Like hundreds of thousands of people across the world, the super-rich are preparing to self-isolate in the face of an escalation in the coronavirus crisis. But their plans extend far beyond stocking up on hand sanitizer and TV box-sets. The world’s richest people are chartering private jets to set off for holiday homes or specially prepared disaster bunkers in countries that, so far, appear to have avoided the worst of the Covid-19 outbreak. Many are understood to be taking personal doctors or nurses on their flights to treat them and their families in the event that they become infected. The wealthy are also besieging doctors in private clinics in Harley Street, London, and across the world, demanding private coronavirus tests.
