Insights
Mumps meningoencephalitis predominantly affects boys aged 5-9 years, with most cases occurring in the last quarter of the year. This epidemiological analysis highlights key demographic and seasonal patterns of the disease in children.
Area of Science:
- Pediatrics
- Epidemiology
- Virology
Background:
- Mumps virus can cause meningoencephalitis, a serious inflammation of the brain and its membranes.
- Understanding the epidemiological distribution of mumps meningoencephalitis is crucial for public health interventions.
Purpose of the Study:
- To analyze the distribution of mumps meningoencephalitis in children based on sex, age, and seasonal factors.
Main Methods:
- Retrospective analysis of epidemiological data from 37 children diagnosed with mumps meningoencephalitis.
- Data collected included patient demographics, age, sex, and the time of year of diagnosis.
Main Results:
- The study identified a male predominance in affected children.
- The most affected age group was between 5 and 9 years old.
- A higher incidence of cases was observed during the last quarter of the year.
Conclusions:
- Mumps meningoencephalitis in children exhibits distinct epidemiological patterns.
- Male children between 5 and 9 years are at higher risk.
- Seasonal surveillance, particularly in the fourth quarter, is important for identifying and managing outbreaks.
Abstract:
The aim of this study was to analyse distribution of meningoencephalitis caused by mumps virus in children related to sex, age and seasonal influences. Thirty seven children were evaluated, ages ranging from 2 to 14 years. They were seen at Emergency Unit of Faculdade de Medicina do Triângulo Mineiro and at Hospital da Criança, in Uberaba-MG, Brazil, from March 1st 1991 to February 1st 1993 and they were hospitalized for about 5 days. Through a protocol findings were studied during hospitalization and clinical course stressing epidemiology, symptomatology, cerebrospinal fluid studies, electroencephalogram and cortical function analysis. Only epidemiological data were considered in the present study. Data analysis revealed male predominance, at a range from 5 to 9 years and great number of occurrences at the last quarter of the year.
