Hemorrhagic smallpox

Last edited: 4/15/2026

Overview

Hemorrhagic smallpox, a severe and often fatal form of variola virus infection, is characterized by extensive skin hemorrhages, high fever, and significant internal bleeding 1. It represents a critical complication with high mortality rates compared to ordinary smallpox 1.

Diagnosis

  • Clinical presentation includes high fever, severe headache, back pain, and petechial or purpuric rash progressing to extensive hemorrhage 1.
  • Laboratory confirmation involves detecting variola virus DNA through PCR or viral isolation from vesicular fluid or blood 1.
  • Imaging may show hemorrhagic manifestations in affected organs, though not routinely diagnostic 1.

    • Management

  • First-line treatment: Supportive care including fluid resuscitation, pain management, and control of secondary infections 1.
  • Antiviral therapy: No specific antiviral treatment is widely recommended due to lack of clinical trial data; cidofovir has been explored in experimental settings but dosing specifics are not standardized 1.
  • Hemodynamic support: Monitoring and management of shock and coagulopathy are critical 1.
  • Blood transfusion: May be necessary for severe hemorrhagic complications 1.

    • Special Populations

  • Pregnancy: Data sparse; management focuses on supportive care with heightened vigilance for maternal and fetal complications 1.
  • Pediatrics: Children may present with more severe symptoms; supportive care tailored to age-specific needs is essential 1.
  • Elderly: Increased risk of complications; intensive supportive care and monitoring are crucial 1.
  • Comorbidities: Patients with underlying conditions require careful management of coexisting illnesses alongside smallpox treatment 1.

    • Key Recommendations

  • Prioritize supportive care including fluid management and infection control in all patients (Evidence: Strong 1).
  • Consider experimental antiviral therapies like cidofovir under strict clinical supervision, though standardized dosing remains undefined (Evidence: Moderate 1).
  • Tailor management strategies for special populations, emphasizing close monitoring and individualized supportive interventions (Evidence: Expert opinion 1).
