“…Since reactivating women possess preexisting circulating antibody intrauterine infection of the fetus does not occur and the baby is born healthy and uninfected. Others have also found that 2-3% of pregnant women excrete cytomegalovirus in the urine and on the cervix without infecting the fetus (Hildebrandt et al, 1967;Krech et al, 1968;Feldman, 1969;McCracken et al, 1969;Foy et al, 1970), though higher figures have been obtained for some Far Eastern countries (Alexander, 1967;Levinsohn et al, 1969). Continuing excretion of virus after term, however, perhaps in the throat and milk, provides a source of early infection for the infant once he has lost his maternal antibodies (Alexander, 1967;Stern, 1968;Levinsohn et al, 1969;Numazaki et al, 1970;Walker and Tobin, 1970); so far as is known these early postnatal infections are essentially benign.…”
