THE Chinese have always had a fascination with walls, culminating in the Great Wall of China to keep invaders out. They soon realised that walls don’t stop things coming in.Now they have put up another set of walls around a number of cities, initially Wuhan, to stop the coronavirus from escaping but again, the walls failed.
The coronavirus has started to spread, and we see desperate attempts to stop that spread, but the emphasis must be on curing rather than just containing the problem. The modern world moves too fast for walls to work.
