Directly transmitted infections diseases: control by vaccination
Science (New York, N.Y.)
|February 26, 1982
Summary
Mathematical models help understand childhood disease patterns and guide vaccination strategies. These models provide criteria for disease eradication, applicable to measles and whooping cough control.
Area of Science:
- Epidemiology
- Mathematical Biology
- Public Health
Background:
- Mathematical models are crucial for understanding infectious disease dynamics.
- Age-specific incidence patterns of childhood diseases reveal insights into transmission before and after vaccination.
- Recurrent epidemic behavior in diseases can be linked to infection parameters.
Purpose of the Study:
- To utilize mathematical models to understand childhood disease dynamics.
- To establish criteria for disease eradication based on vaccination strategies.
- To analyze vaccination programs for measles and whooping cough in Britain.
Main Methods:
- Developing mathematical models for directly transmitted viral and bacterial infections.
- Relating interepidemic periods to infection parameters (latent period, infectious period, age of first infection).
- Calculating disease eradication criteria based on vaccination proportion and age-specific schedules.
Main Results:
- Model predictions align with observed age-specific incidence data for various childhood diseases.
- Interepidemic periods correlate with key infection characteristics.
- Specific vaccination levels and schedules are proposed for disease eradication.
Conclusions:
- Mathematical modeling provides a framework for understanding and controlling infectious diseases.
- Vaccination strategies can be optimized using model-derived eradication criteria.
- Analysis suggests necessary protection levels for eradicating measles and whooping cough in Britain.

Overview
01:20Infection
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

01:29Microorganisms in Medicine and Therapeutics
Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
01:21Vaccines
Vaccines are among the most effective tools in preventive medicine, designed to prepare the immune system to recognize and combat infectious agents. By introducing antigens—substances that the immune system identifies as foreign—vaccines stimulate an adaptive immune response that leads to immunological memory. This immunological memory enables the body to mount a faster and more effective response upon future exposures to the actual pathogen.Vaccines can be categorized based on the type of...
01:24Smallpox
Smallpox is a severe contagious disease caused by the Variola major virus, a double-stranded DNA member of the Poxviridae family.Variola major transmission occurs primarily via inhalation of virus-laden droplets or direct contact with infectious scabs. The incubation period averages approximately seven days, although it may range from 7 to 17 days depending on the inoculum and host factors.Clinically, the prodromal phase is marked by an abrupt onset of high fever, malaise, headache, and myalgia.
01:17Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
