The real mortality rate is undoubtedly much much lower. There are just untold numbers of people that have not been tested for several reasons and the truly infected number is much much higher. Even in China, during the height of it had people waiting in line all day to see if they had it and the healthcare workers triaged. So, not everyone was counted. Chinese residents stayed home unless they were really ill. So, that number is way way under-reported. South Korea is probably the model of what to do....Italy, not so much.
