You seem to be pulling this out of your ar*e, since it is inconsistent with all U.S. reporting I’ve seen as well as second hand knowledge from acquaintances in China (in and out of Wuhan/Hubei), including medical professionals.
According to aforementioned sources, tests are administered for anyone who either show any symptom or are hospitalized for any reason. Some companies apparently also require testing — which is widely available now — before resuming work (reported by NYT[1], haven’t been able to confirm this myself). Recently a new cluster was discovered in Wuhan, and now they’re planning to test all 11 million residents.[1] I checked with two acquaintances in Wuhan (only got two, so unfortunately can’t provide a fuller picture), and this is apparently already underway, with one of them tested yesterday and one scheduled for tomorrow.
