Although many studies on the COVID-19 epidemic in China have been published since the outbreak began, very few, if not none, have been useful to real-time epidemic control. None have proposed methods to identify areas at risk or to allocate (or reallocate) scarce health-care resources at a fine enough scale to effectively inform epidemic control on the ground. This situation is common to many infectious diseases, particularly epidemics, which have become increasingly multifactorial and dynamic as a result of rapid urbanisation, population growth and mobility, globalisation of travel and trade, and climate change.
