Initial COVID-19 infection rate may be 80 times greater than originally reported | Penn State University
UNIVERSITY PARK, Pa. – Many epidemiologists believe that the initial COVID-19 infection rate was undercounted due to testing issues, asymptomatic and alternatively symptomatic individuals, and a failure to identify early cases.
Now, a new study from Penn State estimates that the number of early COVID-19 cases in the U.S. may have been more than 80 times greater and doubled nearly twice as fast as originally believed.
In a paper published today (June 22) in the journal Science Translational Medicine, researchers estimated the detection rate of symptomatic COVID-19 cases using the Centers for Disease Control and Prevention s influenza-like illnesses (ILI) surveillance data over a three week period in March 2020.
