This review is the first to examine the history of scrub typhus in the context of notable historical events in Indonesia. Scrub typhus was first observed in 1902 and has since been documented through colonial and modern times. However, the available evidence is sparse. This lack of data is influenced by wider factors, including geopolitical climate and socio-economic factors. During the colonial era and World War II, research focused on economic and military interests. There were research gaps during the unstable period following independence in 1945. More research commenced only in the 1970s, mainly under the auspices of the Ministry of Health. Since 2000, there have been sporadic attempts to study scrub typhus on several major islands (Java, Sumatra, Sulawesi, Borneo, Bali). We found 51 relevant articles documenting the presence of the pathogen and its vectors, with only a single case confirmed with standard laboratory testing. This lack of data, combined with low awareness and diagnostic capacity, makes it difficult for policymakers to appreciate the impact of scrub typhus.
