You're grossly misinformed. The China outbreak was so strong initially because they had no idea what they were dealing with. The spread and infection is invisible for weeks. There are many people spreading Coronavirus as we speak without knowing a thing.

Korea, Iran and Italy all have major outbreaks which only revealed themselves this week, but likely began 2-3 weeks prior. Iran has clearly no idea how many cases are in its country, its numbers are 15 deaths and <100 cases. That's over 15% death rate. Makes no sense compared to all other reported number, their real total cases are likely over 1000.

The mortality rate in Italy is roughly the same as China. I think it is too early to make this claim. https://gisanddata.maps.arcgis.com/apps/opsdashboard/index.h...?

It's because 14 days incubation time. It will take 14 days until number start to pick up from the initial infection in new area.

It also depends if there is a space available hospital --- overflown hospitals (as in Wuhan) will make numbers grow much quicker.

There have been nearly 300 new cases in South Korea in the last day. Give it time buddy.
