摘要
Corona virus disease 2019(COVID-19)is one of the worst infectious disease pandemics in the world since the 20th century.On 11 March 2020,the World Health Organization declared that the COVID-19 outbreak constituted a"global pandemic."Finally,it was not until May 2023 that the global emergency was declared over.Initially,non-drug interventions by countries,such as restricting inter-regional movement,reducing gatherings,and wearing masks,were effective in slowing the spread of COVID-19,while also decreasing influenza activity.
