New research studies early stages of coronavirus outbreak to re-evaluate rate of initial spread in U.S.

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 Preventions influenza-like illnesses (ILI) surveillance data over a three week period in March 2020.
We analyzed each states ILI cases to estimate the number that could not be attributed to influenza and were in excess of seasonal baseline levels, said Justin Silverman, assistant professor in Penn States College of Information Sciences and Technology and Department of Medicine. When you subtract these out, youre left with what we're calling excess ILI cases that can't be explained by either influenza or the typical seasonal variation of respiratory pathogens.

He gave a few benchmarks to check to see if his estimate was a reasonable one. Each bench mark was met.
This was at the time when everyone was watching IHME's estimate of 60,000 deaths, and this guy said it would be 120,000 by June and would continue to rise after that, and actually speed up.
It made me look into IHME which, it turned out, was based on absolutely ridiculous assumptions.
I posted this guy's article and people yelled at me and told me I was a ghoul who just wanted more deaths.
But if we go by that guy's estimates, the numbers will keep climbing for a long time to come.
