Input: 29 Background: Our understanding of the corona virus disease 2019 (COVID-19) continues to 30 evolve. However, there are many unknowns about its epidemiology. 31 Purpose: To synthesize the number of deaths from confirmed COVID-19 cases, incubation 32 period, as well as time from onset of COVID-19 symptoms to first medical visit, ICU admission, 33 recovery and death of COVID-19. Data Synthesis: Out of 1675 non-duplicate studies identified, 57 were included. Pooled mean 41 incubation period was 5.84 (99% CI: 4.83, 6.85) days. Pooled mean number of days from the 42 onset of COVID-19 symptoms to first clinical visit was 4.82 (95% CI: 3.48, 6.15), ICU admission 43 was 10.48 (95% CI: 9.80, 11.16), recovery was 17.76 (95% CI: 12.64, 22.87), and until death 44 was 15.93 (95% CI: 13.07, 18.79). Pooled probability of COVID-19-related death was 0.02 (95% 45 CI: 0.02, 0.03). 46 Limitations: Studies are observational and findings are mainly based on studies that recruited 47 patient from clinics and hospitals and so may be biased toward more severe cases. 48 We found that the incubation period and lag between the onset of symptoms and diagnosis 50 of COVID-19 is longer than other respiratory viral infections including MERS and SARS; 51 .
