 AB    A longitudinal study should be undertaken only when there is a clear
       reason to justify this and a reasonable chance of achieving the
       objectives. A multidisciplinary approach is often required, and
       continuity of staff and long-term collaboration with colleagues are
       important for their success. A longitudinal approach is required to
       estimate the prevalence of an infection in pregnancy and the rate of
       vertical transmission and to clarify the natural history in infected
       children. An example of cytomegalovirus infection is given; the
       parallels with HIV are obvious.
