Cytomegalovirus serological screening at the first antenatal visit: A tertiary‐centre audit of general practitioner practices and maternal seroprevalence.

Little is published on cytomegalovirus (CMV) serological screening at the first antenatal visit or the contemporary CMV seroprevalence rates among the Australian pregnant population. We performed a retrospective analysis of public hospital births in a major tertiary centre (n = 840) over a two month period. We found that 13.6% (95% confidence interval (CI) 11.4–16.1%) of women had been screened for CMV at their first antenatal visit with their general practitioner. Of these, 43.0% (95% CI 34.3–52.1%) were CMV seronegative and therefore susceptible to primary infection. Seronegative women were also more likely to have been born in an economically developed country, to live in a socio‐economically advantaged postcode and to be nulliparous. The information from this study may help guide future studies of congenital CMV risk reduction strategies. [ABSTRACT FROM AUTHOR]
