Well most of it is still locked down, traffic is still only around 10% of normal traffic there this time of year.Its also just logic, if you weld everyone Indoors, everyone with the virus either died, or recovers and wasn't around anyone else to pass it on to.Im also assuming nobody is stupid enough to voluntarily enter Wuhan at the moment who doesn't live there, or have to be there for supply chains etc.The issue will be when Wuhan is fully open again, it will only take 1 or 2 people to enter with the virus to kick it all off again and infect those who managed to avoid It the first time around, while the rest should be ok because they developed immunity.But then the virus likely is a different strain every season like flu, so the ones who developed immunity to the first Wuhan strain, won't have immunity to the 2nd.
Natural selection favours milder strains of the disease.
The thing that gets very little attention is the fact that coronaviruses have been infecting humans for donkeys years. We just pass it off as a common cold now.
Covid-19 is just the birth off a new common cold virus. Again it's natural selection taking place as evident in the people we see it taking out. If this virus happened 200 years it would barely be a footnote in history, but mankind has become soft and this is the end result.
We will get a reset after this, albeit a small one, but it's better than nothing.
