Bovine Brucellosis is a widespread, economically devastating and highly infectious zoonosis caused by Brucella abortus. In cattle it causes premature abortion around five to seven months into the normal nine month gestation and the disease can be transferred to humans through milk. Great Britain (GB) has been “Officially Brucellosis Free” (OBF) since 1991 and it is in the country’s best interest to maintain this status. There have been three reintroductions of the disease since 2003, the most recent in a beef herd in Cornwall 2004 (DEFRA, 2004). Such outbreaks threaten the UK’s OBF status. By identifying epidemiological risk factors and using data from the Cattle Tracing Scheme for GB (CTS) we examined the spatial and temporal patterns of births for both the whole of GB and the South West region in particular and used this information to identify risk periods due to cattle births. Then cattle movements originating from, or ending in Cornwall (the location of the last outbreak) were identified from the CTS database. A subset of 57 000 high-risk, potentially infectious, moves were identified and examined to establish the potential spatial spread of the disease from these movements.
