A prospective study of rubella in 940 families in two cities of high and low clinical attack rates during the 1968–1969 Taiwan rubella epidemic showed the highest attack rates in school children under 10 years of age, all of whom were susceptible at the beginning of the epidemic. In the city with high attack rates, pre-school children had more rubella if they had an older sibling in school. The secondary clinical attack rate in families was over 60 per cent, whether or not school age children were present, suggesting near total infection when the disease was introduced into a family. Once infected, children 0–3 years had more inapparent disease than older children.
