在秘鲁阿雷基帕市，2015年3月检测到一只狂犬病犬，标志着狂犬病病毒在该地区重新传入；此后又发现了更多狂犬病犬只。在阿雷基帕，自由流浪狗的出现似乎更多地出现在干燥的水道中，这在该市很普遍。我们创建了一个地理信息系统(GIS)，其中包含在疫情爆发第一年检测到的狂犬病犬的位置以及水道的监测数据。我们使用蒙特卡罗模拟进行了空间分析，以确定检测到的狂犬病犬是否比预期的更接近水道。在暴发的第一年发现了30只狂犬病犬，它们在统计上与水道有关(到最近的水道的平均距离=334m；p值=0.027)。水道可能在自由流浪狗种群的生态中发挥作用，起到生态走廊的作用。景观生态学有助于理解这些城市结构对控制活动和传播持续性的影响。
In the city of Arequipa, Peru, a rabid dog was detected in March 2015, marking the reintroduction of the rabies virus in the area; more rabid dogs have been detected since then. The presence of free-roaming dogs in Arequipa seems to be higher in dry water channels, which are widespread in the city. We created a geographic information system (GIS) with surveillance data on the location of rabid dogs detected during the first year of the outbreak, as well as the water channels. We conducted a spatial analysis using Monte Carlo simulations to determine if detected rabid dogs were closer to the water channels than expected. Thirty rabid dogs were detected during the first year of the outbreak, and they were statistically associated with the water channels (average distance to closest water channel = 334 m; p-value = 0.027). Water channels might play a role in the ecology of free-roaming dog populations, functioning as ecological corridors. Landscape ecology could assist in understanding the impact of these urban structures on control activities and the persistence of transmission.
