Inevitably governments will look at countries that appear to be doing better and identify what they are doing differently. Face masks on public transport and in shops, contact tracing and some form of control of people coming into your country are some of the obvious candidates. Some may be more useful and practical than others. Making these things voluntary is an option, but does not seem at the moment certain to have the best outcome. I am optimistic that more people have had the infection and will be shown to have some form of immunity. But until we know for sure doing nothing is unlikely to be the best plan.
