 Since the emergence of the first cases in Wuhan, China, the novel coronavirus 2019 NCOV, infection has rapidly spread to other provinces and neighbouring countries. Estimating the basic reproduction number using mathematical modelling can help determine the potential and severity of an outbreak, as well as provide critical information for identifying the type of disease interventions and intensity. A deterministic compartmental model was developed based on the clinical progression of the disease, epidemiological status of the individuals, and intervention measures. The estimated values from likelihood and model analysis suggest that the control reproduction number could be as high as 6.47, 95% CI 5.71 to 7.23. Sensitivity analyses showed that intensive contact tracing followed by quarantine and isolation or travel restrictions can significantly reduce the control reproduction number and transmission risk. Increasing quarantine by 100,000 baseline value would have similar effects to travel restrictions. It is important to assess how expensive, resource intensive measures implemented by the Chinese government can contribute to the prevention and control of the 2019 NCO.
