In the effort to contain infectious disease, contact tracing has always carried an implicit assumption: that partial information is better than none. New research from South Korean cities challenges that assumption with precision, revealing that tracing systems do not weaken gradually but collapse at specific, city-dependent thresholds — a finding that reframes epidemic control not as a universal protocol, but as a locally calibrated science.

Contact tracing effectiveness has city-specific thresholds (4% in Seoul, 10% in Busan) where systems break down, requiring tailored regional strategies based on population density and mobility patterns.

Households in high-density cities face stricter contact tracing requirements and faster epidemic spread if thresholds are exceeded, while lower-density areas have more tolerance for incomplete data. This affects healthcare costs, mobility restrictions, and insurance premiums during outbreaks.
Governments should implement differentiated contact tracing infrastructure based on regional population density rather than uniform national standards. This requires investment in localized digital surveillance systems, data collection protocols, and public health workforce training. May inform pandemic preparedness budgets and emergency response frameworks.
