The article comments on issues concerning the lack of medical screening in Great Britain. It is estimated that 40% of the decline in the prevalence rate of neural tube defects (NTD) in Britain was due to antenatal screening. However, despite the availability of a highly effective and simple method of prevention, women continue to have pregnancies with NTD, because screening is not enough. With this regard, immediate implementation of national fortification programs is recommended.
