The Reconstruction and Prediction Algorithm of the Fractional TDD for the Local Outbreak of COVID-19

Understand

From late December, 2019, the novel Corona-Virus began to spread in the mainland of China.

• For predicting the trend of the Corona Virus spread, several time delay dynamic systems (TDD) are proposed.
• In this paper, we establish a novel fractional time delay dynamic system (FTDD) to describe the local outbreak of COVID-19.
• The fractional derivative is introduced to account for the sub-diffusion process of the confirmed and cured peoples growth.
