On May 4, the top academic journal"Nature" magazine published the research from scientific research team of China, Britain and the United States. The study found through modeling that the three major non-pharmaceutical interventions used in China not only curbed the development of the epidemic in China, but also won a time window for the world. The study pointed out that if the strong non-pharmaceutical intervention is not implemented, the number of paitients in China may increase by 67 times to more than 7 million people.

The above research comes from a number of research teams including the University of Southampton, Fudan University, Wuhan Center for Disease Control, Harvard University, and Johns Hopkins University.

The researchers used epidemiology andanonymous human activity data to establish a model framework which uses dailytravel networks to simulate outbreaks and intervention programs across China.

The study also found that finding andisolating cases early prevents more infections than restricting travel andreducing person-to-person contact. However, only when a variety ofnon-pharmaceutical interventions are applied in concert can the strongest andfastest curbing effect be achieved.
