African swine fever.

The continuing spread of African swine fever (ASF) outside Africa in Europe, the Russian Federation, China and most recently to Mongolia and Vietnam, has heightened awareness of the threat posed by this devastating disease to the global pig industry and food security. In this review we summarise what we know about the African swine fever virus (ASFV), the disease it causes, how it spreads and the current global situation. We discuss current control methods in domestic and wild pigs and prospects for development of vaccines and other tools for control.
