The flu has a mortality rate of something like 0.1%, 200 our of 7000 is already 3%, 30x as deadly. Of course these aren't final numbers but the flu infects and afflicts vastly many more people than it kills.
Those 7000 infections are 7000 confirmed infections. Actual infections are going to be way higher than this (and hence, the mortality rate is going to be way lower) because of what was being discussed up-thread and in the article, i.e. infected people showing only minor symptoms and never getting admitted into a hospital where they would be tested for nCoV-2019.
