Rubella susceptibility in Jamaican women, 1996

The 1995 rubella outbreak in Jamaica indicated a need to survey the susceptibility rate in Jamaican antenatal women at risk. In this 1996 study, 389 women in the reproductive age group were investigated for rubella antibodies. In the public sector urban group (A), rubella susceptibility was 20.2%, while in a private sector urban clinic (B) practising routine rubella surveillance and recommending postpartum immunization in seronegatives, the susceptibility rate was 13.8%. The latter rate was significantly lower than that in the rural group (C) (35.9%; p < 0.001). The overall susceptibility rate was 21.3%. Rubella susceptibility has improved overall in women of childbearing age compared with levels in the prevaccine year of 1968. A significant thrust in rubella prevention will still be required before the next rubella epidemic in order to reduce the risk of congenital rubella syndrome.
