Atypical SARS and Escherichia coli bacteremia

Area of Science:

• Infectious Diseases
• Public Health
• Critical Care Medicine

Background:

• Severe acute respiratory syndrome (SARS) is a highly contagious respiratory illness.
• Early diagnosis and effective infection control are crucial for managing SARS outbreaks.
• Atypical presentations of infectious diseases can pose diagnostic challenges.

Purpose of the Study:

• To describe a unique case of severe acute respiratory syndrome (SARS) where clinical symptoms were obscured by Escherichia coli bacteremia.
• To report the subsequent transmission of SARS to healthcare workers from this index patient.
• To underscore the importance of recognizing atypical SARS presentations and implementing robust infection control measures.

Main Methods:

• Case report detailing a patient with concurrent SARS and Escherichia coli bacteremia.
• Epidemiological investigation of SARS transmission within a healthcare setting.
• Clinical and diagnostic review of the index patient and affected healthcare workers.

Main Results:

• The patient's severe acute respiratory syndrome (SARS) presentation was initially masked by symptoms of Escherichia coli bacteremia.
• SARS subsequently developed in a cluster of healthcare workers who had contact with the index patient.
• Diagnosis was confirmed by the development of a chest infiltrate and a family member's hospitalization with acute respiratory failure.

Conclusions:

• Atypical presentations, such as SARS masked by bacteremia, can complicate diagnosis and lead to nosocomial transmission.
• Vigilance for severe acute respiratory syndrome (SARS) is necessary even when initial symptoms suggest other conditions.
• Enhanced infection control protocols are essential to prevent outbreaks in healthcare settings, particularly during atypical disease presentations.
