Understanding Neonatal Herpes: Causes and Risks

Understanding neonatal herpes is crucial for healthcare providers and parents alike, given its severe implications for newborns.

Causes of Neonatal Herpes

Neonatal herpes is primarily caused by the herpes simplex virus (HSV), which has two types: HSV-1 and HSV-2. While HSV-1 is commonly associated with oral infections, HSV-2 is typically linked to genital infections. Both types, however, can lead to neonatal herpes if the virus is transmitted to the infant during childbirth. This transmission occurs when a mother with an active herpes infection delivers the baby vaginally. Notably, the risk is higher if the mother acquires the herpes infection for the first time late in pregnancy.

Transmission of Neonatal Herpes

The transmission of neonatal herpes predominantly occurs during the birthing process. The virus can be present in the birth canal, and an infant can contract it while passing through. Less commonly, HSV can be transmitted in utero (congenital herpes) or postnatally, primarily through close contact with a person who has an active herpes infection.

Treatment Options

Treatment of neonatal herpes primarily involves antiviral medications, such as acyclovir, which can significantly reduce morbidity and mortality if administered promptly. The treatment duration and approach may vary depending on the severity and location of the infection. In cases involving severe organ involvement, intravenous antiviral therapy is often warranted.

Complications and Risks

Neonatal herpes can lead to severe complications if left untreated. These may include encephalitis, which is inflammation of the brain, and disseminated infection affecting multiple organs. Both conditions are life-threatening and require immediate medical intervention. Long-term complications may also arise, such as developmental delays or neurological deficits.

Preventive Measures

Preventing neonatal herpes primarily involves managing maternal herpes infections during pregnancy. Pregnant women with known HSV infections are often monitored closely, and antiviral therapy may be recommended in the later stages of pregnancy to reduce viral shedding. In cases of active genital herpes lesions at the time of labour, a cesarean delivery is typically advised to prevent neonatal transmission.

Understanding the complexity of neonatal herpes underscores the importance of early intervention and preventive strategies. By recognizing the causes, transmission pathways, and symptoms, healthcare providers can better manage and mitigate the risks associated with this condition, ensuring the health and safety of the newborn.
