Abstract
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 twomonth 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.
