In February 2001, @entity4021 ( @entity4021 ) was confirmed in Great Britain. A major epidemic developed, which peaked around 50 cases a day in late March, declining to under 10 a day by May. By mid-July, 1849 cases had been detected. The main control measures employed were livestock movement restrictions and the rapid slaughter of infected and exposed livestock. The first detected case was in south-east England; infection was traced to a farm in north-east England to which all other cases were linked. The epidemic was large as a result of a combination of events, including a delay in the diagnosis of the index case, the movement of infected @entity742 to market before @entity4021 was first diagnosed, and the time of year. Virus was introduced at a time when there were many @entity742 movements around the country and weather conditions supported survival of the virus. The consequence was multiple, effectively primary, introductions of @entity4021 virus into major @entity742 -keeping areas. Subsequent local spread from these introductions accounted for the majority of cases. The largest local epidemics were in areas with dense @entity742 populations and livestock dealers who were active during the key period. Most affected farms kept both @entity742 and @entity291 . At the time of writing the epidemic was still ongoing; however, this paper provides a basis for scientific discussion of the first five months.
