Before revision:  For example, if 70\% of the general public wear masks and contact tracing is conducted at 60\% efficiency within a 4-day time frame, epidemic growth will be flattened in the hardest hit countries. Finally, we analyze the bell-shaped curves of epidemic evolution from various affected regions and point out the significance of a universal decay rate of -0.32/day in the final eradication of the disease .
After revision:  We also compare our model behaviour to pandemic evolution data from various affected regions and point out the significance of a universal decay rate of -0.32/day in the final eradication of the disease .
