New UW Study Will Track COVID-19 Prevalence In Washington

SEATTLE, WA — A new study beginning this month will provide thousands with COVID-19 antibody tests in Washington, as part of a major research effort through the state Department of Health, UW Medicine and the Paul G. Allen Family Foundation.

The state's latest undertaking is designed to give researchers a better idea of the virus's prevalence in Washington, especially among people and groups that may not otherwise seek testing. That includes people who may not have had symptoms, residents in more rural areas and minority populations that have been disproportionately impacted by the virus.

A similar study conducted by the Centers for Disease Control and Prevention tested blood samples from 16,000 people in 10 regions between late March and early May. The CDC found virus rates to be approximately 10 times higher on average, indicating the true number of infections is likely well above reported totals.

According to UW Medicine, researchers will work closely with local public health agencies to enlist a diverse group of 7,000 participants in urban and rural areas — all of whom will receive a diagnostic COVID-19 test, followed by three rounds of antibody tests over the next eight months.

UW Medicine expects to have the first round of data released in the fall, helping shape the state's evolving assessment of virus activity moving forward.

"Data is a crucial tool in helping us fight this pandemic and safely reopening our economy," Gov. Jay Inslee said in a statement. "This study and partnership will provide vital insights about the trajectory of COVID-19 in Washington, informing our response and allowing us to better protect Washingtonians."

Beyond helping provide a clearer picture of infection rates, the longer duration of the study will help researchers learn how long COVID-19 antibodies are present after infection. Using that information, the state can adjust its safety guidance in the months ahead.

The project is funded by a $3.4 million grant from the Paul G. Allen Family Foundation. UW Medicine said participants will get results back within a week, and the first round of data should be released publicly by September.
