The unique resource of data on the population of Rochester and Olmsted County, Minnesota, assured that essentially all cases with a diagnosis of Guillain-Barr6 syndrome could be identified. Our review of the medical records for the period 1935 through 1968 identified 29 such cases, providing an annual incidence rate of 1.6 per 100,000. No significant difference by sex was found. Time-trend analysis showed no change in rates over the 34 year period. There was no clear seasonal pattern or clustering of cases in time. Two of the 29 patients died from their illness; beyond this, survivorship calculations based on follow-up through 1970 showed n o significant deviation from that expected for a population of matched age and sex.
