Introduction: There is much debate about the growing incidence and fatality of COVID-19 in the entire globe that whether this incidence and fatality of the pandemic are really and statistically varying among the countries particularly with different health status and economic development. Objective: Based on the above research problem, the paper investigates the variations in average death, infection rate, fatality rate and mortality rate and looks into the statistical significance of their growth trends among different group of countries. Methods: The data on total confirmed cased and the total number of death for 178 countries used in this research has been collected from the World Health Organization (WHO) Coronavirus Disease (COVID-19) Dashboard. The paper explains the current status estimating of average death, incidence rate, fatality rate and mortality rate. Moreover, the paper also investigates the statistical significance of average death, incidence rate, fatality rate and mortality rate applying compound monthly growth rate and one-way ANOVA. Results: The paper reveals that average death and infection rate of COVID-19 in all countries are increasing irrespective of economic and other categories. However, the fatality rate is found to be very low in relatively low level-income countries as well as low human developed countries. Moreover, one-way ANOVA results also show that infection and mortality rates are significantly very high among high-income countries and high Human Development Index (HDI) level countries. But fatality rate which is significantly high among low-income countries and very low among Global Health Security (GHS) least-prepared countries. Conclusion: The average death and infection rate of COVID-19 in all countries are increasing irrespective of economic and other categories but the fatality rate is found to be very low in relatively low level-income as well as low HDI level countries.
