Abstract

BACKGROUND: In korea, tsutsugamushi disease is one of the common diseases which occurs in more than 40% among acute febrile diseases during Autumn. The diagnosis is confirmed with Rickettsia tsutsugamushi antibody, and is characterised by fever, chill, headache, myalgia, skin rash, escha and lymphadenopathy.
METHODS
We have conducted a survey on 16 clinically and serologically confirmed cases of Tsutsugamushi disease occurring during the period of October -November, 2000.
RESULTS
Of 16 cases,7 were males and 9 were females with an average age of 67.76. Most patients had fever, chill, headache, myalgia, sore throat, cojunctival injection, cough, abdominal, pain, nausea, vomiting, hematuria in order of frequency. The physical findings were eachar (81.257) and skin rash (62.77) . Serologically 7 cases (43.75%) of 16 cases were confirmed positively R.tsutsugamushi antibody. General hematologic findings were decreased platelet count (37.57) , increased or decreased WBC (31.25% and 25% each other) , and anemia (25%) , Test for liver function included elevated AST, ALT (68.76%) , alkaline phosphatase (62.6%) , hypoalbuminemia (12.6%) , and hyperbilirubinemia(6.25) . Urinalysis showed hematuria (50%) , proteinuria (50%) , and pyuria (12.67) . Doxyrcycline therapy decreased fever in 2.85 days and after 5-6 days patients were discharged with improvement of almost all symptoms.
CONCLUSION
Primary care physician in a community should always consider tsutsugamushi disease when he encounters patients with acute febrile disease in late Autumn and early winter and expect good prognosis with early diagnosis and treatment.
