In neonatal herpes, true is :

Neonatal herpes infection : It is commonly caused by HSV-2 (70% cases are caused by HSV - 2 and 30% caused by HSV - 1). Case fatality rate exceeds 60% in untreated neonatal herpes. The infection is acquired by passage through an infected genital tract at birth. The greatest risk i.e. 50% transmission rate occurs with a primary infection in the mother at time of delivery (because the antibodies have not yet developed, there is more virus present and no antibody transfer). With recurrent herpes at term, the transmission rate is only 8% or less. Neonatal infections present on the 6th day postpartum. There are three major categories. Localized skin, eye and mouth infection. CNS infection. Dissenminated infection. The hallmark of neonatal HSV infection - the vesicular, ulcerative skin lesions occur in only 30 - 43% children. If left untreated the virus dissenmination can occur to internal organs which is the most serious complication of neonatal herpes.
