Before revision:  Second, in the moderate constraints where the width ranges between 2 to 8, the constraints may temporarily seem to work for the reduction of infections in the early stage but it is just the delay of peaks i. e., the reduction may not mean the suppression of an expansion .
After revision:  Second, in the moderate constraints where the width ranges between 2 to 8, the constraints may temporarily seem to work for the reduction of infections in the early stage but it is just the delay of peaks . Based on these results, a policy is proposed here: for quickly suppressing the number of infections, restrict W to less than 4 if the constraint to make m0 at most 1 is too strict. If W is set to less than 4, setting m0 to 4 or less works for quick reduction of infections according to the result .
