Let it get too big then abruptly clamp down, I predict.
My 2 pence for what I think might sustainably suppress Covid-19.
Work that does not require specialist equipment or face-to-face contact must be done from home. Make that law. No more managers demanding workers be in the office without good reason.
Similar rules for university education. If it's not a lab or similar, it should be done remotely. (Having students attend en masse was the most idiotic decision so far). Students should be encouraged to live at their home address where possible. Universities working together to make their facilities cross-available could facilitate this, for example a student at Durham who lives in Birmingham could do lab classes at Birmingham University.
Reinstate 2 metre social distancing in all indoor spaces, and cut out the loopholes (eg aeroplanes). The "1 metre plus" thing is a confusing joke and leads to a lot of people not even giving that distance. Retailers to reinstate number restrictions - that's gone out of the window and shops are often overcrowded again.
Restrictions on high-risk hospitality businesses re-imposed.
Good financial support for businesses forced to close and their employees. But with greater controls to prevent businesses that are not affected from, frankly, putting their snout in the trough as happened with the original furlough scheme.
(I wonder, why not have a general pause on debt and rent repayments? I suspect that for many business, if they didn't have to pay wages, rents, and debts then they could be "mothballed" for some time.)
Primary and secondary education to be looked at long and hard. Disruption to education will have impacts for decades so this should be a last resort.
