America Is Reopening. But Have We Flattened the Curve?

How is the outbreak growing?

Seeing the total number of cases over time, on a country-by-country basis, can illustrate how the pandemic is expanding.

These charts show cumulative cases – for instance, the number of people who have ever tested positive for Coronavirus in a given country, regardless of whether they have recovered. An upward bend in a curve can indicate either a time of explosive growth of Coronavirus cases in a given country, or a change in how cases are defined or counted.

Comparing across countries can also show where the pandemic is growing most rapidly at any point in time.

Cumulative Cases By Days Since 50th Confirmed Case

Charting the outbreak day by day in each country allows us to see the succession of events as a global story. Because the epidemic began at different times in different countries, viewing each country’s curve from the same starting point can allow us to more easily compare countries.

The starting point for this chart is the day on which the 50th case was confirmed in each country, with the trend lines following the number of days since that event. As with the graph above, use the drop-down menus to visualize confirmed cases or deaths (totals or per 100,000 population), and linear or logarithmic scale.

As more data about the impact of the Covid-19 pandemic becomes available, it is increasingly clear that the disease is hitting the most vulnerable and disadvantaged populations in the U.S. the hardest. Although racial and ethnic information is currently available for only about 35% of the total deaths in the U.S., even this limited sample shows that Black Americans and other historically disadvantaged groups are experiencing infection and death rates that are disproportionately high for their share of the total population. For example, while Black Americans represent only about 13% of the population in the states reporting racial/ethnic information, they account for about 34% of total Covid-19 deaths in those states. Asian Americans and Latinx Americans also show elevated impacts in some regions.
