title: [Epidemiological features of human brucellosis in the rural areas in Shandong during 1990-1996].
abstract: Epidemiologic features of Brucellosis in the rural areas in Shandong in the 90's were studied and analysed by means of epidemiological and statistical methods. Results indicated an increasing trend in incidence of the disease (Trend tast: chi 2 = 76.06, P < 0.01). Cases mainly concentrated in few economically poor regions connecting Jinan, Zibo, Binzhou and Weifang cities or prefectures. The patients showed serious and classical clinical symptoms. More cases under 14 years and over 60 years old were seen than before. The epidemic peak has been advanced with the epidemic strain B. melti. III identified. Mismanagement on animal quarantine, eradication of infected animals and vaccination in those poor areas accounted for the major reasons of the recurrence.
