Plan Nacional De Preparación Para Una Pandemia De Influenza

Objectives

Chile’s national influenza pandemic preparedness plan aims to reduce mortality, morbidity, social disruption and economic impact from a new, readily transmissible influenza subtype, while maintaining a flexible response capable of adapting to an unpredictable pandemic and evolving World Health Organization guidance.[1][2][3]It applies the World Health Organization’s four-period framework of interpandemic, pandemic alert, pandemic and post-pandemic periods, with phased objectives spanning preparedness, containment, mitigation, recovery and future readiness.[4][5]

• Strengthen preparedness at global, regional, national and local levels during the interpandemic period, including routine surveillance, vaccination, animal-health measures and advance planning for medicines and vaccines.[4][5]
• Minimise the risk of animal-to-human transmission and protect people exposed to potentially infected animals, particularly poultry workers and their families.[6]
• Ensure early detection, notification and response to human cases, supported by epidemiological and laboratory surveillance, outbreak investigation and control.[7][8]
• Contain or delay the spread of a virus during alert phases, including through case detection, contact follow-up, isolation, traveller measures, infection prevention and targeted antiviral measures.[9][10][11]
• Minimise the impact of a pandemic in Phase 6 by maintaining healthcare capacity, applying public-health and community measures, using vaccines and antivirals, communicating risks and supporting emergency operations.[12][13]
• Assess the first pandemic wave, restore intensified surveillance between waves, update protocols and the plan, and prepare for subsequent waves and future pandemics.[14]

Implementation

Implementation combines phased public-health action with national leadership, regional delivery and intersectoral coordination. The National Commission for Response to Outbreaks and Health Emergencies, within the Ministry of Health, develops contingency plans, oversees their implementation or adaptation, and provides technical advice; it includes political, technical and executive structures.[3]During higher alert and pandemic phases, an Emergency Committee led initially by the Minister of Health and, in Phase 6, coordinated by the Ministry of the Interior, directs mitigation plans with regional committees and operational working groups.[12][13]

• Coordinate preparedness through the Ministry of Health, Public Health Institute, Agricultural and Livestock Service, scientific societies, regional health authorities, municipalities, emergency authorities, central government bodies, armed and police forces, private clinics and other public and private health actors.[3][15]
• Maintain national and regional emergency commissions, with commissions in all 13 regions reporting through their Regional Health Authorities to the national commission during Phase 3.[8]
• Implement routine sentinel, active and passive surveillance; investigate influenza-like illness and unexplained respiratory outbreaks; strengthen laboratory diagnosis; and monitor circulating viruses, severe disease, mortality, travellers, contacts and illness among healthcare workers.[7][10][16]
• Refer positive influenza A samples to the Public Health Institute for viral isolation, antigenic typing and characterisation, while maintaining laboratory biosafety capacity and seeking access to World Health Organization reagents.[8][17][11]
• Prepare the healthcare network by developing referral and hospital-capacity plans, redirecting patient flows, converting beds, prioritising procedures, contracting or redistributing staff, and monitoring critical supplies, oxygen, medicines and personal protective equipment.[6][13]
• Apply infection prevention and control through hand hygiene, surface cleaning, personal protective equipment, case isolation, healthcare-worker monitoring and antiviral treatment where required.[13]
• Use antivirals for outbreak control, contacts where indicated and severe hospitalised cases, while maintaining, reviewing and replenishing antiviral stocks and monitoring antiviral resistance.[4][16][14]
• Plan pandemic-vaccine procurement through advance contracts and arrangements with the World Health Organization and manufacturers, then deploy vaccination according to vaccine availability and prioritised groups.[4][9][6]
• Deliver risk communication through designated national and regional spokespersons, daily press briefings, public information lines, an updated pandemic website and tailored advice for the public, professionals and groups at risk.[16]
• Implement proportionate community measures, including hygiene promotion, travel advice, restrictions on movement to risk locations, possible school closures, limits on mass or non-essential work activities, and voluntary or compulsory confinement of symptomatic people where necessary.[9][16]
• Mobilise budgetary and logistical support to procure and distribute medicines, supplies and equipment nationally, distribute resources to regions and healthcare facilities, and execute extraordinary pandemic-response resources according to Emergency Committee priorities.[15][18][14]
• Report the epidemiological situation regularly to national authorities, the surveillance network, the public and international organisations, including daily national and regional reporting during pandemic response.[2][12][16]
• Conduct exercises to test and correct plans, reassess preparedness against the evolving scenario, evaluate the effectiveness of control measures with the World Health Organization, and document lessons learnt after pandemic waves.[6][17][14]

