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
This not true i don't know where you hear that they killed but i have talked to friend who are from China and confirmed me that no one where killed. Yes they have locked city and treat all who are infected and it's true that they're not telling how many people actually died. my friend told me in Wohan daily 100 people died so huge number of people died because of coronavirus even in news it's only 4000+
