Study shows that by the end of February 2020 without non-pharmaceutical interventions (NPIs) in China– such as early detection, isolation of cases and social distancing – the number of infected people would have been 67 times larger than that which occurred. If NPIs could have been conducted one week, two weeks, or three weeks earlier in China, cases could have been reduced by 66%, 86%, and 95%, respectively, together with significantly reducing the number of affected areas. Improved disease detection, isolation of cases and social distancing are likely to a far greater positive impact on containment than travel restrictions, says the study.
