This report presents the observations on seasonality and neonatal tetanus (NNT) mortality from a cluster survey on NNT mortality conducted in Kano metropolis, Northern Nigeria. A two stage cluster sampling method was used for the survey. There were 2,623 live-births with 1778 (67%) occurring in the dry season (October-May). The NNT mortality rate was 20.6/1000 live-births. The magnitude of neonatal mortality and NNT mortality were 47.3 and 30.8 per 1000 live-births respectively for the wet season. These were much higher than the comparative figures for dry season. There was, however, no significant association between seasonality and NNT mortality since the same trend was observed for non-NNT deaths.
本报告展示了在尼日利亚北部卡诺市进行的关于新生儿破伤风（NNT）死亡率的整群调查中对季节性和NNT死亡率的观察结果。该调查采用了两阶段整群抽样方法。共有2623例活产，其中1778例（67%）发生在旱季（10月至次年5月）。NNT死亡率为每1000例活产20.6例。雨季新生儿死亡率和NNT死亡率分别为每1000例活产47.3例和30.8例。这些数字远高于旱季的对比数据。然而，由于非NNT死亡也呈现相同趋势，所以季节性与NNT死亡率之间没有显著关联。
