Comparative Observation Between Human Brucellosis And Leptospirosis by Gender, Age and Oc- cupation in Korea, 2001-2010 Brucellosis Leptospirosis 95% CI: Conﬁdence interval of 95%, Chi-square analysis indicated a signiﬁcant difference from the total value.*p < 0.05, **p < 0.01. of the cases of HB were occurred in 40- to 59-year-old age group, and that of HL was clearly showing a high incidence in the elderly age that over 60-year-old (59.6%) (p < 0.01). The distribution of HB cases by occupation was as fol- lows: farmers, veterinarians and others, and the others, the percentages were 57.9%, 6.1%, and 30.1%, respectively. However, the distribution by occupational groups was broad- ly in HL as follows: famers, jobless, mistress, clerk and ser- vicemen, labor, students, engineers, salesman, soldiers, and the others, the percentages were 52.2%, 14.0%, 5.9%, 3.8%, 1.3%, 1.3%, 1.3%, 0.7%, 0.7%, and 18.8%, respectively. In Korea, recently, most young people move to cities for work and elderly people are left to work as farmers on their own land [9]. Thus, the higher incidence in the elderly of farm- ers may be caused by increased risk of infection due to their engaging in increased outdoor activities in rural areas. Despite the widespread infelicity of HB and HL, pre- vention of focal transmission in high-risk areas, and insani- tary workplace is necessary. Transmission can be minimized through the health education of residents and travelers in high risk areas, recommending for public health and sanitary education of farmers, protective clothes or masks, limiting access to endemic areas, or taking other appropriate prophy- lactic measures [3, 6, 9]. In conclusion, this is comparative observation of epide- miological aspects for HB and HL in Korea during the period of 2001 to 2010. The difference in HB and HL risk factors reﬂects the different inﬂuences of hosts/vector, climate, and geographical and environmental characteristics in the epide- miological patterns. It is hoped that this information will be a useful reference in the further studies of HB and HL for the public health service. Conﬂict of Interest None References 1. 2. Corbel MJ.
