In neonatal herpes, true is –
**Core Concept**
Neonatal herpes is a congenital infection caused by the herpes simplex virus (HSV), primarily transmitted from the mother to the neonate during delivery. This infection can lead to severe complications, including encephalitis, seizures, and death.
**Why the Correct Answer is Right**
Neonatal herpes is typically caused by HSV type 2 (HSV-2), although HSV-1 can also be involved. The virus enters the neonate's body through the birth canal, where it can infect the eyes, skin, and central nervous system. Infection can occur even if the mother has no symptoms of genital herpes, as the virus can be present in the cervix and vagina without causing noticeable symptoms. The virus then replicates and causes inflammation in the affected tissues, leading to the characteristic symptoms of neonatal herpes.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is not a characteristic of neonatal herpes. Neonatal herpes is not typically caused by a viral reactivation from a latent infection.
**Option B:** This option is incorrect because it is not a specific risk factor for neonatal herpes. While a history of recurrent genital herpes can increase the risk of transmission, it is not a direct cause of the infection.
**Option C:** This option is incorrect because it is not a treatment for neonatal herpes. Acyclovir is an antiviral medication that is used to treat HSV infections, but it is not a vaccine.
**Clinical Pearl / High-Yield Fact**
Neonatal herpes can be prevented with antiviral therapy during the third trimester of pregnancy in women with active genital herpes. This can reduce the risk of transmission to the neonate.
