A baby was born via vaginal delivery at 41 weeks’ gestation to a 25-year-old primigravid with no known history of genital herpes simplex virus (HSV). Both parents reported previous oral HSV but no active lesions. Maternal history revealed a childhood varicella zoster virus (VZV) infection. Antenatal VZV titres were consistent with immunity. Integrated prenatal screen testing was declined. Membranes ruptured 8 h before delivery, with one documented maternal fever of 38.5°C. No genital HSV lesions were observed at delivery.
