[The epidemic process in mumps infection]
Abstract:
Manifestations of the epidemic process of a parotitis infection can be explained by the theory of the self regulation of parasitic systems. A characteristic feature of epidemic parotitis is the formation of epidemic foci in the absence of parotitis cases and without the penetration of the infective agent from the outside. The epidemic wave of parotitis infection decreases as the virulence of the infective agent attenuates due to its passage through persons gaining immunity in the course of the epidemic. The avirulent infective agent persists in the body of some immune carriers till a sufficient stratum of susceptible subjects accumulates in the chain of the agent circulation. The analysis points to the autonomous character of the epidemic process not only among the urban and rural population, but also among separate social and age groups of the population within one town or settlement. The findings evidence an independent formation of the epidemic variant of the infective agent in individual schools and preschool institutions.
Insights
Epidemic parotitis (mumps) can form independent outbreaks, even without external infection. The infectious agent may persist in immune carriers until enough susceptible individuals emerge.
Area of Science:
- Epidemiology
- Infectious Diseases
- Theoretical Biology
Background:
- Epidemic parotitis (mumps) exhibits complex transmission dynamics.
- Understanding the self-regulation of parasitic systems offers insights into infectious disease patterns.
Purpose of the Study:
- To explain the unique manifestations of epidemic parotitis using self-regulation theory.
- To investigate the autonomous nature of mumps epidemic processes in various populations.
Main Methods:
- Analysis of epidemic parotitis (mumps) case data.
- Application of the theory of self-regulation of parasitic systems.
- Examination of infectious agent behavior and population immunity dynamics.
Main Results:
- Mumps can form epidemic foci without external infection introduction.
- Infective agent virulence decreases with host immunity, yet avirulent forms persist in carriers.
- Epidemic processes demonstrate autonomy within urban/rural, social, and age groups, and even in schools.
Conclusions:
- The epidemic process of mumps is largely self-regulating.
- Independent epidemic variants of the infectious agent can emerge in isolated settings like schools.
