“ a large number of infected people are asymptomatic or show only mild symptoms and will usually not be tested” No. WHO, China, Italy and South Korea have all looked and the hypothesised majority of asymptomatic cases doesn’t exist. China did 320k background tests in one province and had a 0.5% positive rate. There’s some asymptomatic cases, but no evidence suggests there are massive numbers. |

If they found a 0.5% positive rate on background tests there, that would suggest the real number of cases to be hundreds of thousands in that province alone.
You seem to be referring to this report: https://www.statnews.com/2020/02/25/new-data-from-china-butt...
That article suggests that the 320,000 tests were not a background test, but they tested "worried people [who] flooded fever clinics to be tested". Actual numbers across all population would hopefully be much less than 0.5%.
The article also states "The claim [that there's not huge transmission beyond what you can see clinically] was quickly challenged by an infectious diseases expert who serves on a committee that advises the WHO's health emergencies program.".
