We retrospectively compared epidemiological, clinical, laboratory, and outcome characteristics of leptospirosis (n\u2009=\u200941) and rickettsial infections, including Q fever, scrub typhus, and murine typhus (QSM; n\u2009=\u2009103), in Kaohsiung City from 2013 to 2024. Leptospirosis occurred mainly during rainy and typhoon seasons and was associated with myalgia, gastrointestinal symptoms, jaundice, conjunctival suffusion, hepatic and renal dysfunction, leukocytosis, elevated C-reactive protein, and higher rates of acute kidney injury and shock. QSM occurred year-round, with eschar characteristic of scrub typhus, while prolonged activated partial thromboplastin time and relative bradycardia were more common in QSM. QSM generally showed a milder clinical course, particularly Q fever. Distinct clinical and seasonal patterns may facilitate early differentiation and risk stratification in endemic areas.<\/jats:p>","DOI":"10.1177\/00494755261454021","type":"journal-article","created":{"date-parts":[[2026,5,25]],"date-time":"2026-05-25T04:39:46Z","timestamp":1779683986000},"page":"675-680","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Differentiating
