The United States has failed to deploy adequate testing for the presence of the coronavirus SARS-CoV-2 during the Covid-19 pandemic and has been unable to avoid continued spread of the virus. In this report, the authors explain why such testing is an essential factor in efforts to control the pandemic, why adequate testing has been difficult to achieve, and why the United States has not met the challenge. They conclude by recommending ways to provide more extensive testing in this and future epidemics.

The world is now in the midst of a once-in-a-century global health pandemic that threatens the lives and livelihoods of billions. This coronavirus transcends borders and nationalities, and until a vaccine is found, a cluster of cases in any one country will endanger the health and safety of people everywhere. For this reason, there has rarely been a time in which the fates of the world's nations were so clearly linked and where American leadership and purposeful international coordination were so urgently required.
