Now that western countries are getting caught up with testing protocols (South Korea has been in the forefront of proactive testing and their mortality rate is barely 0.5%), you'll see a lot more cases, yet the same amount of deaths, significantly dropping the mortality rate to a more seasonal flu-like level. Heck, when you exclude the nursing home in Washington (which has had documented problems in the past dealing with flu outbreaks there), the death rate here is 0.4%, and we have barely even started testing anyone.
