Epidemiology of Guillain-Barré syndrome

From 1969 through 1972, a nationwide search for cases of Guillain-Barré syndrome (GBS) is Israel revealed 89 patients. The average annual age-adjusted incidence was 0.75 per 10(5) persons. Overall incidence of the syndrome was similar in Jewish groups of diverse ethnic backgrounds. Arabs had a lower overall incidence than Jews (0.46 per 10(5) persons), perhaps attributable to fewer Arabs at risk in older age groups. Peaks of incidence occurred among individuals over 60 and under 4 years of age when all cases were combined. No clear seasonal or geographic clustering of GBS was evident in Israel during the 4 years of this study. The incidence of GBS in the present study agrees with previous population-based estimates.
