COVID-19 testing in the United States
testing for COVID-19 in the United States of America

COVID-19 testing in the United States can identify whether a person is infected with SARS-CoV-2, the virus which causes COVID-19. This helps health professionals ascertain how bad the epidemic is and where it is worst. The accuracy of national statistics on the number of cases and deaths from the outbreak depend on knowing how many people are being tested every day, and how the available tests are being allocated.
Timeline
January 2020
While the WHO opted to use an approach developed by Germany to test for SARS-CoV-2, the United States developed its own testing approach. The German testing method was made public on January 13, and the American testing method was made public on January 28. The WHO did not offer any test kits to the U.S. because the U.S. normally had the supplies to produce their own tests.
The United States had a slow start in widespread SARS-CoV-2 testing. From the start of the outbreak until early March 2020, the CDC gave restrictive guidelines on who should be eligible for COVID-19 testing. The initial criteria were (a) people who had recently traveled to certain countries, or (b) people with respiratory illness serious enough to require hospitalization, or (c) people who have been in contact with a person confirmed to have coronavirus.
February 2020
In February, the U.S. CDC produced 160,000 SARS-CoV-2 tests, but soon it was discovered that many were defective and gave inaccurate readings.
