Two communities of Orang Asli (aborigines) in Peninsular Malaysia were observed for evidence of Rickettsia tsutsugamushi infection over periods of 1-8 mo. Sequential sera were examined for antibody by the indirect immunofluorescence test. The incidence of infection in the two self-selected populations in the two communities was calculated to be 3.9% per month and 3.2% per month.
在1至8个月的时间里，对马来西亚半岛的两个原住民（奥朗阿斯利人）群落进行了观察，以寻找恙虫病立克次体感染的证据。通过间接免疫荧光试验对连续采集的血清进行抗体检测。经计算，这两个群落中两个自行选定人群的感染率分别为每月3.9%和每月3.2%。
