In a study that compares rapid antigen and laboratory PCR approaches for COVID-19 serial screening, researchers affiliated with the NIH RADx initiative reported results from 43 people infected with the virus.

NIH researchers report that the prevalence of COVID-19 in the United States during spring and summer of 2020 far exceeded the known number of cases. For every diagnosed COVID-19 case in this time frame, the researchers estimate that there were 4.8 undiagnosed cases, representing an additional 16.8 million cases by July alone.

The CDC, in collaboration with the NIH, has launched an innovative community health initiative called “Say Yes! COVID Test.” Up to 160,000 residents in two US communities will have access to free, rapid antigen tests that they can administer themselves to use three times a week for one month.

An NIH-funded research team has launched a study to assess performance and usability of a smartphone app paired with the Quidel QuickVue At-Home COVID-19 Test, which received FDA emergency use authorization for use with a prescription.

The FDA granted emergency use authorization today for an innovative COVID-19 viral antigen test developed with support from the NIH RADx Initiative.

The COVID-19 Testing Impact Calculator is a free resource that shows how different approaches to testing and other mitigation measures, such as mask use, can curb the spread of the virus in any organization.

NIH, working in collaboration with the Biomedical Advanced Research and Development Authority (BARDA), today announced a third round of contract awards for scale-up and manufacturing of new COVID-19 testing technologies.

NIH has awarded seven contracts to companies and academic institutions to develop digital health solutions that help address the COVID-19 pandemic.

NIH announced $129.3 million in scale-up and manufacturing support for a new set of COVID-19 testing technologies as part of RADx. These tests add to initial awards made to seven companies on July 31, 2020.
