Scrub typhus is a zoonotic rickettsial disease caused by the bacterium Orientia tsutsugamushi. The non-specificity of presentation, low index of suspicion and the poor availability of diagnostic tests often lead to delayed diagnosis and significant morbidity and mortality. Temperature, humidity, rainfall and Normalized Difference Vegetation Index (NDVI) on the spatio-temporal clustering of scrub typhus cases in children in three contiguous administrative districts in South India over 5 years were studied. A total of 419 children were diagnosed with scrub typhus during the study period. A surge of children with scrub typhus was noted when the NVDI ranged between 0.6 and 0.8 µm. Temperature, humidity and rainfall had a major role in the incidence of scrub typhus.

Scrub Typhus：印度南部的时空分析

恙虫病是由东方恙虫病菌引起的人畜共患立克次体病。表现的非特异性、怀疑指数低和诊断测试的可用性差常常导致诊断延迟和显着的发病率和死亡率。研究了 5 年内印度南部三个相邻行政区儿童恙虫病病例时空聚类的温度、湿度、降雨量和归一化植被指数 (NDVI)。在研究期间，共有 419 名儿童被诊断出患有恙虫病。当 NVDI 介于 0.6 和 0.8 µm 之间时，注意到患有恙虫病的儿童人数激增。温度、湿度和降雨对恙虫病的发病率有重要影响。
