You should not worry about the current low approval ratings.

I'm sure it will easily go >50% once people see results coming - like field hospitals, hydroxychloroquine available to treat patients, etc.

Even below 50%, everyone seems to comply and follow up on the lockdown at the moment. I don't know about the precise situation in Europe, but I've been told France had to go to martial law because people were not complying with the voluntary lockdown.
