To estimate the incidence of Guillain-Barré syndrome (GBS)
following Campylobacter jejuni
infection (CI) we studied three populations where outbreaks of CI had occurred
estimated 8000 cases. No case of GBS was detected in the 6 months following
the outbreaks in
the local populations. The point estimate for the risk of GBS following
CI estimated in this
study was 0 in 8000 (95% confidence interval 0–3).
