An effective and feasible approach to prevention of primary cytomegalovirus infection in pregnancy

In the absence of a cytomegalovirus (CMV) vaccine, other strategies for prevention of primary infection in pregnancy should be considered. Behavioural interventions have been reported to significantly decrease seroconversion rate among seronegative pregnant women. We report here on a recently completed controlled study in which seronegative women at high risk of infection because of close contacts with children <36 months, were identified and informed about risky and protective behaviours. Informed women seroconverted at a significantly lower rate than non-informed women.
