\n The number of coronavirus cases in the US during March may have been 80 times greater than original estimates \u2014 amounting to over 8.7 million new cases that health officials and the public never knew existed, according to a new study.<\/p>\n

Researchers led by epidemiologists from Penn State University studied surveillance data on influenza-like illnesses from the US Centers for Disease Control and Prevention and noticed a huge spike in cases that month, they reported Monday in the journal Science<\/a> Translational Medicine.<\/p>\n

\u201cThe findings support a scenario where more than 8.7 million new SARS-CoV-2 infections app<\/a>eared in the US during March and estimate that more than 80% of these cases remained unidentified as the outbreak rapidly spread,\u201d wrote Justin Silverman of Penn State, Alex Washburne of Montana State University and colleagues at Cornell University and elsewhere, CNN reported.<\/p>\n

At the time, when there was a shortage of coronavirus testing kits, about 100,000 cases of the disease had been officially reported. As of Tuesday, about 2.3 million cases and over 120,000 deaths have been reported.<\/p>\n

\u201cWe analyzed each state\u2019s (influenza-like illness) cases to estimate the number that could not be attributed to influenza and were in excess of seasonal baseline levels,\u201d said Silverman, assistant professor in Penn State\u2019s College of Information Sciences and Technology<\/a> and Department of Medicine.<\/p>\n

\u201cWhen you subtract these out, you\u2019re left with what we\u2019re calling excess ILI \u2013 cases that can\u2019t be explained by either influenza or the typical seasonal variation of respiratory pathogens,\u201d he said in a news<\/a> release.<\/p>\n

\u201cAt first I couldn\u2019t believe our estimates were correct,\u201d Silverman added. \u201cBut we realized that deaths across the U.S. had been doubling every three days and that our estimate of the infection rate was consistent with three-day doubling since the first observed case was reported in Washington state on January 15.\u201d<\/p>\n

The researchers found that the excess in cases of influenza-like illnesses, or ILI, showed a nearly perfect correlation with the spread of the coronavirus around the US.<\/p>\n

\u201cThis suggests that ILI data is capturing COVID cases, and there appears to be a much greater undiagnosed population than originally thought,\u201d Silverman said.<\/p>\n

The researchers estimated infection rates for each state, noting that those showing higher per-capita rates of infection also had higher per-capita rates of a surge in excess ILI.<\/p>\n

Their data showed rates much higher than initially reported but closer to those found once states began completing antibody tests for the disease.<\/p>\n

In New York, for instance, the researchers\u2019 model suggested that at least 9 percent of the state\u2019s population was infected by the end of March. After the state conducted antibody testing on 3,000 people, they found a 13.9 percent infection rate, or 2.7 million New Yorkers.<\/p>\n

\u201cThe US-wide ILI surge appeared to peak during the week starting on March 15 and subsequently decreased in numerous states the following week; notable exceptions are New York and New Jersey, two of the states that were the hardest hit by the epidemic, which had not started a decline by the week ending March 28,\u201d the researchers wrote.<\/p>\n

The findings suggest another way of thinking about the outbreak.<\/p>\n

\u201cOur results suggest that the overwhelming effects of COVID-19 may have less to do with the virus\u2019 lethality and more to do with how quickly it was able to spread through communities initially,\u201d Silverman said.<\/p>\n

\u201cA lower fatality rate coupled with a higher prevalence of disease and rapid growth of regional epidemics provides an alternative explanation of the large number of deaths and overcrowding of hospitals we have seen in certain areas of the world,\u201d he added.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n
