Using ILI surveillance to estimate state-specific case detection rates and forecast SARS-CoV-2 spread in the United States

Category:

Topic:

  • Silverman & Washburne show how they repurposed publicly available CDC influenza-like illness (ILI) outpatient surveillance data to estimate the detection rate of symptomatic SARS-CoV-2 infections. 
  • They noted a surge of non-influenza ILI above the seasonal average that correlated with COVID-19 case counts across the states.
