The overall comparisons of habitats are given in (Table III). The habitats are arranged in order of extent of alterations by man, with the least disturbed at the top. The highest average blood isolation rates came from the least disturbed areas. The highest monthly maximal rickettsial isolation rates from blood and maximal prevalence rates of antibody per month were also obtained at Bukit Lanjan, the habitat least altered by activities of man. The lowest average blood isolation rate (6%) and the lowest monthly maximal rickettsial isolation and antibody prevalence rates were obtained at Bukit Mandol, the habitat most extensively and intensively altered by man. The intermediate habitats had intermediate rates. We caution anyone interpreting these observations, however, in terms of human disease, which seem to be associated with hyperendemic foci. Here we are not dealing with hyperendemicity from the standpoint of human disease, but present evidence of widespread endemicity from which hyperendemic foci may derive. Also, we have not yet identified the prevalent strains and do not know their infectivity to man.
栖息地的总体比较结果列于（表III）中。栖息地按照人类改变程度的顺序排列，最未受干扰的排在首位。平均血液分离率最高的来自受干扰最少的区域。在布吉兰樟（Bukit Lanjan），即受人类活动改变最少的栖息地，每月血液中最高的立克次体分离率以及每月抗体的最高流行率也同样被观察到。在布吉曼多尔（Bukit Mandol），即受人类活动最广泛且最强烈改变的栖息地，平均血液分离率最低（6%），每月立克次体的最高分离率和抗体流行率也最低。中间类型的栖息地则具有中间水平的比率。然而，我们提醒任何解读这些观察结果的人，就人类疾病而言，这些结果似乎与高度地方性病灶相关。在此，我们并非从人类疾病的角度来探讨高度地方性，而是呈现广泛地方性的证据，高度地方性病灶可能由此而来。此外，我们尚未确定流行菌株，也不清楚它们对人类的传染性。
