The outbreak occurred in September to November in 1988 and its peak occurrence was in October. 2. Mean age was 52 years old (18 to 69 years old) and peak incidence was in the 6th decade. 3. Major symptoms and abnormal signs are fever/chills (88%), myalgia (65%), headache (54%), nausea and vomiting (31%), and abdominal pain (27%). The eschar was detected on lower part of body in most of cases, and more frequently in male (M:F 100 vs 58%). 4. Patients were treated with tetracyclines (TC) and/or chlorampenicol (CM) and mean duration of defervescence from initiation of antibiotic therapy was 2.1days with TC and 2.5 days with CM. 5. Complications are 2 cases of meningitis and 1 case of shock, and all cases were recovered without any sequelae.
