That's not really relevant. The cases are all still very far away from the WIV, which is itself far from anywhere the thread implicates eg residential areas.

I also suspect the thread is just flat wrong- the people most relevant to viral spread are NOT the ones who are only spending part of their day in the city. Its the people who live there and spend all their time there.

2/3rds of the population of Wuhan lives in the urban districts: https://en.wikipedia.org/wiki/Wuhan#Administrative_divisions

The people commuting in/out are a small minority. No model is perfect.
