We describe three Israeli children with fatal spotted fever. Clinical disease was characterized by irreversible shock, encephalopathy, renal failure, bleeding tendency, and death within 24 hours of admission. None of the patients had a history of tick bite, and no tache noire was noted. One child presented without rash, and the other two did not have antibodies to spotted-fever-group rickettsiae. The disease was confirmed by isolation of Rickettsia conorii from the patients' blood and tissues in cell cultures or from susceptible laboratory animals inoculated with human specimens. The present cases demonstrate the existence of a severe form of Israeli spotted fever in this population that resembles Rocky Mountain spotted fever. Because Israeli spotted fever may follow a quick, unpredictable, rapidly fatal clinical course, specific antimicrobial therapy should be promptly administered whenever the diagnosis is suspected.
