From the moment when Boris Johnson announced that the country was moving from containment to ‘delay’ in handling coronavirus, the world’s biggest healthcare organisation has been on a war footing. What doctors like me have witnessed over the past days and weeks has been nothing short of extraordinary. Trusts in the NHS declared a ‘major incident’ on the evening of the announcement, and emergency plans swung into action within hours.

The generational effect of the corona-virus is cunning and baffling. By often being so mild in the young and healthy it turns people into heedless carriers. By often being so lethal in the old and sick, it makes carriers into potential executioners of friends and neighbours. The virus is very dangerous for people who have certain underlying illnesses, which is probably the main reason it is so serious for the elderly.

In announcing the most far-reaching restrictions on personal freedom in the history of our nation, Boris Johnson resolutely followed the scientific advice that he had been given. The advisers to the government seem calm and collected, with a solid consensus among them. In the face of a new viral threat, with numbers of cases surging daily, I’m not sure that any prime minister would have acted very differently. But I’d like to raise some perspectives that have hardly been aired in the past weeks, and which point to an interpretation of the figures rather different from that which the government is acting on.

Working from home has been on the rise for years. No one expected the latest surge to happen in the way it has, but now that we’re here, what can we learn about home-working from those who have already done it? The first rule — even when times are normal — is: make sure you stay at home. Victor Hugo resisted the temptation to go out by ordering his valet to hide all his clothes. The Greek statesman Demosthenes achieved the same result by shaving half of his head.
