I think so far the chinese way is the best, they have been isolating EVERY CITY since February and now after more than a month, viruses are all dead, either by themselves or by killing the human they infected, and contained in hospital. If western countries take this approach, it would also stop the virus in one month
So indirectly you are saying that we should lock down all the cities (as virus has been spread world wide) and kill all those who are infected. You should know that the percentage of people who can die because of this virus is only 2% and the rest can be recovered. Why not take precautionary measures and heal the persons rather then killing them. Europe will never take this approach of killing the mankind.
