What causes viral infections in new infants?

A doctor has provided 1 answer

New agents: New babies are pretected to some degree from the types of viruses the mom developed immunity to in her lifetime. This immunity is transient & passes thru the placenta during pregnancy.It lasts for a few months in most infants.Premis don't get as much as full term babies. If mom never had & developed immunity to a virus, baby will be susceptable.
