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, if we adopt the constraint on m0, the number of all other people one meets separately each at a time, to the range 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 .
