Before revision:  The most successful containment policyreaches the lowest s factor, the characteristic time of the exponential growing doubling time in the arrested regime . South Korea, China, Italy and USA have reacheds= 5 , 6, 10, 18 respectively. The results clearly show that LFT containment policy has been able to reduce both the intensity and time width of the Covid-19 pandemic dome achieving both a low number of deaths and low economic losses .
After revision:  The most successful containment policyreaches the lowest s factor, the characteristic time of the exponential growing doubling time in the arrested regime . South Korea, China, Italy and USA have reacheds= 5 , was reached by LFT policy also the lowest number of deaths and the shorter time width of the epidemic dome was reached. The record for the largest number of deaths is correlated with the largest s factor in the near threshold regime where no containment measures were taken in time. LFT policy has been able to reduce both the intensity and time width of the Covid-19 pandemic dome achieving both a low number of deaths and low economic losses .
