Rapid Covid-19 tests are being deployed by the millions across the nation. The federal government is sending these tests, which can provide results in minutes, to states for educators, students, nursing home patients, first responders, and other sites.
That’s a good thing. But in a rush to get individual test results, we’re making a dangerous public health mistake: We’re losing critical data about Covid-19.
For months, the U.S. has struggled to get accurate information about Covid-19 cases and testing about different demographic groups. As rapid tests surge — and are performed at sites that don’t follow specific Covid-19 data reporting processes — even more information will be lost.
Accurate data are essential for fighting public health crises like Covid-19. Policymakers need complete, timely information about who is getting the disease to track its spread, identify hot spots, and form effective, equitable solutions. Without data, public health strategies will be haphazard and ineffective.
The Covid-19 pandemic has been a data horror story from the beginning. For months, Americans struggled to get Covid-19 tests, leaving cases of the infection undetected. The data that did exist were woefully incomplete, often lacking important information like a patient’s race and ethnicity.
Data collection has improved since then, but is still lacking. The Centers for Disease Control and Prevention website has race and ethnicity data only for half of Covid-19 cases. And the Trump administration is under investigation for tampering with the CDC’s Covid-19 reports.
Without significant changes, rapid tests will make this data deficit worse.
Laboratories are required to provide extensive data to accompany Covid-19 tests. According to federal guidance published in June, they must collect and report for each test demographic information such as the patient’s age, race, ethnicity, sex, and ZIP code.
Those are sound reporting requirements. But thousands upon thousands of testing sites nationwide are beginning to operate outside of laboratory facilities and are not equipped to comply with state and federal reporting regulations. That includes the vast majority of nursing homes — major hot spots for Covid-19 — as well as many urgent care and physician offices. It also includes unconventional sites like community testing pop-ups.
So a site could test hundreds of people in a day and not report comprehensive data to local and federal authorities. And if reporting does occur, it could take a while to be entered into a digitized system. That means missing crucial data, particularly information on racial inequities.
Gaps in data reporting will become more common in the months to come. Rapid at-home Covid-19 tests that give on-the-spot results will soon hit the market. These tests provide immediate results, but it’s unknown if they will require people to report their results or demographic information to health departments. That means we could lose millions of data points about Covid-19.
To be sure, quick test results are critically important to combat Covid-19. But those tests should come with the requirement to report comprehensive, accurate data back to local or state public health agencies.
We should be moving forward on data collection efforts, not backward. Fortunately, several legislators and organizations are leading the way. Sen. Elizabeth Warren (D-Mass.) and Rep. Ayanna Pressley (D-Mass.), for example, with others have proposed several bills aimed at accurate, timely data collection. The Data: Elemental to Health Campaign aims to secure $100 million in federal funding over 10 years for the CDC and state, local, tribal, and territorial health departments to modernize health data and create a more effective data system for public health.
And the We Must Count coalition — a collection of racial and health equity organizations for which I serve as a senior adviser — is pushing for uniform data collection and reporting on Covid-19 testing, cases, and health outcomes disaggregated by race, ethnicity, socioeconomic status, and other factors.
We must stop at nothing to get accurate data about the results of Covid-19 tests and other aspects of the pandemic. Otherwise, we will lose our battle against it.
