map of ASF in ChinaAfrican swine fever virus (ASF) is a serious, highly contagious, viral disease. Recently, several cases of ASF have been confirmed in numerous Chinese provinces. U.S. swine industry organizations are working continuously on prevention and response to help keep ASF out of U.S. pig farms. ASF cannot be transmitted to humans, so it is not a public health or food safety concern. However, it can spread rapidly in pig populations by direct or indirect contact, and there is currently no vaccine or treatment. That’s why it is essential for the U.S. swine industry to be well informed and well prepared should an ASF outbreak ever reach the United States. This page provides a wealth of ASF resources.
