from 1.2 million in 1980 to 160000 in 1998. This paper briefly introduces the animal veterinary organisations, personnel and developments and advances in the diagnosis, monitoring and control of CSF in Yunnan Province.
