I have prepared two graphs using data available on April 19th, 2020 from the Our World In Data resource.
1) The first graph illustrates the United States COVID-19 fatalities from April 1 to April 19th compared to total World fatalities from this virus. These are based on confirmed case data.
On April 1st, the U.S fatalities were less than 10% of World fatalities. As of April 19th, U.S fatalities have increased to 25% of World fatalities.
2) The second graph compares the fatalities over time for many countries including the United States, Canada, UK, France, Germany, Spain, Italy, Brazil, China, India, South Korea. The useful information here for the U.S. is to note that the rate of fatalities in the United States has increased dramatically in just the last week and is the greatest rate worldwide as of April 19th.
