yes but it didnt work
It did work. They got their cases under control. The cases have started to go back up when they stopped doing it.
The US never got it's cases under control. They were still increasing when the "lockdowns" (I use the quotes because there were never effective lockdowns in lots of places) started being lifted. This, coupled with the fact that no significant efforts were made to improve testing or contact tracing, is why America is now the epicenter of the virus in the world.
