Epidemiological and clinical features of leptospirosis in Israel.
The epidemiology and clinical features of 46 cases of human leptospirosis diagnosed in Israel between 1986 and 1999 were analysed. The median patient age was 37.5 years (range, 16-85 years), and the male/female ratio was 43/3. The most common serogroup found was Leptospira icterohaemorrhagiae. The disease was associated with jaundice in 71% of cases, acute renal failure in 62%, rhabdomyolysis in 52%, pancytopenia in 28%, respiratory failure in 14% and disseminated intravascular coagulation in 5%. Leptospirosis occurs sporadically throughout the year, peaking during the summer months. A shift occurred from predominantly agriculture-related serogroups in the 1970s to urban-related serogroups during the study period reported, with Leptospira icterohaemorrhagiae being the dominant serogroup.
