[Epidemiology of measles and mumps. 2nd part: mumps (author's transl)]
Abstract:
Similar to measles, mumps morbidity is also seen to follow an undulating course with a 2--3 years rhythm as well as having an annual peak in the second quarter. The peak of the age specific morbidity, however, is found in the 7th--8th year of life and consequently part of the infections only appear later in adulthood. Most of the infections remain subclinical and only about 12% are recorded. Morality is about 1 : 100 000, meningitis occurs in about 1,5% of the infections and is benign in most cases. Encephalitis occurs in about 0,9% of cases and frequently leads to brain damage.
Insights
Mumps exhibits a cyclical pattern in morbidity, peaking annually in Q2 and every 2-3 years. While most infections are subclinical, complications like meningitis and encephalitis can occur, with encephalitis potentially causing brain damage.
Area of Science:
- Epidemiology
- Virology
- Public Health
Context:
- Mumps, a viral illness, presents with distinct epidemiological patterns.
- Understanding mumps' cyclical trends and age-specific incidence is crucial for public health interventions.
Purpose:
- To describe the epidemiological characteristics of mumps, including morbidity patterns, age distribution, and clinical outcomes.
- To analyze the incidence of complications such as meningitis and encephalitis.
Summary:
- Mumps morbidity follows a 2-3 year undulating course with an annual peak in the second quarter.
- The highest age-specific morbidity occurs in the 7th-8th year of life, with infections sometimes manifesting in adulthood.
- Approximately 12% of mumps infections are clinically recorded, with a mortality rate of 1:100,000.
- Meningitis affects about 1.5% of cases and is usually benign, while encephalitis occurs in 0.9% and can lead to neurological damage.
Impact:
- Provides insights into mumps' epidemiological dynamics to inform vaccination strategies and resource allocation.
- Highlights the potential for severe neurological complications, emphasizing the importance of disease prevention.
- Contributes to the understanding of subclinical infections and their role in disease transmission.
