[Measles in pregnancy: a review]

Abstract

Although measles is usually considered a benign viral disease of childhood, people may be affected whatever their age with severe pneumologic or neurologic consequences are more frequent before 5 years old and after 20 years old. The consequences of a congenital measles, defined as a newborn eruption within 10 days after birth, can be dramatic. The incidence of measles has significantly decreased since first vaccines were introduced in the late 1960s. In France, active immunization for measles is proposed since 1983. Since the beginning of 2008, France has been experiencing a measles outbreak with more than 17,000 notified cases. The current measles outbreak affects more particularly very young children and young adults and, among these, pregnant women. Measles during pregnancy may be severe mainly due to pneumonia. Measles is associated with a risk of miscarriage and prematurity, but congenital anomalies have not been described. If rash occurs near term, the consequences of congenital measles could be severe. Prevention of measles in pregnant women is based on improving immunization coverage, currently insufficient to eradicate virus circulation. The aim of this review is to state on the latest data concerning measles virus, give latest vaccine recommendations, and also to suggest management of measles contact or measles infection during pregnancy.
