That is also what I think. It is due to virus that is why they burned the money. On the other side, I think they will not burn the without considering all of the possible effects or problems that will arise. In that case, they will already make a countermeasure to it. This virus is truely a serious case and money is very prone to it. Maybe if they don't do that, they think that more lives will be in danger and the economy will continue to go to down.
