    ObjectivesAs a global pandemic is inevitable, real-time monitoring of transmission is vital for containing the spread of COVID-19. The main objective of this study was to report the real-time effective reproduction numbers (R(t)) and case fatality rates (CFR) in Europe.MethodsData for this study were obtained mainly from the World Health Organization website, up to March 9, 2020. R(t) were estimated by exponential growth rate (EG) and time-dependent (TD) methods. 'R0' package in R was employed to estimate R(t) by fitting the existing epidemic curve. Both the naïve CFR (nCFR) and adjusted CFR (aCFR) were estimated.ResultsWith the EG method, R(t) was 3.27 (95% confidence interval (CI) 3.17-3.38) for Italy, 6.32 (95% CI 5.72-6.99) for France, 6.07 (95% CI 5.51-6.69) for Germany, and 5.08 (95% CI 4.51-5.74) for Spain. With the TD method, the R value for March 9 was 3.10 (95% CI 2.21-4.11) for Italy, 6.56 (95% CI 2.04-12.26) for France, 4.43 (95% CI 1.83-7.92) for Germany, and 3.95 (95% CI 0-10.19) for Spain.ConclusionsThis study provides important findings on the early outbreak of COVID-19 in Europe. Due to the recent rapid increase in new cases of COVID-19, real-time monitoring of the transmissibility and mortality in Spain and France is a priority.Copyright © 2020 The Authors.
