How COVID-19 Transmission Levels Are Determined

The Centers for Disease Control and Prevention (CDC) now provides a COVID Data Tracker with an Integrated County View. This tool provides an integrated view of key data for monitoring the COVID-19 pandemic in the United States and categorizes all U.S. counties according to Levels of Community Transmission.

The four Levels of Community Transmission and the indicators that determine each Level are:

  • Low Transmission (Blue)
    • County has 0 - 9.99 total new cases per 100,000 persons in the past 7 days
    • Total percentage of positive reported COVID-19 tests (NAATs*) from the past 7 days is between 0 - 4.99%
  • Moderate Transmission (Yellow)
    • County has 10 - 49.99 total new cases per 100,000 persons in the past 7 days
    • Total percentage of positive reported COVID-19 tests (NAATs) from the past 7 days is 5 - 7.99%
  • Substantial Transmission (Orange)
    • County has 50 - 99.99 total new cases per 100,000 persons in the past 7 days
    • Total percentage of positive reported COVID-19 tests (NAATs) from the past 7 days is 8 - 9.99%

*Nucleic Acid Amplification Tests (NAATs) are a type of viral diagnostic test used to detect COVID-19. These types of tests are commonly used at COVID-19 Testing sites and are used to detect the COVID-19 virus in specimen collections from the upper or lower respiratory tract. Additional information about NAATs is available on the CDC's website.
