摘要：Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has caused hundreds of millions of in-fections and millions of deaths over past two years.Currently,many countries have still not been able to take the pandemic under control.In this review,we systemat-ically summarized what we have done to mitigate the COVID-19 pandemic,from the perspectives of virus trans-mission,public health control measures,to the develop-ment and vaccination of COVID-19 vaccines.As a virus most likely coming from bats,the SARS-CoV-2 may trans-mit among people via airborne,faecal-oral,vertical or foodborne routes.Our meta-analysis suggested that the Ro of COVID-19 was 2.9(95％CI:2.7-3.1),and the estimates in Africa and Europe could be higher.The median Rt could decrease by 23-96％following the nonpharmacological interventions,including lockdown,isolation,social dis-tance,and face mask,etc.Comprehensive intervention and lockdown were the most effective measures to control the pandemic.According to the pooled R0 in our meta-analysis,there should be at least 93.3％(95％CI:89.9-96.2％)people being vaccinated around the world.Limited amount of vaccines and the inequity issues in vaccine allocation call for more international cooperation to achieve the anti-epidemic goals and vaccination fairness.
