Congenital infection with cytomegalovirus (CMV) is the main cause of sensorineural hearing loss and psychomotor impairment which can develop at birth or later in infant's life. Because of a lack of nation-wide serological screening for pregnant women and accepted antiviral therapy during pregnancy in a high seroprevalence rate population of Poland, we introduced the regional screening programme for CMV infection in neonates from the Poznan Province to diminish a risk of the symptomatic disease. The aims of the study were: (i) to determine the prevalence of specific anti-CMV antibodies in populations of pregnant women and newborns from the Poznan area, (ii) to increase the early postnatal detection of congenital CMV infections, and  (iii) to evaluate a risk of perinatal or early postnatal infections with CMV in newborns or infants born to seropositive mothers. Serological testing was performed in 4.192 live born neonates, using dried blood filter-paper specimens.
