Is the common cold a clinical entity or a cultural concept?

Area of Science:

• Epidemiology
• Infectious Diseases
• Clinical Research Methodology

Background:

• The common cold is frequently studied as a defined clinical syndrome.
• Current diagnostic methods, including symptom scoring, are outdated and unsuitable for community diagnosis.
• Virological diagnosis is impractical due to numerous viruses and varied disease presentations.

Purpose of the Study:

• To evaluate the diagnostic approaches for the common cold in clinical research.
• To determine the most feasible method for diagnosing the common cold in research settings.

Main Methods:

• Analysis of existing diagnostic criteria for the common cold.
• Review of the limitations of symptom scoring systems and virological diagnosis.
• Consideration of self-diagnosis as an alternative research method.

Main Results:

• Traditional symptom scoring systems for diagnosing the common cold are based on outdated retrospective studies.
• Virological diagnosis of the common cold is not feasible in clinical practice.
• The common cold exhibits significant symptomatological variability.

Conclusions:

• The common cold should be considered a cultural concept rather than a distinct clinical entity.
• Self-diagnosis is a more reasonable approach for common cold research studies.
• Rethinking the definition and diagnosis of the common cold is necessary for accurate clinical research.
