Establishment and utilization of infectious disease big data

COVID-19 Big Data (K-COV-N: KDCA COVID-19 NHIS COHORT)

COVID-19 Big Data (K-COV-N) safely combines domestic COVID-19 data and health data to support researchers and policymakers.

COVID-19 Big Data is currently being opened through the National Health Insurance Service’s big data open platform (nhiss.nhis.or.kr) since April 2022.
When private researchers apply for access, the data is provided to them in the form of a customized research database after undergoing a data provision review by the Korea Disease Control and Prevention Agency and the National Health Insurance Service.
Periodic presentations of research outcomes, such as big data utilization symposiums, are held to share research achievements with the public.
