Abstract The intergenerational τ has important theoretical and practical value to explore the law of virus transmission, but the probability distribution function is unknown. Therefore, this paper tries to infer the most probable form of the intergenerational interval distribution function by using the maximum entropy method, and analyzes the information of 4 986 cases of novel coronavirus from 20 countries in the world in detail, and estimates the mean and variance of the intergenerational interval of the virus on the basis of fully considering the diversity of samples. Then, based on this method, the global intergenerational interval distribution function of novel coronavirus was deduced and the basic reproduction number of China is calculated. The conclusion of this study is helpful for further objective analysis of the transmission characteristics of the virus, and provides important reference value for the formulation of regular epidemic prevention and control countermeasures and related research.
