Serosurveys conducted at the end of the outbreak and 18 months later showed lower than expected disease prevalence rates (49%) and asymptomatic: symptomatic case ratios (1: 1) in the general population but significantly different prevalence rates (66%) and asymptomatic: symptomatic ratios (1: 2) in schoolchildren.
