 2019 NCOV infection has been spreading quickly since its emergence in Wuhan, China, and a deterministic compartmental model was developed to estimate the control reproduction number based on clinical progression, epidemiological status, and intervention measures. The estimations show that interventions such as intensive contact tracing and quarantine can effectively reduce transmission risk, with travel restriction having almost equivalent effects. The outbreak is expected to peak within two weeks under the most restrictive measures, with a significant decrease in infected individuals in seven days when travel restriction is implemented.
