Abstract In this manuscript, we performed a scrutiny on hepatitis records collected in Brazil using statistical and computational tools aiming at analyzing the evolution of this disease during the period of 2007 and 2014. The study was performed in three phases. Initially, we used statistical tests to assess whether or not the notification cases were increasing. Then, we created a measure to quantify trends, without being affected by scale, thus allowing to compare the occurrence of hepatitis in different regions in Brazil. Finally, we used concept drift to detect the changing point when the notification behavior has changed over time. As a consequence of this study, public policies can be developed to deal with the increasing number of cases, specially by considering sexual transmissions.

应用概念漂移了解巴西肝炎的演变

摘要 在这份手稿中，我们使用统计和计算工具对巴西收集的肝炎记录进行了审查，旨在分析 2007 年和 2014 年期间这种疾病的演变。该研究分三个阶段进行。最初，我们使用统计测试来评估通知案例是否在增加。然后，我们创建了一种量化趋势的方法，不受规模影响，从而可以比较巴西不同地区的肝炎发生率。最后，当通知行为随时间发生变化时，我们使用概念漂移来检测变化点。作为这项研究的结果，可以制定公共政策来应对越来越多的病例，特别是通过考虑性传播。
