Amid the global pandemic on coronavirus disease 2019 (COVID19) , epidemiologists promote containment strategies to prevent community transmission.(1) Contact tracing of susceptible persons and extensive testing in South Korea demonstrated as an example of successful containment.(1) South Korea reported the first confirmed cases on January 20, 2020, and the instances spiked from February 20 to 29, 2020.(2,3) As of mid-March, 2020, such containment strategies helped flatten the curve of new confirmed cases. The network analysis has been widely studied in various infectious diseases such as Middle East Respiratory Syndrome (MERS), (4, 5) Several Acute Respiratory Syndrome (SARS),(6)(6,7) tuberculosis, (8, 9) and cholera.(10) Some COVID-19 studies have revealed evolving person-to-person transmission dynamics in China in a longitudinal view.	./cache/cord-263698-5w70yhvy.txt	./txt/cord-263698-5w70yhvy.txt
