Insights
Neonatal herpes simplex virus infection is fatal in 26% of cases. Despite early treatment with acyclovir, severe disease often develops rapidly in infants.
Area of Science:
- Neonatal Medicine
- Infectious Diseases
- Virology
Background:
- Herpes simplex virus (HSV) infection poses a significant threat to neonates.
- Neonatal HSV infection can lead to severe morbidity and mortality.
Purpose of the Study:
- To characterize the clinical course and outcomes of neonatal herpes simplex virus infection.
- To determine the case-fatality rate of neonatal HSV infection.
Main Methods:
- Retrospective study of 13 neonates with fatal HSV infection.
- Data collected from 2001 to 2011.
Main Results:
- A 26% case-fatality rate was observed.
- Fatal disease occurred within 48 hours of age in one-third of cases.
- Disseminated disease was the predominant presentation.
- Acyclovir therapy did not prevent fatal outcomes in most cases.
Conclusions:
- Neonatal herpes simplex virus infection has a high mortality rate.
- Rapidly progressive and disseminated disease is common.
- Current treatment strategies may be insufficient for severe neonatal HSV infections.
Abstract:
This retrospective study characterized the clinical course of 13 neonates who died with herpes simplex virus infection from 2001 to 2011, representing a 26% case-fatality rate. Fatal disease developed at ≤ 48 hours of age in one-third of infants, was mostly disseminated disease, and occurred despite early administration of high-dose acyclovir therapy.
