The actual number of coronavirus infections in the U.S. reached nearly 53 million at the end of September and could be approaching 100 million now, according to a model developed by government researchers.

The model, created by scientists at the Centers for Disease Control and Prevention, calculated that the true number of infections is about 8 times the reported number, which includes only the cases confirmed by a laboratory test.

Preliminary estimates using the model found that by the end of September, 52.9 million people had been infected, while the number of laboratory-confirmed infections was just 6.9 million, the team reported in the Nov. 25 issue of the journal Clinical Infectious Diseases.
