Closing china internally while allowing outgoing international flights, and somehow convincing WHO to pressure outside world away from closing borders was intentional.
> Closing china internally while allowing outgoing international flights
That didn't happen. When China shut down Wuhan, they shut down all transit, including international flights. The airport was completely closed. Even foreign nationals needed special permission and special chartered flights organized by their governments to leave.

The WHO has always been against closing borders during an epidemic. This wasn't a new recommendation. Just look up the WHO recommendations for every Public Health Emergency of International Concern. They discouraged travel bans in every single case.
