- Causes:
- Transmission occurs via close contact, often sexual, or through vertical transmission from mother to newborn during childbirth.
- Reactivation of latent virus in sensory nerve ganglia can lead to recurrent infections.
- Symptoms:
- Painful blisters or ulcers in the genital or oral area.
- Flu-like symptoms including fever and malaise.
- Neonatal HSV can cause severe systemic illness in newborns.
- Diagnosis:
- Clinical presentation with characteristic lesions.
- PCR testing or viral culture of lesion swabs.
- Serology can be used for detecting past infection.
- Management:
- Antiviral therapy with aciclovir or valaciclovir can shorten the duration of outbreaks and reduce the risk of transmission.
- In pregnant women with active lesions near term, caesarean section may be recommended to reduce the risk of neonatal transmission.
- Suppressive antiviral therapy may be considered for those with frequent recurrences.
- Complications:
- Neonatal HSV infection can cause severe neurological damage or death.
- Recurrence of genital herpes can lead to psychological distress and potential complications in pregnancy.
