The number of confirmed Coronavirus Disease 2019 (COVID‑19) cases have been continuously increased since its first appearance in December 2019.[1] The disease becomes pandemic and WHO already declared public health emergency since 11th March 2020. An important public health manipulation for infection control is the systematic case registry. The registry data are important epidemiological information for disease management planning.
