Neonatal herpes simplex virus (HSV) infection is an uncommon disease that rarely presents as sudden unexpected death of a previously healthy newborn. Clinical manifestations are variable; signs and symptoms may be subtle and nonspecific. Neonatal infection may present with mucocutaneous (skin, eye, and/or mouth), disseminated, or central nervous system disease. Morbidity and mortality are dependent upon disease presentation and treatment. The infection is most frequently transmitted during the peripartum period, although the majority of mothers have no known history of HSV infection at the time of delivery. Findings at autopsy include gastrointestinal or mucocutaneous ulcers, diffuse hepatic necrosis, adrenal necrosis, pneumonitis, and splenic necrosis. Characteristic intranuclear viral inclusions are identified on microscopic examination. Coinfection with bacterial organisms may contribute to death. Autopsy examination with appropriate ancillary studies, including cultures, is critical given that many infants lack cutaneous manifestations of disease and remain undiagnosed prior to death.

Neonatal herpes simplex virus (HSV) infection is a life-threatening infection with high morbidity and mortality rates. Neonatal herpes, most commonly due to HSV type 2, is a multi-system disease; however, initial pulmonary presentation is extremely unusual. We describe an infant presenting with progressive respiratory distress, which was the dominant clinical feature of HSV infection during the first days of life. Sepsis work-up and antibiotic treatment were immediately initiated; however, antiviral treatment was not given until the infant's death. HSV type 1 was isolated in nasopharyngeal and endotracheal aspirates. HSV pneumonia should be considered in a newborn with respiratory deterioration not compatible with common neonatal respiratory diseases.
