Abstract

African swine fever was endemic in Africa, some regions in Europe and Sardinia. Recently, this disease has been increasing remarkably due to the outbreak occurring in new areas such as East Asian countries or the ASEAN region. However, there is risk of ASF outbreak in Thailand because this disease has been reported in neighboring countries that are border including Myanmar, Vietnam and Cambodia. African swine fever is significant in the pig industry which can caused acute death and high mortality rate in infected animals. Moreover, there has no specific drugs and vaccines for prevention. If there is an outbreak of ASF disease in Thailand, it will be difficult to control the spreading because the virus is distributing easily and tolerance in the environment. Moreover, this disease will be a new disease that has never occurred before or emerging infectious disease. This article discusses the nature of African swine fever in pigs, diagnosis, epidemiology and various interventions used to prevent African swine fever. This study provides data as a guideline for monitoring the disease situation and disease prevention in order to reduce the destruction that will happen when the outbreak occurs and use as a guideline for future studies.
