Hello I have gone through your question and understand your concern. CMV is a treatable disease if regular check up and therapies are carried out, complications like neurological issues, hearing loss and other problems can be prevented. Babies who are infected in the womb usually show no symptoms of a CMV infection after they re born. In a few cases, there are symptoms at birth, which can include premature delivery, being small for gestational age, jaundice, enlarged liver and spleen, microcephaly (small head), and feeding difficulties. These babies are also at high risk for developing hearing, vision, neurological, and developmental problems. Typical blood picture shows loq to very low cell count, which may or may not need transfusiom pre-term babies have low immunity, fragile veins keeping in mind the risk benifit ratio tranfusion will be planned. So it is better to wait and act as treating doctor suggest. A mother who has a CMV infection shouldn t stop breastfeeding her baby, the benefits of breastfeeding are believed to outweigh the risks of passing CMV to the baby, who is unlikely to develop any symptoms if infected.
