The United States and the European Union have comparable population sizes, but the trajectories of their COVID-19 outbreaks have been vastly different. New data released by the European Center for Disease Control and Prevention shows that while there are around 4,000 new COVID cases in the EU each day, the United States is now recording more than 30,000 new cases of the virus each day – eight times higher than Europe. At least 23 US states have reported significant upticks in new daily COVID-19 cases in recent days, raising fears of an approaching “second wave” of infection. And while some politicians in the US have ascribed the difference to discrepancies in testing, a close analysis shows that the United States and the EU are conducting roughly the same number of tests per million people. Here’s a look at the seven-day rolling average of new COVID cases in the EU and the US since March.
