Summary
Neonatal herpes simplex virus (HSV) infections, though rare, pose serious risks. Early diagnosis and treatment with acyclovir are crucial for improving infant outcomes and reducing mortality from this significant neonatal pathogen.
Area of Science:
- Neonatal infections
- Virology
- Pediatric infectious diseases
Background:
- Herpes simplex viruses (HSV) are common pathogens with potential for vertical transmission, leading to severe neonatal morbidity and mortality.
- Neonatal HSV infection incidence varies, but is significantly higher (up to 50%) following primary maternal infection compared to recurrent infection (<3%).
- Infections are classified as skin, eye, and mouth (SEM), central nervous system (CNS) encephalitis, or disseminated disease, each with varying severity.
Purpose of the Study:
- To review the clinical presentation, diagnosis, treatment, and prognosis of neonatal herpes simplex virus infections.
- To emphasize the importance of clinical awareness and timely intervention in managing neonatal HSV.
- To provide guidance on recommended treatment protocols and supportive care for affected infants.
Main Methods:
- Review of clinical categorizations of neonatal HSV infections based on disease extent (SEM, CNS, disseminated).
- Discussion of diagnostic challenges, highlighting the need for high clinical suspicion.
- Outline of current treatment recommendations, including intravenous acyclovir, and supportive care measures.
Main Results:
- Caesarean section is recommended for mothers with active genital herpes lesions to reduce transmission risk.
- Early diagnosis and treatment are critical; delayed management significantly increases morbidity and mortality.
- Prognosis is directly related to disease extent, with disseminated infections having the worst outcomes, though SEM infections can also lead to poor developmental outcomes.
Conclusions:
- Neonatal HSV infections, while uncommon, are associated with substantial risks if not promptly identified and treated.
- High clinical suspicion, thorough infant examination, and appropriate investigations are essential for accurate diagnosis.
- Intravenous acyclovir remains the recommended treatment, and early therapy considerably improves the prognosis for affected neonates.
