Spain( 15.46/100 000), Switzerland(15.44/100 000) and Italy ( 15.30/100 000)ranked top three in the incidence rate of COVID-19. Italy (10.84%), Spain (7.88%) andlan (7.11%) ranked top three in the case atality rate. By March27, the values of five-day moving average Rt in USA, UK, Iran, Spain and France were all more than one. The average daily increase rate in China had changed negative since March 6. The average daily increase rates in the other eight countries ranged from 41.58% to 18.17%, and the trend was slow down from March 20 to 29, among which Germany, Switzerland and Italy had the largest decline of 35.60%, 29.76% and 25.56%, respectively @*Conclusions @#By March 29, the epidemie situation of COVID-19 in China was under controls; the situations in ltaly, Germany and Switzerland tended to be stable; while the situations in USA, UK, Iran, Spain and France maintained an upward tmend.
