Walgreens launches COVID-19 index to advance rapid detection of Omicron and track variant activity by state

Jan. 24, 2022

The Walgreens COVID-19 Index, a new interactive tracking tool from Walgreens, powered by testing data from Aegis Sciences Corporation, is among the first to uniquely identify the spread of current and emerging variants in near real-time. 

New data from the Walgreens COVID-19 Index shows more than 95% of all positive COVID-19 cases are presumed to be the Omicron variant. The data reinforces the importance of vaccinations and testing in helping to mitigate the spread of COVID-19.

Data captured in the Walgreens COVID-19 Index can track the spread of the Omicron variant within 24 to 48 hours, more quickly than other methods. In addition to a national view, data can be reviewed by state. The Walgreens COVID-19 Index is based on proprietary data from PCR testing services administered by Walgreens and performed by its testing partner Aegis Sciences.

Based on data analyzed as of Jan. 18, the following types of insights are available from the Walgreens COVID-19 Index:

  • Nationally, more than 95% of all positive cases are presumed to be the Omicron variant
  • Top states for COVID-19 positive rates are Alabama, Florida, Georgia, Mississippi, South Dakota, Nevada and Texas, which all have COVID-19 positivity rates over 45% of those tested
  • Top states for confirmed Delta case prevalence are Maine (43.5%), Kansas (36.5%), Iowa (29.2%), New Mexico (25.2%), Oklahoma (24.2%), Indiana (23.6%) and Utah (23.5%)
