Viral infections in pregnant women are major causes of morbidity and mortality for both mother and fetus. Infections can transmit to the neonate transplacentally, perinatally, or postnatally. Some viral infections are more serious in pregnant than non-pregnant women due to the potential for vertical transmission to the fetus or infant. Pre-pregnancy or routine antenatal screening for existence of, or susceptibility to, some of these infections and appropriate management can prevent undesirable fetal or perinatal outcomes; screening should include rubella IgG, hepatitis B surface antigen, and serological tests for HIV antibody. The most of the tests suggested for the antenatal survelians differ through the populations and the time due to the changes of the epidemiology of the infections, the existence and the cost of the tests and the applications. If certain other vertically transmissible viral infections such as cytomegalovirus infection are suspected as a result of a positive antenatal test result, confirmatory tests for maternal and fetal infection are essential before intervention is considered. The antenatal survelians that not depents to accepted criterias or well prepared acting plannings can lead to unnecesseray problems and potensially hazardful developments.
