Pandemic Influenza Preparedness and Response Plan

Objectives

The plan establishes a national, phased framework to prepare for, prevent, contain and respond to pandemic influenza, with the overarching aim of minimising mortality, health-system strain, societal disruption and economic disturbance. It covers command and control, risk communication, surveillance, laboratory diagnosis, healthcare delivery, vaccines, antiviral medicines, quarantine, public health measures, education, research and post-pandemic recovery.[1][2][3]

• Strengthen preparedness before a pandemic by stockpiling antiviral medicines and personal protective equipment, developing domestic pandemic-vaccine production, improving infection control, conducting exercises and maintaining continuity of essential services.[4]
• Align actions with the World Health Organization six-phase pandemic framework and national disaster phases of Concern, Caution, Alert and Severe, escalating preparedness or response according to domestic and overseas risk.[5][6][7]
• Prevent or delay virus importation and transmission through traveller screening, quarantine, isolation, contact management, rapid investigation, social distancing, school closures and infection-prevention behaviours where epidemiologically appropriate.[8][9][10]
• Protect healthcare capacity by ensuring timely triage, isolation, treatment, home care for mild cases, surge planning, workforce protection and allocation of scarce hospital beds, intensive-care capacity and respirators.[11][12][13]
• Prioritise vaccination and antiviral access for healthcare workers, first responders, essential-service personnel, high-risk groups and other groups selected according to pandemic epidemiology and available supply.[14][15][16]
• Use surveillance and modelling to identify novel viruses, monitor spread and severity, estimate demand for outpatient care, hospitalisation and deaths, and guide preparedness policy and medical-resource planning.[17][18][19]
• Support public understanding and adherence through timely, transparent and accurate risk communication for citizens, healthcare workers, agencies, media and other stakeholders.[20][21]

Implementation

Implementation relies on coordinated whole-of-government and whole-of-society action, activated and adapted by pandemic phase. The Ministry of Health and Welfare leads the health response, supported by the Korea Centers for Disease Control and Prevention, national crisis-management bodies, other ministries, local authorities, healthcare providers, laboratories, professional organisations, essential-service operators and international partners.[22][3][23]

• Operate governance through the Minister of Health and Welfare’s crisis assessment and emergency-alert authority, with alerts disseminated through the National Infectious Disease Control System; use the National Security Council, Central Safety Management Committee and Central Disaster and Safety Countermeasures Headquarters for cross-government coordination.[22][20]
• Convene the Influenza Pandemic Advisory Committee and technical immunisation bodies to advise on vaccine and antiviral priorities, public health measures and healthcare-service decisions, with government-wide decisions referred to the Central Safety Management Committee where consensus is required.[20][14]
• Maintain a central situation room, 24-hour emergency contacts, hotlines and information-sharing systems linking central government, local infectious-disease headquarters, rapid-response teams, quarantine stations, healthcare facilities and international organisations.[24][25]
• Deliver surveillance through the Korea Influenza Surveillance Scheme, laboratory networks, school absenteeism monitoring, emergency-room syndromic surveillance, sentinel facilities and international information exchange. Weekly reporting is required from 600 participating facilities and daily reporting from 100 institutions within the clinical surveillance scheme.[19]
• Use laboratories and Public Health and Environment Research Institutes to collect, test, confirm and characterise influenza specimens, refer unresolved or positive samples to the Korea Centers for Disease Control and Prevention, and share isolates through World Health Organization collaborating networks.[26][27]
• Deploy Rapid Response Teams during the alert period and early pandemic stages to verify suspected cases, conduct epidemiological investigations, collect specimens, manage patients and contacts, maintain investigation records and report promptly to national authorities.[9][28][29]
• Organise healthcare delivery through designated treatment hospitals, isolation facilities, admission triage, hospital emergency response committees, infection-control protocols, staff training, cohorting and home-care arrangements when patient volumes or staffing constraints require it.[12][30][31]
• Manage vaccine delivery through domestic production development, procurement contracts, multiple suppliers, recipient identification and vaccination registers, while monitoring adverse reactions and revising priority groups as epidemiological evidence develops.[32][15]
• Pre-position and distribute oseltamivir to regional and local Public Health Centers and designated treatment hospitals before relevant pandemic phases, aiming to enable treatment within 48 hours of symptom onset; record recipients and monitor resistance and adverse effects.[16]
• Conduct regular tabletop and field exercises, involving national and local health bodies, government agencies and experts, to test decision-making, inter-agency coordination, healthcare readiness, regulations, budgets and resource management.[2]
• Review and revise the plan, response guidance, laws and regulations as knowledge develops, exercises expose gaps or pandemic characteristics change.[4][33]

Operational monitoring includes phase classification, case and contact reporting, influenza-like illness rates, hospitalisations, deaths, laboratory findings, vaccine safety, antiviral resistance, healthcare-worker illness and service availability. The plan provides several surveillance measures and reporting mechanisms, but does not specify a single comprehensive set of performance targets, independent audit arrangements or a dedicated budget and financing framework.[19][34][35][2]

Monitoring & Evaluation

The plan establishes a phased monitoring and response architecture for pandemic influenza, combining national disaster alerts, clinical and laboratory surveillance, outbreak modelling, reporting systems, operational reviews and exercises. It uses surveillance and impact estimates to guide escalation, resource decisions and adaptation of public health measures, although a unified performance-management framework with standard targets, audit arrangements and independent accountability is not specified.[6][25][2]

