Most people self-medicate acute coughs, but persistent coughs require medical attention. The exact causes of persistent coughs after viral upper respiratory tract infections (URTIs) remain unknown, posing a treatment challenge.

Area of Science:

  • Pulmonology
  • Infectious Diseases
  • Clinical Medicine

Background:

  • Self-medication is common for acute cough, with medical consultation sought only for persistent coughs.
  • The mechanisms linking viral upper respiratory tract infections (URTIs) to acute cough are not fully understood, though viral effects on airway sensory nerves are implicated.
  • The reasons for developing a persistent cough after a viral URTI are unclear.

Purpose of the Study:

  • To explore the current understanding of cough etiology, particularly persistent cough following viral URTI.
  • To review known causes and management strategies for chronic cough.
  • To highlight challenges in developing effective cough treatments.

Main Methods:

  • Literature review focusing on cough mechanisms, URTI-associated cough, and chronic cough.

  • Analysis of established associations between chronic cough and conditions like asthma, gastrointestinal dysfunction, and rhinitis.
  • Consideration of less-explored roles of cough in suppurative lung disease and interstitial lung fibrosis.

    • Main Results:

    • While acute cough is often self-managed, persistent coughs following URTIs lack clear etiological explanations.
    • Chronic cough has identifiable causes and associated conditions, but management strategies lack universal agreement.
    • The impact of cough in specific lung diseases such as interstitial lung fibrosis is under-researched.

    Conclusions:

    • Effective treatment for persistent cough, especially post-viral URTI, remains a significant clinical challenge.
    • Further research is needed to elucidate the mechanisms behind persistent cough.
    • Collaborative efforts between clinicians, scientists, and industry are essential for advancing cough therapeutics.
