To identify spatial and temporal, and spatial variation in temporal trends in clusters of tuberculosis (TB) among South American migrants residing in São Paulo municipality, SP, Brazil, between 2006 and 2013.
An ecological descriptive study was conducted using data obtained from official TB reports and the 2010 Brazilian demographic census. Clusters were identified using scan statistics and SaTScan software; those with P < 0.05 were considered statistically significant. Social and economic characteristics of residents within the clusters were investigated.
One high-risk spatial cluster (relative risk [RR] 4.46, P < 0.001) for TB was identified. Bolivian immigrants comprised the majority of immigrants residing in this area. One purely temporal high-risk cluster was identified between 2011 and 2013 (RR 1.55, P = 0.001). In one of the spatial variation in temporal trends clusters, the annual increase in TB incidence was 17.54% inside the cluster and 5.17% outside.
We found areas of high risk for TB among South American immigrants. These areas and those with increasing trends of TB incidence must be prioritised by TB control programmes.
识别巴西圣保罗市南美移民 2006 至 2013 年期间结核病（TB）聚集的时空和时空变化趋势中的空间聚集。
本研究采用来自官方结核病报告和 2010 年巴西人口普查的数据进行生态描述性研究。使用扫描统计和 SaTScan 软件识别聚集；具有 P<0.05 的被认为具有统计学意义。对聚集区内居民的社会经济特征进行了调查。
确定了一个高风险的空间聚集（相对风险 [RR] 4.46，P<0.001）。该地区的移民主要是玻利维亚移民。在 2011 年至 2013 年期间，确定了一个纯粹的时间高风险聚集（RR 1.55，P=0.001）。在时空变化趋势的聚集区中，聚集区内的结核病发病率年增长率为 17.54%，聚集区外为 5.17%。
我们发现了南美移民中结核病的高风险地区。这些地区和结核病发病率呈上升趋势的地区必须成为结核病控制计划的重点。
