(Reuters) - The U.S. Centers for Disease Control and Prevention (CDC) plans a nationwide study of up to 325,000 people to track how the new coronavirus is spreading across the country into next year and beyond, a CDC spokeswoman and researchers conducting the effort told Reuters.
The CDC study, expected to launch in June or July, will test samples from blood donors in 25 metropolitan areas for antibodies created when the immune system fights the coronavirus, said Dr. Michael Busch, director of the nonprofit Vitalant Research Institute.
