Brucellosis, the most common zoonosis globally, is considered a major public health problem.
A retrospective study was carried out over 21 years (1998-2018) to determine the epidemiological features of human brucellosis in the province of El-Oued (south-eastern Algeria).
1,832 confirmed cases of human brucellosis were reported during the study period, with an average incidence rate of around 12.26 cases per 100,000 inhabitants. The annual distribution of the incidence was characterized by an increasing trend and a strong fluctuation ; its values ranged between 2.27 and 24.96 per 100,000 inhabitants. The monthly distribution showed that the highest incidence rates were recorded from mid-February to July, with a peak of 2.74 cases per 100,000 inhabitants in April.Human brucellosis has affected all municipalities. The highest incidence rate was observed in border municipalities such as Ben Guecha and Oum Tiour (89.76 and 66.14 per inhabitants, respectively).The incidence in the male population was higher than that of the female at 14.63 versus 9.83 per 100,000 inhabitants, respectively, noting that it increases with age. Individuals over 65 years are the most at risk, with an incidence rate of 22.32 per 100,000 inhabitants.
Along with strengthening preventive measures in the population, eliminating brucellosis in animals is the most effective method to protect humans against infection.
布鲁氏菌病是全球最常见的人畜共患病，被视为一个主要的公共卫生问题。
开展了一项为期21年（1998 - 2018年）的回顾性研究，以确定瓦尔格拉省（阿尔及利亚东南部）人间布鲁氏菌病的流行病学特征。
研究期间报告了1832例确诊的人间布鲁氏菌病病例，平均发病率约为每10万居民12.26例。发病率的年度分布呈上升趋势且波动较大；其值在每10万居民2.27例至24.96例之间。月度分布表明，2月中旬至7月发病率最高，4月达到峰值，每10万居民中有2.74例。人间布鲁氏菌病影响了所有市镇。边境市镇如本盖沙和乌姆蒂乌尔的发病率最高（分别为每居民89.76例和66.14例）。男性人群的发病率高于女性，分别为每10万居民14.63例和9.83例，且发病率随年龄增长而增加。65岁以上的个体风险最高，发病率为每10万居民22.32例。
除了加强人群中的预防措施外，消除动物中的布鲁氏菌病是保护人类免受感染的最有效方法。
