Variants of concern in Shasta County
Because just a small fraction of cases are tested for variants and there is a lengthy delay in results from the state laboratory, it is impossible to know how many variant cases are in Shasta County. The state's Tracking Variants page explains what variants are, what we know about them and how the proportion has changed over time. All four known variants of concern found in the state - alpha, beta, gamma and delta - have also been identified in Shasta County. Statewide, more than 82% of the sequenced specimens are now delta, and it is expected that most cases in Shasta County are delta.
* CDC measures county levels of COVID-19 transmission by calculating two rates — case rate and positivity rate.
The CDC case rate is calculated as the total cases received over a 7-day period per 100,000 persons, with a 2-day lag in data. Shasta County calculates the case rate in the same way, yet with only a 1-day lag in data.
The positivity rate is the percentage of tests that are positive in the past 7 days.
