In 1977, 110 cases of stillbirth or neonatal death due to RhD haemolytic disease were registered in Britain; by 1992, this figure seemed to have dropped to nine cases.1 In this issue of the BMJ , however, Whitfield and colleagues show that this is a serious underestimation (p 1504).2 Extrapolation of their Scottish figures suggests that there are 50 deaths a year due to RhD haemolytic disease in Britain.
