I think all the preparation is very essential, especially when you have some information that there is an asymptomatic part of the epidemic. You have to have very good tools in your hands when it comes to testing and tracing mechanisms. This is critical to the entire process of prevention.
This is where I think Korea was able to come up with some innovative ways of testing and tracing, way back in February, by creating some partnerships between government and industry. We gave more leadership to industry so they could come up with an innovative way of testing and tracing.
