Introduction
Singapore’s ability to respond to public health threats has improved significantly because of: • Its experience in managing the SARS
epidemic in 2003 and the Influenza A(H1N1) pandemic in 2009 and
• Its whole-of-government (WOG) approach in
preparing for a pandemic over the past 8 years.

Mission of CMG (Health)
• Manage all medical issues during a crisis E.g. civil emergency, mass casualties or disease outbreaks
• Provide emergency medical services
• Formulate response plans to deal with medical crises E.g. DORSCON framework
• Provide policy guidance and advice to responding agencies
![Page 9: Public Health Emergency Preparedness for Aviation Sector ...2 Scope • Introduction • National Crisis Response Framework Disease Outbreak Response System (DORS) • Changi Airport](https://reader033.vdocuments.mx/reader033/viewer/2022042315/5f0412a47e708231d40c2f34/html5/thumbnails/9.jpg)
Disease Outbreak Response System (DORS)
![Page 10: Public Health Emergency Preparedness for Aviation Sector ...2 Scope • Introduction • National Crisis Response Framework Disease Outbreak Response System (DORS) • Changi Airport](https://reader033.vdocuments.mx/reader033/viewer/2022042315/5f0412a47e708231d40c2f34/html5/thumbnails/10.jpg)
Disease Outbreak Response System (DORS) Colour-coded Graduated Response Framework • Based on risk of infection to individuals/community • Used in managing infectious disease threats
In a Whole-of-Government Approach
Establishes common understanding across Government agencies
• Allows graduated and defined responses • Provides recommendations and guidelines for medical
and non-medical measures • Facilitates decision-making & concurrent actions

DORS Conditions (DORSCON) • 5-colour DORSCON alert phases indicating increasing spread of a
highly virulent disease Each phase with control measures hardwired

DORSCON WHO PHASE DEFINITION AIM OF MEASURES
GREEN 0 GREEN 1 1 to 3
• No outbreak globally
• Outbreak (in single cases) in other countries
• Low risk of import
Maintain situational awareness Build capacity Step up surveillance Prevent import Raise public vigilance
YELLOW 4
• Elevated risk of import
• No local secondary transmission
Prevent further import Detect cases early Contain spread Protect essential services
ORANGE 5
• Local transmission confined
• Low risk of community transmission
Contain spread (break local transmission chain) Suppress and slow down spread Prevent export of cases Enhance public vigilance
12
DORS Conditions (DORSCON)
![Page 13: Public Health Emergency Preparedness for Aviation Sector ...2 Scope • Introduction • National Crisis Response Framework Disease Outbreak Response System (DORS) • Changi Airport](https://reader033.vdocuments.mx/reader033/viewer/2022042315/5f0412a47e708231d40c2f34/html5/thumbnails/13.jpg)
DORSCON WHO PHASE DEFINITION AIM OF MEASURES
RED 6
• High risk of acquiring disease from community
Gain control of community spread
Mitigate consequences of pandemic
Continue to prevent export of cases
Step up crisis communications
BLACK 6
• Local infection out of control
• Widespread community transmission
• Escalating morbidity & mortality rates
Medical & public health measures take precedence over social & economic considerations
Limit impact on community
Facilitate recovery of healthcare systems

DORS Conditions (DORSCON)

![Page 14: Public Health Emergency Preparedness for Aviation Sector ...2 Scope • Introduction • National Crisis Response Framework Disease Outbreak Response System (DORS) • Changi Airport](https://reader033.vdocuments.mx/reader033/viewer/2022042315/5f0412a47e708231d40c2f34/html5/thumbnails/14.jpg)
Lessons from 2009 H1N1 Pandemic Some limitations of DORS were noted: • Considered only the spread but not severity • No public communication component • DORSCON alert phases corresponded to WHO Pandemic
Alert Phases for Influenza and not reflective of local situation
![Page 15: Public Health Emergency Preparedness for Aviation Sector ...2 Scope • Introduction • National Crisis Response Framework Disease Outbreak Response System (DORS) • Changi Airport](https://reader033.vdocuments.mx/reader033/viewer/2022042315/5f0412a47e708231d40c2f34/html5/thumbnails/15.jpg)
Reviewing DORS Framework • Take into account the severity (virulence) of the infectious
disease, in addition to its spread
• DORSCON alert phases to be based on MOH’s risk assessment of the likely public health impact
• Provide clear guidance for agencies
• Balance clarity with flexibility in response
• Be adaptable and provide for gradation in the suite of measures to be taken
• Contain a public communications component
![Page 16: Public Health Emergency Preparedness for Aviation Sector ...2 Scope • Introduction • National Crisis Response Framework Disease Outbreak Response System (DORS) • Changi Airport](https://reader033.vdocuments.mx/reader033/viewer/2022042315/5f0412a47e708231d40c2f34/html5/thumbnails/16.jpg)

Border Health Response Measures
• A phased and gradual approach will be adopted to step up control measures in accordance with developing circumstances as guided by principle of risk management
• Implementation & subsequent stepping up of various border control measures will be aligned with defined triggers at various DORSCON alert levels with the aim to have early detection & prevention of possible importation of influenza case(s)
