According tomedia reports, the United States is facing a severe COVID-19 outbreak, since the outbreak, the country’s new crown confirmed more than 1.6 million people, and the death toll is close to 100,000. Researchers at Columbia University have produced a model showing what would happen if the blockade began a week in advance across the United States. Models suggest that about 36,000 new coronavirus deaths in the United States could have been prevented if the blockade had been activated early.
“We found a significant decrease in the number of underlying infections of neo-coronaviruses associated with maintaining social distance and other control measures in major metropolitan areas,” the researchers wrote. “Counterfactual simulations suggest that a large number of cases and deaths may be avoided if these same control measures are implemented only 1-2 weeks in advance. Specifically, they went on to say that, at the national level, 61.6 per cent of reported infection rates and 55 per cent of reported deaths could be avoided.
According to the researchers’ modeling, most new coronavirus deaths (83 percent) in the U.S. could be completely avoided if cities and states across the U.S. began blocking and restricting social contact on March 1 — about two weeks before the first Americans began to stay at home with the coronavirus.
Jeffrey Shaman, an epidemiologist at Columbia University and lead author of the research team, told the New York Times: “That little time, seizing it at that stage of growth, is a critical phase of reducing deaths.” “
By the time the “home order” began across the United States in March, about 28,000 people had been infected with the new coronavirus, researchers said. However, as of mid-March, only 99 confirmed cases were known in the United States, as of mid-March, because of the lack of testing and contact tracing in the United States at the time.
