The study aims to look at antibody levels for 18 months, to determine whether they wane over time.
The novel coronavirus has infected around 1.5 million people in the United States and killed nearly 90,000, according to a Reuters tally.
The CDC study will test blood from 1,000 donors in each of the 25 metro areas monthly, for 12 months. Researchers will then test blood from another 25,000 donors at the 18-month mark. Samples will come from"regular, altruistic people" who come in to donate blood, Busch said.Some public health officials have complained that the CDC has lagged on research and guidance for local governments trying to cope with the pandemic.
News of the study brought Willis some reassurance. “Partial answers and preliminary results are better than nothing when you have a decision to make” that could affect lives, he said, like when to reopen parks and businesses. The CDC's Nordlund said the study"is indicative of how leaders across the federal government are working collaboratively with partners in academia and in blood donation and testing industries" to monitor COVID-19.
She added that blood donor results can be used by CDC to form estimates about the broader population through statistical methods."This has been done with West Nile virus, Zika, and other emerging infectious diseases," she said.The six metropolitan areas being surveyed in the precursor study are New York, Seattle, the San Francisco Bay Area, Los Angeles, Boston and Minneapolis, said Dr. Graham Simmons, another Vitalant researcher involved in the project.
