Abstract

Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi, a Gram-negative intracellular organism transmitted
by Leptotrombidium mites, with wild rats serving as natural reservoirs. The disease is more common in the Tsutsugamushi
Triangle, often afflicting travelers and creating diagnostic challenges in clinical practice. We present the case of a diabetic
patient who acquired the infection while visiting an agricultural farm. Our discussion covers clinical manifestations,
diagnostic markers and treatment modalities, emphasizing the significance of early recognition and the benefits of prompt
treatment. The importance of searching for an eschar, a key physical sign, is underscored and potential serious outcomes
are discussed. Recent advances and preventive measures are also highlighted. This synthesis of research and clinical insights
aims to enhance global awareness, prompt diagnosis, and effective management of scrub typhus.
