I've been watching epidemiologists on TV and the point that they keep making is that the countries that have been successful in controlling the virus (Korea, Japan, New Zealand, Germany) have placed their emphasis on testing, contact tracing, and isolation of infected individuals along with ensuring those individuals have places to be isolated and daily checks on their well being and continued isolation. These are not cutting edge techniques, rather that they are epidemiology 101. In a previous century large sanitariums were built to treat TB which both isolated and treated an epidemic disease.
On a more personal note, I find it strange that people can be so cavalier about tens of thousands of preventable deaths. This also applies to the flu where there is a vaccine, but only about 1/2 actually get the shot.
