Neonatal herpes simplex, or simply neonatal herpes, is a herpes infection in a newborn baby, caused by the herpes simplex virus (HSV). It occurs mostly as a result of vertical transmission of the HSV from an affected mother to her baby. [ 2 ]
Herpes simplex virus (HSV), which commonly causes cold sores and painful genital blisters can cause congenital infection via direct contact with genital tract lesions during delivery. Neonatal HSV may be classified into three categories based on symptom presentation:
Herpes simplex viruses can affect areas of skin exposed to contact with an infected person. An example of this is herpetic whitlow, which is a herpes infection on the fingers; it was commonly found on dental surgeon's hands before the routine use of gloves when treating patients.
Neonatal herpes simplex is an HSV infection in an infant. It is a rare but serious condition, usually caused by vertical transmission of HSV-1 or -2 from mother to newborn. During immunodeficiency, herpes simplex can cause unusual lesions in the skin.
In many infections, the first symptom a person will have of their own infection is the horizontal transmission to a sexual partner or the vertical transmission of neonatal herpes to a newborn at term. Since most asymptomatic individuals are unaware of their infection, they are considered at high risk for spreading HSV.

Some vertically transmitted infections, such as toxoplasmosis and syphilis, can be effectively treated with antibiotics if the mother is diagnosed early in her pregnancy.
TORCH syndrome is a cluster of symptoms caused by congenital infection with toxoplasmosis, rubella, cytomegalovirus, herpes simplex, and other organisms including syphilis, parvovirus, and Varicella zoster. [1] Zika virus is considered the most recent member of TORCH infections. [2]
HCMV is one of the vertically transmitted infections that lead to congenital abnormalities. (Others are: toxoplasmosis, rubella and herpes simplex.) Congenital HCMV infection occurs when the mother has a primary infection during pregnancy. [33] [34] [35] Up to 5 of every 1,000 live births are infected.
