  A mathematical model is proposed for quantitative description of the outbreak
of novel coronavirus COVID-19 in China. Although the model is relatively
simple, the comparison with the public data shows that an exact solution
solution of the model (with the correctly-specified parameters) leads to the
results, which are in good agreement with the measured data. Prediction of the
total number of the COVID-19 cases is discussed and an example is presented
using the measured data in Austria.
