NORTHERN CALIFORNIA – Three counties in the North State will move into more restrictive tiers in the state’s Blueprint for a Safer Economy.

Trinity, Modoc, and Siskiyou counties are moving from the yellow tier and into the more restrictive orange tier, according to the state's website.

Trinity County has moved into the orange tier as the test positivity and case rates met the requirement for a more restrictive tier. This goes into effect Nov. 11 with a three-day transition - meaning that businesses and other sectors will be required to implement the guidance under the orange tier, Saturday morning, according to Marcie Cudziol, Trinity County Public Health Director.

For the last several weeks, Modoc County remained in Tier 4, the yellow tier, of the state’s system. However, in the last week, Modoc County experience a higher case rate of COVID-19 and as a result, landed them in the orange tier.

In a press conference Tuesday, California Health and Human Services Secretary Dr. Mark Ghaly provided an update on the coronavirus in California.

Gov. Gavin Newsom on Monday said California is seeing an increase in coronavirus cases that may be partially linked to Halloween.

Newsom warned that coronavirus case numbers, the positivity rate, hospitalizations and intensive care cases all have reached their highest level in months.