Monitoring & Evaluation

The plan establishes a phased surveillance, reporting and review system spanning preparedness, alert, pandemic and post-pandemic periods. It relies on epidemiological and laboratory surveillance, rapid detection and notification, outbreak investigation, public communication and periodic reassessment of response measures.[4][9][5]

• Maintain active, passive, sentinel and laboratory surveillance of influenza-like illness, pneumonia, severe respiratory disease, respiratory morbidity and mortality, circulating viruses, geographical spread, and animal influenza.[7][6][8][10][17][16]
• Strengthen early detection, notification and investigation of suspected cases, unexplained acute respiratory outbreaks, informal reports, travellers from affected areas, contacts and exposed poultry workers and their families.[2][6][8][10][11]
• Refer positive influenza A or respiratory-virus samples to the Institute of Public Health, the national reference laboratory, for viral isolation, antigenic typing and characterisation; maintain laboratory biosafety capacity and obtain reagents through the World Health Organisation.[8][17][11][12][16]
• Monitor vital statistics, daily outpatient and emergency attendances, bed occupancy and availability, deaths, healthcare-worker illness, medicines, personal protective equipment, antibiotics, antivirals and oxygen, with reporting to Regional Health Authorities.[8][13]
• Provide periodic information to the public, reports to national authorities and international organisations, regular national and international situation reports, and real-time communication of the epidemiological situation to authorities and the surveillance network.[2][12][18][16]
• Use national and regional spokespersons, daily press briefings, an updated pandemic website and tailored messages for the public, professionals and at-risk groups to communicate risk and response measures.[16]
• Conduct pandemic exercises to test and correct the plan, reassess preparedness against the current scenario, and evaluate the effectiveness of control measures with the World Health Organisation.[6][17][11]
• Assess, after the first pandemic wave, epidemiological, operational, economic, resource-use, psychological and healthcare-worker impacts; document actions, lessons learnt and recommendations; update protocols, algorithms and the preparedness plan for later waves and future pandemics.[9][14]

Governance supports accountability through the National Commission for Response to Outbreaks and Health Emergencies, regional commissions and, during the pandemic, an Emergency Committee led initially by the Minister of Health and coordinated in Phase 6 by the Ministry of the Interior.[3][8][12][13]The supplied text does not specify a consolidated quantitative indicator framework, performance targets, a comprehensive reporting timetable, formal evaluation methodology or a formal public accountability mechanism beyond the surveillance, reporting, coordination and review arrangements described.[6][17][13]

Costing & Financing

Financial arrangements centre on mobilising extraordinary pandemic-response resources, budgetary support, procurement and logistics for medicines, supplies, vaccines, laboratory inputs and healthcare capacity.[15][18][14]No quantified budget, allocation, financing source, funding gap, unit cost or economic assumption is provided.[15][4][6][8][10][17][11][18][14]

• Assign budgetary support and mobilise resources to finance pandemic-control activities, with logistics responsible for procurement and national distribution of medicines and supplies through the Central National Supply Office.[15]
• Acquire and review antiviral stocks, arrange advance contracts or procurement mechanisms for pandemic vaccines, and review priority groups for vaccination according to vaccine availability.[4][9][6][8]
• Distribute resources to regions and healthcare establishments, including personal protective equipment, laboratory reagents, diagnostic kits, respiratory-support equipment, disinfectants and other infection-control supplies.[17][11][12]
• Execute extraordinary resources during the pandemic response according to Emergency Committee priorities, while monitoring requirements and replenishing medicines, supplies and equipment.[18][14]
• Plan for acquisition of vaccines containing the pandemic strain if available, replenishment of medicines and supplies, and resource needs for subsequent epidemic waves.[14]

Although reducing the pandemic’s economic impact is an overarching objective and post-wave review includes economic impacts and resource use, the supplied text provides no economic modelling assumptions or monetary estimates.[1][14]
