Honestly - it's a lot easier to do that when you know the people in charge have had a plan, clearly communicate that plan and provide information as it changes. We knew 2 weeks after the first loosening that May 1st and May 15th were the next two target dates (2 weeks between each change to see the numbers over the virus incubation cycle) and then everyone is able to focus and it really helped with compliance with regulations. "Let's keep numbers down so we can proceed to the next step ... checking the official case numbers from the Health Ministry every day is our only sports now. The Chancellor and the Health Minister give clear, concise briefings without tons of theater, they set the example by wearing masks and maintaining distancing standards, etc. You earn buy in from the top.
Also, TEST TEST TEST TEST FUCKING TEST PEOPLE. At the start of March, Austria had already tested 235 people per million. The USA had tested 1 person per million. The very early testing (and it's continued - we've now tested more than 32,000 people per million) and access to testing allowed for much better early detection and limitation of the community spread. You can get tested with a quick result test at the airport (arriving or leaving). You can get tested by mobile units that come to your house so you don't go to the hospital. You can get tested randomly if selected for health ministry surveys to see the spread of the infection asymptomatically. Testing fucking works.
As an example of how well Austria seems to have identified and limited cases with vigorous testing,
today the results from a random nationwide survey done by the health ministry last week were released. 1,432 people randomly selected by their social insurance numbers were tested. Exactly 1 of them was positive with COVID-19. The community spread, for now, has been beaten back down.
The entire idea of restrictions and lockdowns was to be able to return society to normal as fast as possible. The only way to do that is to vigorously test, trace and kill off the exponential growth and community spread of the virus.
It looks funny, but our "new normal" seems to be here:
