Abstract
An analysis of the transmission dynamics of rubella in Mexico based upon notified cases during 1983-1990 is presented. It is observed, for the first time, that the force of infection in the age-group of 15-44 years old and the average age of the infection at the national level show a slight increase simultaneously. The theoretical estimates of the interepidemic period coincide with the observed ones. The annual proportion of susceptible individuals is practically constant during 1983-1990. The intrinsic reproductive rate of rubella at national level and for the different age-groups is assessed. The annual estimates of Ro are small and they are practically unchanged for all age-groups, excepting the group of 15-44 years. The herd immunity of rubella for the different age-groups is evaluated and it is concluded that the best strategy for preventing congenital rubella in Mexico is to continue with the no vaccination policy against rubella. Nonetheless, the continuous monitoring of this policy is necessary.
