the rapid quarantining of cities and the shutting down of the economy, appears to have worked and is now being held up as a model for the world. as the virus was allowed to spiral out of control in the province of hubei, it spread in smaller, but significant pockets to every province in china. this is the picture of a disaster. and it forced the government to act. and here's what happened. the official figures show that in hubei, although the numbers are still high, they are stabilising. and for the rest of china, even better news. the numbers kept low by those containment measures, and if we have a closer look, for more than a week now they have been falling. china's been so effective the world health organization says it's now safe to get the economy going again. welcome news on this farm.
