Spread of COVID-19

Gating Criteria Targets: 

  • Rate of spread, 10-day rolling average (statewide and regionally): 1.05 or less
  • NM COVID-19 daily cases, by specimen collection date, 7-day rolling average: 168 cases or less. (There is a lag in case reporting).

In all three graphs a downward trend is a positive development. NM aims to have a rate of spread as well as a daily case count that is as low as possible.

Also known as the R_effective and effective reproduction number, rate of spread is one measure of COVID-19 viral spread in a community. The rate of spread illustrates the mean number of secondary COVID-19 cases produced by one COVID-19 case.

NM evaluates the rate of spread regularly to understand how well the state’s organizational and individual social distancing measures are working to diminish transmission of the virus. Specifically, the rate of spread is calculated in two formats: 1) a statewide rate of spread; and, 2) regional rates of spreads. Understanding how the rate of spread varies and evolves regionally is critical in responding to community-specific needs and challenges.

Although not a gating crtieria, mobility data is provided. Tracking aggregated, anonymized mobility provides insights into changes in behavior in response to policies aimed at addressing the COVID-19 pandemic. The data illustrates movement trends over time statewide, NMDOH region, and at individual county-level.
