Antibody study shows coronavirus infections much higher than previously reported

Data released Tuesday by the Centers for Disease Control and Prevention shows the number of coronavirus cases in different parts of the United States was sometimes 2 to 13 times higher than the reported rates in the areas.

“These data continue to show that the number of people who have been infected with the virus that causes COVID-19 far exceeds the number of reported cases,” Dr. Fiona Havers, the CDC researcher who headed up the study, said. “Many of these people likely had no symptoms or mild illness and may have had no idea that they were infected.”
