Over a period of 5 years (1993-97), 83 cases of murine typhus were identified and studied in the city of Chania, on the island of Crete. Of these cases, 4.8% were registered in 1993, 19.3% in 1994, 47.0% in 1995, 10.8% in 1996, and 18.1% in 1997. The greatest incidence of the disease occurred during the third trimester of the year. Direct contact with rats was noted in 45 (54.2%) of 83 patients. Two strains of Rickettsia typhi were isolated in cell cultures. The predominant clinical manifestations were: fever (100%), headache (88%), chills (86.7%), and rash (79.5%). In 4 of the patients (4.8%), the disease was complicated by acute renal failure, and in 4 other patients (4.8%), by pulmonary consolidations.
