The city of Hermosillo, in Northwest Mexico, has a higher incidence of tuberculosis (TB) than the national average. However, the intra-urban TB distribution, which could limit the effectiveness of preventive strategies and control, is unknown.
Using geographic information systems (GIS) and spatial analysis, we characterized the geographical distribution of TB by basic geostatistical area (BGA), and compared it with a social deprivation index. Univariate and bivariate techniques were used to detect risk areas.
Globally, TB in the city of Hermosillo is not spatially auto-correlated, but local clusters with high incidence and mortality rates were identified in the northwest, central-east and southwest sections of the city. BGAs with high social deprivation had an excess risk of TB.
GIS and spatial analysis are useful tools to detect high TB risk areas in the city of Hermosillo. Such areas may be vulnerable due to low socio-economic status. The study of small geographical areas in urban settings similar to Hermosillo could indicate the best course of action to be taken for TB prevention and control.
墨西哥西北部城市埃莫西约的结核病（TB）发病率高于全国平均水平。然而，城市内的 TB 分布情况尚不清楚，这可能会限制预防策略和控制的效果。
本研究使用地理信息系统（GIS）和空间分析方法，通过基本地理区域（BGA）对 TB 的地理分布进行特征描述，并将其与社会剥夺指数进行比较。使用单变量和双变量技术来检测风险区域。
总体而言，埃莫西约市的结核病在空间上没有自相关，但在城市的西北部、中东部和西南部发现了局部高发和高死亡率的聚集区。社会剥夺程度高的 BGA 具有 TB 发病的超额风险。
GIS 和空间分析是检测埃莫西约市 TB 高风险区域的有用工具。由于社会经济地位较低，这些区域可能较为脆弱。在与埃莫西约类似的城市环境中对小地理区域进行研究，可能有助于确定预防和控制 TB 的最佳行动方案。
