Five postulates for resolving outbreaks of infectious disease
1Virus Reference Division, Central Public Health Laboratory, London NW9 5HT, UK.
Abstract:
Outbreaks of infection challenge the surveillance of infectious disease, but they also offer opportunities to improve and refine it. An outbreak may be the first sign of an emerging pathogen or it may draw attention to a new risk group or route of infection. Postulates analogous to those used a century ago by Robert Koch to prove the microbial aetiology of infectious diseases can be employed to verify the existence of an outbreak, demonstrate its cause and pinpoint its origins. In doing this, high-resolution molecular finger printing of micro-organisms has now assumed a crucial role. Without formal analysis based on postulates, the existence, extent and source of outbreaks may be overlooked and public health interventions misapplied or lost.
Insights
Outbreaks reveal emerging infectious diseases and new risk factors. Molecular fingerprinting, akin to Koch
Area of Science:
- Epidemiology
- Infectious Disease Surveillance
- Molecular Microbiology
Background:
- Infectious disease outbreaks present significant challenges to public health surveillance systems.
- These outbreaks can signal the emergence of novel pathogens or highlight new transmission dynamics.
Purpose of the Study:
- To explore how infectious disease outbreaks serve as critical opportunities for enhancing surveillance.
- To demonstrate the utility of applying classical postulates for outbreak verification and source identification.
Main Methods:
- Utilizing postulates analogous to Robert Koch's for verifying outbreak existence and microbial etiology.
- Employing high-resolution molecular fingerprinting for precise identification of microbial sources.
Main Results:
- Molecular fingerprinting is crucial for confirming outbreak causality and tracing origins.
- Formal analysis based on postulates is essential for accurate outbreak assessment.
Conclusions:
- Outbreak investigations offer valuable insights for refining infectious disease surveillance.
- Adherence to established postulates and advanced molecular techniques ensures effective public health interventions.

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...
