No discussions occurred between WHO and the CDC about providing tests to the United States, WHO spokesperson Tarik Jasarevic told CNN on Tuesday, and WHO did not offer coronavirus tests to the CDC.
The United States, Jasarevic confirmed, doesn't ordinarily rely on WHO for tests because the US typically has the capacity to manufacture its own diagnostics.
On January 17, WHO published a
protocol from German researchers with the instructions necessary for any country to manufacture coronavirus tests.
That same day, a top US health official said that the CDC had developed an early version of its own test -- not relying on any protocols published by the WHO.
"We actually do have laboratory diagnostics here at CDC that are stood up,"
said Dr. Nancy Messonnier, director of the National Center for Immunization and Respiratory Diseases.
Testing began at the CDC, and on February 5, the agency
announced it would begin shipping test kits to public health labs around the country. Just a day later, the World Health Organization
said it had already shipped 250,000 tests to more than 70 laboratories around the world.
As WHO shipped hundreds of thousands of tests, broader US testing struggled to begin. Days after CDC's tests shipped, some labs reported that the test kits
were not working as expected, which eventually required tests be re-manufactured.
