Insights
Two postal workers died from inhalational anthrax after exposure to contaminated mail. Early diagnosis of anthrax is challenging due to nonspecific symptoms, highlighting the need for rapid diagnostic tools.
Area of Science:
- Epidemiology
- Infectious Diseases
- Public Health
Background:
- Anthrax spores were mailed from New Jersey to Washington, DC in October 2001.
- The contaminated letter was processed at a major postal facility and opened in the Senate's Hart Office Building.
Observation:
- Five cases of inhalational anthrax occurred among postal workers between October 19-26, 2001.
- Two postal workers died from the infection.
- Patients presented with nonspecific prodromal illnesses, including gastrointestinal or flu-like symptoms.
Findings:
- Both deceased patients developed severe symptoms like dyspnea, chest pressure, and respiratory failure.
- Medical findings included leukocytosis, hemoconcentration, mediastinitis, and pulmonary infiltrates.
- The duration of illness from symptom onset to death was short (5-7 days), with rapid deterioration after hospitalization.
Implications:
- A high index of clinical suspicion is crucial for diagnosing inhalational anthrax, especially during nonspecific prodromal phases.
- Prompt communication of epidemiological data is vital for guiding clinical diagnosis.
- Development of rapid diagnostic assays for bioterrorism agents is needed to improve patient management and outcomes.
Abstract:
On October 9, 2001, a letter containing anthrax spores was mailed from New Jersey to Washington, DC. The letter was processed at a major postal facility in Washington, DC, and opened in the Senate's Hart Office Building on October 15. Between October 19 and October 26, there were 5 cases of inhalational anthrax among postal workers who were employed at that major facility or who handled bulk mail originating from that facility. The cases of 2 postal workers who died of inhalational anthrax are reported here. Both patients had nonspecific prodromal illnesses. One patient developed predominantly gastrointestinal symptoms, including nausea, vomiting, and abdominal pain. The other patient had a "flulike" illness associated with myalgias and malaise. Both patients ultimately developed dyspnea, retrosternal chest pressure, and respiratory failure requiring mechanical ventilation. Leukocytosis and hemoconcentration were noted in both cases prior to death. Both patients had evidence of mediastinitis and extensive pulmonary infiltrates late in their course of illness. The durations of illness were 7 days and 5 days from onset of symptoms to death; both patients died within 24 hours of hospitalization. Without a clinician's high index of suspicion, the diagnosis of inhalational anthrax is difficult during nonspecific prodromal illness. Clinicians have an urgent need for prompt communication of vital epidemiologic information that could focus their diagnostic evaluation. Rapid diagnostic assays to distinguish more common infectious processes from agents of bioterrorism also could improve management strategies.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
