Leptospirosis is considered an endemic disease in Buenos Aires province, Argentina, with human cases reported annually from rural and urban areas. The aim of the study was to describe the variables that influence the delay in the serological confirmation of leptospirosis in human cases (period 2006–2014) from Buenos Aires province. Sixty-four percent (64%) of cases could be confirmed by microscopic agglutination test (MAT) with the first sample. The time of confirmation of the human leptospirosis cases was on average 21 days from the onset of the first clinical signs, and varied depending on the distance of the different sanitary regions. The geographical distribution of the confirmed leptospirosis human cases, in addition to the high number of suspected cases and probable cases (which could not be confirmed by MAT), demonstrate that leptospirosis is endemic and underreported in Buenos Aires province, and that distance and lack of resources could be determinant factors of this situation.

钩端螺旋体病被认为是阿根廷布宜诺斯艾利斯省的一种地方病，每年都有来自农村和城市地区的人类病例报告。该研究的目的是描述影响布宜诺斯艾利斯省人类病例（2006-2014 年）钩端螺旋体病血清学确认延迟的变量。百分之六十四 (64%) 的病例可以通过显微镜凝集试验 (MAT) 与第一个样本进行确认。人类钩端螺旋体病确诊时间平均为首次出现临床症状后21天，并因卫生区域距离远近而异。已确诊的钩端螺旋体病人类病例的地理分布，除了疑似病例和可能病例数量较多（无法通过 MAT 确认），
