Summary

The 1985 Armero volcanic disaster survivors faced high rates of necrotizing fasciitis, including deadly mucormycosis. Early diagnosis and treatment are crucial for improving survival in mass casualty events.

Area of Science:

  • Infectious Diseases
  • Disaster Medicine
  • Clinical Microbiology

Background:

  • The 1985 Nevado del Ruiz volcanic eruption caused catastrophic loss of life and widespread injuries in Armero, Colombia.
  • Survivors transferred to Bogotá hospitals exhibited an unusually high incidence of necrotizing fasciitis.
  • This cohort represents a significant documented group of necrotizing fasciitis cases.

Purpose of the Study:

  • To review the clinical features of necrotizing fasciitis in survivors of the Armero disaster.
  • To specifically analyze cases of mucormycosis (a zygomycetic infection) within this patient group.
  • To highlight the importance of early diagnosis and treatment in mass casualty disaster scenarios.

Main Methods:

  • Retrospective review of 38 patients diagnosed with necrotizing fasciitis at four Bogotá hospitals.

  • Detailed analysis of clinical presentations, focusing on eight patients with confirmed mucormycosis.
  • Comparison of mortality rates between patients with and without mucormycosis.

    • Main Results:

    • Necrotizing fasciitis was prevalent among Armero disaster survivors treated in Bogotá.
    • Eight patients (21%) presented with mucormycosis, a severe and often fatal fungal infection.
    • Overall mortality for necrotizing fasciitis was 47.7%; for mucormycosis cases, it reached 80%.

    Conclusions:

    • Necrotizing fasciitis, particularly mucormycosis, posed a significant threat to survivors of the Armero volcanic disaster.
    • Prompt and aggressive surgical and microbiological interventions are vital for managing these severe infections.
    • Enhanced surveillance and diagnostic capabilities are essential for effective response to future mass casualty events.
