Could Intermittent Lockdown Save Us - And The Economy - From The Coronavirus?

Think of dieting. You can fast for 2 months and lose weight, but you will probably die. Even if you survive, you will quickly gain weight again. Similarly, a 2-month lockdown will suppress the coronavirus, but it will kill the economy. Lockdown will push hundreds of millions of people globally into unemployment and poverty. Many sectors of the economy will collapse. At the end of each lockdown, remaining patients will cause a resurge in the epidemic, forcing another lockdown.

This is the well-known yo-yo effect, with the number of coronavirus patients going up and down. At the same time, the global economy will be hit hard and hundreds of millions will go hungry. When the dust settles, more people will have died of hunger than of the coronavirus

Prof. Uri Alon and his graduate students Omer Karin and Yael Korem-Kohanim, together with senior engineer Boaz Dudovich of Applied Materials, suggest, based on an epidemiological model they developed, a policy that effectively suppresses the coronavirus and, at the same time, allows sustainable, albeit reduced, economic activity. The model is based on intermittent lockdown: 5 days of lockdown and 2 days of work every week. In this way, the virus replication number (the number of people infected by each infectious person) drops below one—the magic number that causes the epidemic to decline.

A 4-day work/10-day lockdown strategy is even better, allowing those infected at work to cease becoming infectious at home. Prof. Alon carefully suggests that, after several such cycles, the number of infected people will drop dramatically. The epidemic can thus be contained until sufficient testing, effective treatment, or a vaccine is developed, which will remove the need for a lockdown.

Intermittent lockdown may be the only viable option for countries that can’t deploy sufficient testing in a timely manner. It allows millions to work 2 days a week, sustaining key economic sectors. People will hold a 40% position instead of being completely unemployed—an economic and psychological game-changer.

Fixed workdays for everyone will allow workers and managers to plan ahead and stay productive. “Our main message,” says Prof. Alon, “is to open up the discussion on lockdown and point out that a well-designed, smart lockdown strategy can suppress the epidemic and sustain the economy.”
