Introduction: Coronavirus disease 2019 (COVID-19) was first identified in December 2019 and has resulted in an ongoing pandemic. This meta-analysis was conducted to investigate the current global incidence and mortality of COVID-19 and also explore the associated factors including geographic variations, transmission scenarios, country economic status, and healthcare performance. Methods: We performed a search in the online databases which reported the most recent number of COVID-19 cases and deaths. The search was conducted in World Health Organization situation report, OurWorldinData.com, and the European Center of Disease Control and Prevention which were based on reports from national authorities by 10:00 CEST, June 2, 2020.Random-effects model meta-analyses and meta-regression analyses were used to generate summary estimates and explore sources of heterogeneity. Results: A total of 215 countries and dependent territories were included in this meta-analysis. The pooled incidence of COVID-19 was 460 per 100,000 people. Daily cumulative index (DCI) was 269.19 cases/day (95% CI 137.74 to 246.18). The overall pooled mortality rate of COVID-19 was 2.7% (95% CI 2.4 to 3.0). Incidence, DCI, and mortality rate were highest in high-income countries and community transmission. DCI and mortality rate had a significant association with the gross domestic product (GDP), percentage GDP spent on total health expenditure, total health expenditure per capita, and population life expectancy. Country universal health coverage was significantly correlated to DCI. Conclusion: To date, 215 countries around the world are affected by COVID-19. Higher income, GDP, and healthcare performance were associated with higher DCI and mortality rate of COVID-19. Funding Statement: None.
