title: A retrospective study of the extensive eradication program for brucellosis outbreaks and control in Korea, 2002-2009.
abstract: This study concerns the quantitative analysis of brucellosis outbreaks and the related risk  factors and control programs for both domestic cattle and human brucellosis infections in Korea between  2002 and 2009. There were a total of 77,082 infections of bovine brucellosis (BB) in domestic cattle with a  prevalence rate (PR) of 13.3 per 1,000 cattle; during the same period there were 620 cases of human  brucellosis (HB) with a PR of 0.16 per 100,000 persons. Moreover, the correlation coefficient of  brucellosis outbreaks between cattle and humans was highly significant (r = +0.985). The attack ratio of HB  cases was 8.04 per 1,000 BB cases. The distribution of brucellosis outbreaks was concentrated in the  southeast region of Korea (P < 0.01). Significantly more males were infected than females (86.9% versus  13.1%), and a high incidence of HB was observed in those aged more than 40 years (86.1%). The majority of  HB cases occurred primarily among rural inhabitants (92.3%) and among famers and related workers (47.9%).  Finally, all of the measures that were applied in the extensive eradication program for brucellosis  outbreaks and control were based principally on an intensive test-and-slaughter policy and contributed  significantly to the reduction in the outbreaks of brucellosis in Korea.
