Boston Globe - 03/17/2020
Another scientist who spoke to the Globe, Samuel Scarpino, a Northeastern University professor who specializes in infectious disease modeling, said he used an algorithm developed by an epidemiologist at Notre Dame University that calculates the United States has only detected between 1 of every 10 cases and 1 in 30 cases, due to its low rate of testing compared to other countries. He said Massachusetts likely has 1,970 to 5,910 or more actual cases.
