Most of the UK cases have been imported and assuming they go into hospital and get counted, unfortunately they create a bio hazard entering the country before they go sick enough to immobilise themselves. These are the cause of new unconnected cases in the UK (airport workers, health staff) but the doubling up scenario will not work in the UK as isolation (voluntary) and low risk pursuits have already started to be used by the population. The UK will virtually be in shutdown before a mandatory isolation occurs throwing your charts out. You need to take account of mentality e.g. Italians v British and plot that.
