Infection control for SARS in a tertiary paediatric centre in Hong Kong

Area of Science:

• Infectious Diseases
• Epidemiology
• Public Health

Background:

• Severe acute respiratory syndrome (SARS) emerged in 2003, rapidly spreading through hospitals and communities.
• Nosocomial transmission of SARS posed a significant threat to healthcare workers (HCWs) and patients.
• Effective infection control strategies were crucial for managing SARS outbreaks in healthcare settings.

Purpose of the Study:

• To evaluate the effectiveness of a triage policy and risk-stratified infection control measures.
• To assess the prevention of nosocomial SARS infection among pediatric HCWs.
• To analyze SARS prevention in a Hong Kong hospital during the 2003 outbreak.

Main Methods:

• Retrospective study of patients and HCWs in a pediatric unit.
• Stratification of wards into ultra high-risk, high-risk, and moderate-risk areas.
• Implementation of tailored infection control precautions based on risk stratification.
• Isolation of probable SARS cases in negative-pressure rooms.

Main Results:

• No HCWs developed clinical features suggestive of SARS.
• No nosocomial spread of SARS-associated coronavirus to other patients or visitors.
• All SARS patients were isolated in negative-pressure rooms, and HCWs followed risk-stratified precautions.

Conclusions:

• Stringent infection control precautions are vital for preventing SARS transmission.
• Effective triage and prompt isolation of potential SARS patients are key strategies.
• The implemented policy successfully protected HCWs and patients from nosocomial SARS infection.
