Full data obtained on 4/4/2020 are shown in Table 1 for the top 50 countries with highest number of COVID-19 cases in the world. Table 2 shows the countries according to number of tests performed per positive diagnosed COVID-19 cases. Table 3 shows population level pandemic projections for cases and deaths according to each individual country's case per test and death per test rate on 4/4/2020 0900 BST. Table 4 shows population level pandemic projections adjusted for the combined case per test and death per test rate of the 15 countries group that have performed at least 100000 tests. Table 5 shows the population level pandemic projections adjusted for the case per test and death per test rate of South Korea. Figure 1 show a scatter plot to show the relationship between the case fatality rate and the testing rate as a percentage of the total population of the country for the countries which have tested at least 1% of their total population. Italy was excluded from this scatter plot as it was an outlier with a case fatality rate of 12.25%.
