    24. Principles of Modern Quarantine A collective action for the common good predicated on aiding individuals infected or exposed to infectious agents while protecting others from the dangers of inadvertent exposure Public good Civil liberties SAFER • HEALTHIER • PEOPLE

    25. Purpose of Quarantine • Range of community containment strategies for infectious diseases • Applied to persons exposed but not ill, i.e., contacts (not cases) • Designed to meet two objectives • Facilitate early recognition of symptoms of a contagious disease, should they develop • Reduce risk of transmission before progression to disease has been recognized SAFER • HEALTHIER • PEOPLE

    26. Legal Authority • Legal right to take a particular action based on statute, regulation, or other legal precedent • Authority does not necessarily equal policy • Important tool, but not a substitute for • Resources • Planning • Communication SAFER • HEALTHIER • PEOPLE

    27. Key Questions before Decision to Quarantine • Is there public health and medical justification? • Infectious agent, communicability, risk of fatality • Are implementation and maintenance of quarantine feasible? • Define who is to be quarantined and for how long, and availability of resources • Do potential benefits of quarantine outweigh adverse consequences? • Determine health risks for those quarantined, consequences of quarantine disobedience, and effect on commerce JAMA, Dec 5,2001-vol 286, No 21:2711-2717 SAFER • HEALTHIER • PEOPLE

    28. Principles of Community Containment (1) Containment measures are appropriate when: • A person or group of people has been exposed to a highly dangerousand contagiousdisease • Exposed well persons are separated from illcases • Resources are available to implement and support interventions • Provide essential goods and services • Monitor health status (active vs. passive) • Provide immediate triage & medical care / isolation SAFER • HEALTHIER • PEOPLE

    29. Principles of Community Containment (2) Containment measures encompass a range of strategies: • “Snow days” or “shelter-in-place” • Suspension or restrictions on group assembly • Cancellation of public events • Closure of mass public transit • Closing of public places • Restriction or scaling back of nonessential travel • Cordon sanitaire SAFER • HEALTHIER • PEOPLE

    30. Principles of Community Containment (3) Containment measures are used in combination with other interventions • Enhanced disease surveillance and symptom monitoring • Rapid diagnosis and treatment for those who become ill • Primary and secondary preventive interventions, including vaccination or prophylactic antibiotics, PPE SAFER • HEALTHIER • PEOPLE

    31. Principles of Community Containment (4) Quarantined persons must be among the first to receive all available disease- preventing interventions • Vaccination (e.g., smallpox) • Antibiotics (e.g., plague) • Early, rapid diagnostic testing and symptom monitoring • Early treatment if symptoms appear SAFER • HEALTHIER • PEOPLE

    32. Principles of Community Containment (5) • Modern quarantine lasts only as long as necessary to ensure that quarantined persons do not become ill • Maximum quarantine duration related to the incubation period of disease • “Due process” rights for those subjected to quarantine restrictions SAFER • HEALTHIER • PEOPLE

    33. Principles of Community Containment (6) Modern quarantine does not have to be absolute to be effective • Even partial or “leaky” quarantine can reduce disease spread • Partial quarantine can be an effective supplement to vaccination SAFER • HEALTHIER • PEOPLE

    34. Principles of Community Containment (7) Containment measures are more likely to be applied to small numbers of exposed persons in focused settings: • Exposed persons on conveyance containing ill passenger(s) • Exposed persons in a theater where an intentional release has been announced • Close contact with a case SAFER • HEALTHIER • PEOPLE

    35. Principles of Community Containment (8) Implementation of containment measures requires: • A clear understanding of public health roles at local, state, and federal levels • Well-understood legal authorities at each level • Cooperation between public and private health-care sectors SAFER • HEALTHIER • PEOPLE

    36. Principles of Community Containment (9) Implementation of containment measures requires coordinated planning by many partners: • Public health practitioners • Health-care providers/facilities • Transportation authorities • Emergency response teams • Law enforcement • Security/Credentialing personnel SAFER • HEALTHIER • PEOPLE

    37. Principles of Community Containment (10) To achieve trust and cooperation, the public must be informed of: • The dangers of “quarantinable” infectious diseases before an outbreak occurs • The justifications for quarantine when outbreak is in progress • Anticipated duration and endpoints of control measures SAFER • HEALTHIER • PEOPLE

    38. Evaluating the Effectiveness of Quarantine Key Questions: • Was quarantine applied to the appropriate population? (efficiency) • Did use of quarantine limit progression of the outbreak? (efficacy) • Was the implementation of quarantine humane? SAFER • HEALTHIER • PEOPLE

    39. SAFER • HEALTHIER • PEOPLE

    40. Question 1: Elements of Response What were the elements of response to SARS containment? Was quarantine used alone? • Elements of SARS containment: • Case management • Contact management • Hospital/facility infection control • Community containment such as quarantine • Border responses SAFER • HEALTHIER • PEOPLE

    41. Question 2: Level of Response What were deciding factors for the levels of containment response? • Two levels of response: Basic and enhanced response, depending on: • Magnitude and scope of outbreak • Pattern of transmission • Resources available for response • Community cooperation and trust SAFER • HEALTHIER • PEOPLE

    42. Question 3: Case Management What is correct term for separation of cases? What were some basic methods of isolation (during minimal community transmission or fatality)? • Isolation • Home isolation • Suitable for providing adequate care • Adequate infection control measures possible • Hospital isolation if medically necessary SAFER • HEALTHIER • PEOPLE

    43. Question 4: Case Management What were some possible enhanced methods of isolation for cases (if greater community transmission occurred)? • Community-based facility isolation • Facility must meet patient care and infection control requirements SAFER • HEALTHIER • PEOPLE

    44. Question 5: Contact Management What is the correct term for separation of those who are contacts? What were some basic activities in contact management in the U.S? • Quarantine • Monitoring without activity restrictions • Assessment for signs and symptoms in well person(s) exposed to a contagious disease • Passive or active SAFER • HEALTHIER • PEOPLE

    45. Question 6: Contact Management • Describe some of the enhanced activities for restriction of movement of contacts in Canada and Asia • Home quarantine • Working quarantine • Facility-based quarantine • What was monitored daily in those under quarantine? • Clinical monitoring (Fever and respiratory symptoms) • Duration of quarantine? • Quarantine should not be longer than incubation period (for SARS, 10 days from exposure) • What resources need to be provided to those in quarantine? SAFER • HEALTHIER • PEOPLE

    46. Question 7: Community Containment measures Discuss some basic activities of community containment measures utilized around the world? • Public information and education • Promote “respiratory hygiene” and hand washing Describe some enhanced activities of community containment in Canada and Asia? • Cordon sanitaire • Widespread community quarantine • Measures to increase social distance SAFER • HEALTHIER • PEOPLE

    47. Question 8: Community Containment Measure What are ways to increase social distance? • Implement “Snow Day” restrictions • Close schools, day-care centers, etc. • Cancel large public gatherings (concerts, theaters) • Minimize other exposures (markets, churches, public transit) • Other measures • Distribution of surgical masks • Temperature screening in public venues • Scaling back transportation services SAFER • HEALTHIER • PEOPLE

    48. Question 9: Containment Strategy: Border and Travel Responses • Describe some basic activities towards border and travel response in the U.S? • Travel advisories and alerts • Distribution of health alert notices • Visual inspection of passengers from SARS-affected areas • Responding to ill passengers • Enhanced activities would have included…? • Pre-departure and arrival screening • Quarantine of travelers from areas with SARS • Restriction of nonessential travel SAFER • HEALTHIER • PEOPLE
