Time (Days Since First Cases)

At this time, the number of cases in the world is still rapidly rising. Although some countries initally hit hard are starting to return to normal life, such as China and South Korea, the total world case count will continue to rise as COVID-19 rapidly spreads in other countries. The projected SIR model can also be applied to the entire world on a larger scale to some extent. However, some differences must be noted. Firstly, spikes and plateaus in case count can be much more volatile across the world than just the United States due to the fact that different countries have different testing availablities. Additionally, the spread of COVID-19 between countries will be determined by international travel restrictions, whereas the United States is unlikely to close state borders.
