Pre‐conception care: an important yet underutilised preventive care strategy

To the Editor: Bateson and Black1 do a great service in encouraging clinicians to discuss pre‐conception care with women of reproductive age.1 However, in relation to infection prevention, one area not discussed was cytomegalovirus (CMV) infection, which is the most common infectious cause and the second most common aetiology of all causes of severe congenital malformations.2 Mother to child transmission of CMV can result in prematurity, stillbirth, cerebral palsy and neurodevelopmental delay and is the most common infectious cause of hearing loss.2 Discussions about CMV prevention should ideally commence before pregnancy, as maternal CMV infection in the first trimester poses the greatest risk of harm to the fetus if mother to child transmission occurs. Such discussions should continue throughout pregnancy, as secondary maternal infection with a different strain of CMV can also result in mother to child transmission of virus,2 although the risk per infectious event is lower.
