Rinderpest, capable of wiping out entire herds of cattle within days |
The virus causes respiratory disease and gut problems that lead to diarrhoea, dehydration and death. Over 80 per cent of cattle who contract it die from it. According to Dr Michael Baron of the Institute for Animal Health, "there has never been such a devastating disease in livestock".
Its last known outbreak was in Kenya in 2001, though it was thought to have lingered on in Somalia.
