Iceland has 364,000 inhabitants. Currently, roughly 10% of them are aware of whether or not they have COVID-19. This is due to a massive undertaking by Kári Stefánsson, MD, Dr. Med., the co-founder, president, and CEO of deCODE genetics—a population genetics powerhouse that has routinely produced new discoveries in fields such as genomic architecture, cancer genetics, and mental illness. Now, deCODE has combined the most intensive targeted testing and general screening of any population to date for SARS-CoV-2.