• Classify national risk through four National Security Council disaster phases, using World Health Organization phase announcements for overseas outbreaks and Influenza Advisory Committee advice for domestic outbreaks; apply the higher applicable overseas or domestic risk level.[7][17]
• Use outbreak location, human infection and transmission, cluster size and population-level spread to inform phase assignment and emergency escalation.[7][17]
• Estimate likely disease burden with FluAid modelling, including outpatient visits, hospitalisations, severe illness and deaths by age, risk group and region; treat results as planning estimates rather than precise predictions.[17][18]
• Apply a 30% gross attack-rate scenario and an eight-week first pandemic wave as principal assumptions; this scenario projects approximately 54,600 deaths, 235,600 hospitalisations and 8.84 million outpatient visits nationally.[36][37][18]
• Maintain clinical surveillance through the Korea Influenza Surveillance Scheme, with approximately 700 participating healthcare facilities, including weekly reports from 600 facilities and daily reports from 100 institutions.[19]
• Track influenza-like illness rates against a weekly surveillance outbreak threshold of 7.5 per 1,000, and supplement clinical surveillance through absenteeism monitoring in 70 schools and emergency-room syndromic surveillance in 125 healthcare facilities.[19]
• Conduct laboratory surveillance through specimen collection, virus isolation, molecular testing, confirmation, antigenic and genetic characterisation, and sharing of isolates through World Health Organization Collaborating Centres.[26]
• Report emergency-room syndromic surveillance and infection-specialist-network signals daily through web-based systems, while laboratories report influenza results online and rapid antigen-testing organisations submit monthly results.[38][26]
• Operate integrated pandemic information systems covering healthcare resources, response workers, vaccine and antiviral recipients, patient and mortality monitoring, hospital surge capacity, and epidemiological investigation data.[25]
• Enable daily, rapid reporting to a central situation room on patient and death numbers, critically ill patients, hospital surges and influenza fatalities.[25]
• Replace individual case reporting during Phase 6 with monitoring of pandemic impact, including daily hospitalisations, deaths and local incidence.[34]
• Monitor vaccine adverse reactions, vaccination coverage and second-dose needs through recipient registers, particularly where pandemic vaccines are deployed before complete safety and efficacy evidence is available.[39][32]
• Monitor antiviral resistance throughout phases 1 to 6, monitor adverse effects during Phase 6, and maintain recipient records for Tamiflu allocation.[16]
• Require immediate notification of suspected cases to Public Health Centres, verification and epidemiological investigation by Rapid Response Teams, and reassessment within 48 hours where clinically necessary.[40][41]
• Use contact follow-up, including active symptom checks on the second and fifth days after exposure in Phases 3 to 5, and assess contact-management effectiveness after the pandemic.[10]
• Maintain border surveillance through traveller questionnaires, thermal screening, reporting to the Korea Centers for Disease Control and Prevention, Epi-trace recording and follow-up by local public health authorities.[42]
• Monitor hospital infection control through early detection systems, daily patient logs, fever and respiratory-symptom recording, and staff symptom monitoring in isolation settings.[43][44]
• Assess preparedness through annual tabletop and field exercises involving approximately 300 participants, using findings to identify shortcomings in response guidance, budgets, regulations and resource management.[2]
• Review plans continuously to identify strengths, weaknesses and gaps, incorporate developing evidence, revise response arrangements and amend relevant laws or regulations where necessary.[4]

Formal quantitative performance indicators are limited to specified surveillance thresholds, clinical criteria, reporting frequencies and modelling outputs. The plan does not specify a single reporting timetable across all functions, a standard evaluation methodology, independent audit procedures, accountability sanctions or a designated body responsible for system-wide performance assurance.[19][25][2]

Costing & Financing

The plan identifies substantial resource needs and recognises that pandemic influenza could generate high direct healthcare costs and major indirect socio-economic disruption. It promotes advance investment in surveillance, laboratory capacity, healthcare surge arrangements, vaccines, antivirals, infection control and continuity of essential services, but does not provide a consolidated budget, funding strategy or quantified financing gap.[4][45][23]

• Stockpile antiviral medicines, personal protective equipment, diagnostic reagents and other essential supplies, and establish secure systems for their storage, transport, distribution and priority-based administration.[4][46][8]
• Develop domestic pandemic vaccine production capacity, secure supplies through procurement contracts and multiple suppliers, and maintain a prepandemic H5N1 vaccine stockpile for first responders.[39][32]
• Plan healthcare surge capacity through designated treatment hospitals, isolation beds, additional staffing, critical-care capacity, respirators, blood supplies, medicines and home-care arrangements.[11][12][30]
• Provide for existing capacity of 516 designated beds at 38 hospitals, alongside plans for 80 negative-pressure beds and 320 general isolation beds over four years.[12]
• Use pandemic impact estimates to approximate requirements for healthcare workers, medical supplies and hospital beds, while recognising that estimates are intended for preparedness planning rather than precise forecasting.[17][47]
• Assess the costs and benefits of antiviral stockpiling against expected pandemic impact and prioritised benefits; avoid seasonal prophylaxis because it is characterised as costly.[46][8]
• Recognise potential economic effects of school and kindergarten closures, including increased childcare burdens and disruption to economic activity, and incorporate mitigation into planning.[48]
• Maintain essential transport, communications, electricity, water and public-security services during a pandemic to reduce societal and economic disruption.[4]
• Use exercises and research to identify issues in budgets, regulations and resource management, including isolation capacity, additional beds, intensive-care capacity and antiviral stockpiles.[2][49]

Explicit economic assumptions are limited. Impact modelling assumes a 30% gross attack rate and an eight-week first pandemic period, while high-risk group assumptions are 4% for people aged 0 to 18 years, 11% for those aged 19 to 64 years and 37% for people aged 65 years or over.[17]

No monetary programme costs, budget appropriations, funding sources, financing mechanisms, unit costs, resource-mobilisation targets or funding gaps are specified. Vaccination is characterised as the most cost-effective preventive measure during a pandemic, but no monetary estimate is provided.[39][32]
