The exit criteria have been defined by the WHO. https://www.npr.org/sections/goatsandsoda/2020/04/15/834021103/who-sets-6-conditions-for-ending-a-coronavirus-lockdown https://www.npr.org/sections/goatsandsoda/2020/04/15/8340211... Individual governments such as the UK have established less restrictive conditions. The key point is building massive capabilities to test and contact trace so any further outbreak can be contained. Otherwise we will be lurching from lockdown to lockdown. Just because the US Federal government is unable to define criteria, because they don’t want to increase the manufacturing of test kits for political reasons doesn’t mean every other government has no clue.
