We’re not going back to normalby Gideon Lichfield

Social distancing is here to stay for much more than a few weeks. It will upend our way of life, in some ways forever.To stop coronavirus we will need to radically change almost everything we do: how we work, exercise, socialize, shop, manage our health, educate our kids, take care of family members.
We all want things to go back to normal quickly. But what most of us have probably not yet realized—yet will soon—is that things won’t go back to normal after a few weeks, or even a few months. Some things never will.
It’s now widely agreed (even by Britain, finally) that every country needs to “flatten the curveâ€: impose social distancing to slow the spread of the virus so that the number of people sick at once doesn’t cause the health-care system to collapse, as it is threatening to do in Italy right now. That means the pandemic needs to last, at a low level, until either enough people have had Covid-19 to leave most immune (assuming immunity lasts for years, which we don’t know) or there’s a vaccine.
How long would that take, and how draconian do social restrictions need to be? Yesterday President Donald Trump, announcing new guidelines such as a 10-person limit on gatherings, said that “with several weeks of focused action, we can turn the corner and turn it quickly.†In China, six weeks of lockdown are beginning to ease now that new cases have fallen to a trickle.
But it won’t end there. As long as someone in the world has the virus, breakouts can and will keep recurring without stringent controls to contain them. In a report yesterday (pdf), researchers at Imperial College London proposed a way of doing this: impose more extreme social distancing measures every time admissions to intensive care units (ICUs) start to spike, and relax them each time admissions fall.
