The Marin County COVID-19 Status Update is now publishing five days a week (Monday through Friday) and as needed, in order to share important news and resources in our battle against COVID-19 and to keep our economy running. We remain here for you.


Weekly Blueprint Update: Marin Remains in Tier 2

Today, California Department of Public Health (CDPH) provided its weekly update on the Blueprint for a Safer Economy, a statewide plan for reducing COVID-19 and keeping Californians healthy and safe.  As part of this process, CDPH assesses indicators that capture disease burden, testing, and health equity.  This assessment happens weekly on Mondays and CDPH releases updated tier assignments on Tuesdays at around 12-noon.

CDPH confirmed Marin County’s placement in Tier 2 (red status) for a fifth straight week. CDPH’s October 13 assessment for Marin County includes:

  • Testing Positivity: 1.5%  (decrease of 0.3% since last assessment)
  • Adjusted Case Rate: 4.0   (no change)
  • Health Equity Quartile Test Positivity Rate: 2.7%  (decrease of 0.4%)

The following table outlines the requirements for case rates, test positivity rates, and quartile test positivity rates for each tier status. Currently, two of Marin’s three measurements qualifies for Tier 3 (orange status):

Marin County Current Tier Status



Tier 1

Tier 2

Tier 3

Tier 4

Marin County


Adjusted Case Rate per 100,000

> 7

4 to 7

1 to 3.9

< 1



Overall Test Positivity Rate

> 8%

5% to 8%

2% to 4.9%

< 2%



Equity Metric: Quartile Test Positivity Rate

> 8.0%

≤ 8.0%

≤ 5.2%

≤ 2.1%



In general, for a County to advance to a less restrictive tier, it must (1) have been in the current tier for a minimum of three weeks; and (2) meet criteria for the next less restrictive tier for all three measures for the prior two consecutive weeks in order to progress to the next tier.

For Marin to officially achieve Tier 3 (orange status), two things need to happen: (1) the adjusted case rate must equal or fall below 3.9; and (2) Marin’s data must remain within the Tier 3 range for two weeks. If Marin’s data continues to improve, we could achieve Tier 3 status as early as October 27.  However, that means we must continue to work as a community to slow the spread of COVID-19.



Update from Marin’s Public Health Officer

This morning, Dr. Matt Willis provided a brief update to the Marin County Board of Supervisors regarding Marin’s COVID-19 activity, including a decreasing rate of cases among skilled nursing facilities, Marin’s projected trajectory within the Blueprint for a Safer Economy, an update on schools reopening and community outbreak response, and more.

In Other News… (Non-COVID Updates)

While the following is not related to COVID, it is news from Marin County's Emergency Operations Center that we thought you should know about.


Red Flag Warning Issued Through Friday

National Weather Service has issued a Red Flag Warning for higher elevation areas of Marin County from Wednesday morning (5am) to Friday morning (11am). A Red Flag Warning means that critical fire weather conditions are expected during this time frame for strong wind gusts and hot, dry conditions. Residents are advised to exercise extreme caution during the Red Flag Warning because a simple spark could cause a major wildfire, including the use of equipment and machinery as well as smoking.

Beware of Hot Temperatures this Week

With high temperatures expected this week, here are a few tips to be prepared. Heat affects everyone differently. Extremely high or unusually hot temperatures can affect a person’s health, especially when outdoors for long periods of time. Those most vulnerable to extreme heat include older adults, people with chronic medical conditions or mental health conditions and the socially isolated.

During a heat wave, residents should take the necessary precautions to prevent serious health effects for heat-related illnesses. View some of the resources below for tips to stay cool during warm weather.

Take the Time to Prepare for a Future Public Safety Power Shutoff

Fall is Public Safety Power Shutoff (PSPS) season. PSPS events are called during times of dry, hot weather with strong winds that pose significant fire risk. Pacific Gas and Electric Company (PG&E) will proactively turn off power in these areas to prevent any electrical infrastructure -caused fires. Currently a PSPS event is forecast for the Northern California region: Marin County is NOT within the scope of this PSPS event.  However, as many of us know fire season is far from over, so this first PSPS event is a reminder to prepare for a future extended outage.

The “COVID-19 Data Update” section of yesterday’s status update displayed incorrect numbers within the “change since last status update” column. The web version of the October 12 Status Update has been updated to reflect the cumulative numbers for October 10-12.  All other numbers included in the “COVID-19 Data Update” section were correct.
