White House health advisor Dr. Anthony Fauci said Tuesday there are early signs that a coronavirus outbreak could be brewing in Indiana, Ohio, Tennessee and Kentucky. 

The so-called positivity rate, or the percentage of tests run that are positive, appears to be rising in those states — an early indication that the outbreak is worsening, Fauci said.
