“…The most commonly used primary unit of analysis was more than one unit of spatial analysis; for example, counties; cities; provinces; districts; human and animal rabies cases; municipalities; administrative towns; cities; rivers; lakes; departments; and villages were applied in fteen articles or approximately 38% of the published studies [9], [21], [72], [80], [81], [89], [92], [27], [32], [36], [40], [42], [58], [62], [67]. Human and rabies cases were used as primary units in seven studies [14], [50], [52], [60], [63], [65], [77], and municipalities were used in four studies [54], [69], [74], [83]. Two studies [23][7] used the province as the unit of analysis.…”
