We used Breteau Indices to - retrospectively - predict dengue transmission. The presence of one house block (on average about 50 houses) with a Breteau Index >or=4 in a neighbourhood (a block plus the surrounding blocks in a radius of 100 m) predicted transmission at the latter level with 81.8% sensitivity and 73.3% specificity during the first month of the Havana 2001 dengue outbreak. This result corroborates the external validity of this threshold, at least in situations with low infestations levels.
我们使用布雷托指数（Breteau Indices）来-回顾性地-预测登革热传播。在哈瓦那 2001 年登革热疫情爆发的第一个月，一个街区（平均约 50 户）内存在布雷托指数（Breteau Index）>或=4 的房屋数量达到一户（一个街区加上半径 100 米范围内的周围街区），则后者的传播风险预测的灵敏度为 81.8%，特异性为 73.3%。这一结果证实了该阈值的外部有效性，至少在感染水平较低的情况下如此。
