No More Blanket Social Distancing Like COVID-19... Infectious Disease Response Now Divided Into Four Stages

KDCA Enacts "Infectious Disease Crisis Social Response Manual"

Assessment Also to Cover Impact on Education, Care, Economy, and Vulnerable Groups

During infectious disease outbreaks, a new standard has been established to determine the level of response by weighing both the effectiveness of preventive measures and their impact on daily life and the economy.

On August 18, the Korea Disease Control and Prevention Agency (KDCA) announced the enactment of the "Infectious Disease Crisis Social Response Manual" reflecting these principles. The manual was developed based on Korea's COVID-19 response experience; the World Health Organization (WHO)'s Public Health and Social Measures (PHSM) manual; domestic and international research; and the opinions of relevant ministries, local governments, and experts.

This manual emphasizes setting out principles and procedures to determine social response measures by considering both the risk level of an infectious disease and scientific evidence, as well as the current outbreak scenario and social equity. Social response measures are categorized as follows: ▲ individual protection, such as mask-wearing and hand hygiene; ▲ environmental measures, such as ventilation, air purification, surface cleaning, and disinfection; and ▲ social measures, such as managing the number of people and density, mobility-related actions, and the adjustment of activities and operations for events and facilities.

The response measures are divided into four stages: recommendation, strengthened recommendation, restriction, and prohibition. Depending on the characteristics of the infectious disease and the situation of the outbreak, the manual enables optimizing the intensity and application scope of social response measures by taking into account local, facility, and target-specific risks and conditions, along with protection and support plans.

Decisions on social response measures are made after comprehensive consideration of not only the mode of transmission, severity, and capacity of medical response, but also the expected effectiveness, the impact on daily life, economy, education, and care, equity for vulnerable populations, as well as feasibility and public acceptability. In cases where social contact and activities need to be significantly restricted, the manual recommends implementation only to the necessary extent, for the minimum period required, along with a simultaneous review of essential service maintenance and protection for vulnerable groups.

Following the implementation of measures, an evaluation will be conducted—based on data from relevant ministries and local governments—covering not only preventive effectiveness but also the impact on education, care, economic activity, and vulnerable populations, as well as the degree of adherence to and public acceptance of the measures. The findings will be reflected in future decisions on whether to maintain, reinforce, ease, or lift measures, and will inform amendments to the manual.

To achieve this, a system for routine cooperation and data sharing will be established among relevant ministries, local governments, and specialized agencies. Ongoing training and simulation exercises for staff in charge will also be conducted. The manual will be operated as a "living document," continuously revised and supplemented according to the latest domestic and international evidence and real-world crisis response experience as situations evolve.

Im Seungkwan, head of the Korea Disease Control and Prevention Agency, stated, "For the next infectious disease crisis, we will prepare in cooperation with relevant ministries and local governments in advance, so that a scientifically grounded, equitable, and effective social response can be achieved."
