And what happens if you're told to self-isolate but you feel a pressing need to load the family in the car and drive to a secluded cottage?
I think if someone is deemed high risk they should be tested even without symptoms. That seems fecking ridiculous when a lot more tests are available than March and April. Otherwise it is in people's interest to say they have symptoms anyway. Someone could repeatedly be asked to isolate either because they haven't had the virus or have already had it and been asymptomatic.
The tracers are supposedly going to check up on people but with those arriving from other countries having to be checked up on too this may be far too large a task.
