Two competing epidemiological models currently guide and divide expert opinion on how best to respond to the novel coronavirus. The first, from Imperial College London, scared the U.S. and British governments into instituting strict social-distancing measures. It predicted that if left unchecked, COVID-19, the disease caused by the virus, could kill over half a million people in the United Kingdom and 2.2 million in the United States—not counting the many additional deaths caused by the collapse of each country’s health-care system.
The second model, developed by researchers at Oxford University, suggested that the virus had already infected as much as 40 percent of the British population but that most had shown mild or no symptoms. According to this model, COVID-19 would still cause many deaths, and it would still severely stress health-care systems. But because it predicted fewer critical cases to come, the Oxford model suggested that an indefinite lockdown might not be necessary.
