I think the pillars are core to the management of any infection that spreads with a respiratory mechanism. By that, I mean the way we implement those and the tools that are used, at times after vaccination, etc., are going to be different.
Surveillance, understanding where the virus is and how it's moving, and understanding the geolocation of different variants and what they look like all require the ability to test people frequently over time and to monitor borders, but not necessarily keep them closed. The tools we use in the toolbox are going to change, but I think the pillars remain the same and the goals remain the same.
