72% of US counties likely have coronavirus epidemics, report says - Business Insider

  • The coronavirus has spread far more widely in the US than the number of confirmed cases indicates, according to a new report from a team of disease modelers at the University of Texas at Austin.
  • Their modeling, which was first reported on by The New York Times, suggested that 72% of the US's 3,142 counties likely already have coronavirus epidemics, even if they don't know it yet.
  • To arrive at their estimates, the UT Austin researchers repurposed a tool they previously used to analyze the Zika virus, another "silent spreader." They applied the framework to calculate the risk of widespread, undetected community transmission of COVID-19 in each US county, based the number of confirmed cases in each county as of April 2.
  • Restrictions were initially limited to counties in southwest Florida where confirmed cases were more highly concentrated.
