Abstract
During the summer of 1997, 2 confirmed and several suspected fatal cases of spotted fever (SF) occurred in previously healthy young adults in Israel. This unusual cluster of events stimulated the current study. The incidence of SF in Israel from 1971–98 was analyzed. Incidence increased until 1980, declined until 1994, and increased slightly from 1994–97. Incidence was higher during the summer, among children aged 0–9 years, and in rural settlements in central Israel. From 1971–1997, 31 deaths were reported, mostly in the elderly. The deaths that occurred in 1997 are a reminder that, despite the fact that morbidity due to SF is described mainly in children, SF can have a rapidly fatal outcome in healthy young adults. Thus, even during periods of low incidence, careful monitoring and high awareness for prompt diagnosis and treatment are needed.
