A workable solution exists in choosing to temporarily change our behaviour.
Pause all unnecessary meeting. Compartmentalise into zones, restrict travel between them and grade them red, amber and green. Move activity outdoors where possible, and where not possible, ventilate as much as we can stand. Reorganise into closed community groups, and make larger groups of groups. Use group testing, eg. waste water testing. Use temporally segregated closed teams for essential activity. Take some windows out in each bus and train carriage. Etc, etc; I shouldn’t be the only one promoting ideas like this.
It’s doable. Some countries have eradicated it already. Scotland’s restrictions drove two strains extinct. Done right, it would take under two months, but half measures have already cost us a year. Let’s stamp the damn thing out before more mutations make it even worse.
