Corona virus can stay for a few hours on paper, currency notes, clothes, utensils etc and it is always advisable to avoid these items and even if one has touched them afterwards wash the hands. The problem is when the person supplying newspaper is all right there is not a problem but by chance he is infected then it would spread to so many. Prevention is always better than cure. Thats why newspaper is stopped in many areas. It applies to the milk packets, flowers, food items etc also. It is also a fact that everyone cannot be so vigilant and careful but let us try our best in these difficult times. Safety requires common sense and basic understanding, it does not require high academic degrees.
Knowledge is power.
