Epidemic outbreak of Coxsackie virus meningitis. Note I. Clinico-epidemiological features
Virologie
|October 1, 1976
Abstract:
An epidemic outbreak of viral meningitis mainly caused by Coxsackie B3 virus is described. Characteristic of the outbreak was the involvment of a large number of infants under 1 year of age (about 1/4 of the total number of cases) and the elevated incidence of encephalitis symptoms, as compared with the meningitis outbreak caused by echovirus 4 in 1973.
Insights
A Coxsackie B3 virus outbreak caused viral meningitis, notably affecting infants under one year old. This epidemic also showed a higher rate of encephalitis symptoms compared to a previous echovirus 4 outbreak.
Area of Science:
- Virology
- Epidemiology
- Pediatrics
Background:
- Viral meningitis outbreaks pose significant public health challenges.
- Coxsackie B viruses are known etiological agents of meningitis.
- Previous outbreaks provide a baseline for comparison of disease characteristics.
Purpose of the Study:
- To describe an epidemic outbreak of viral meningitis.
- To identify the primary causative agent, Coxsackie B3 virus.
- To characterize the clinical presentation, focusing on infant involvement and encephalitis incidence.
Main Methods:
- Retrospective analysis of an epidemic outbreak.
- Identification of the causative viral agent.
- Comparison of epidemiological and clinical data with a historical outbreak.
Main Results:
- The outbreak was primarily caused by Coxsackie B3 virus.
- Infants under 1 year of age constituted approximately 25% of all cases.
- Encephalitis symptoms were observed at a higher incidence compared to a 1973 echovirus 4 outbreak.
Conclusions:
- Coxsackie B3 virus can cause significant viral meningitis epidemics.
- Young infants are a vulnerable population during such outbreaks.
- The clinical presentation, including encephalitis, may differ between viral meningitis outbreaks.
