Since receiving unexplained pneumonia patients at the Jinyintan
Hospital in Wuhan, China in December 2019, the new coronavirus (COVID-19) has
rapidly spread in Wuhan, China and spread to the entire China and some neighboring
countries. We establish the dynamics model of infectious diseases and time series model
to predict the trend and short-term prediction of the transmission of COVID-19, which
will be conducive to the intervention and prevention of COVID-19 by departments at all
levels in mainland China and buy more time for clinical trials.
