Data Updates from our Epidemiology Team 

We know how important it is for our residents to have access to, and understand, the latest reliable data regarding COVID-19 in our communities. That’s why our epidemiologists are frequently reconciling and evaluating how data is presented. Over the past few days, the team has made some changes to our surveillance page. Here’s a summary of those changes. 

Removal of “Change from yesterday +/-” under Key indicators

  1. This change took effect on March 25 and was removed because with data reporting lags, this number no longer represents a true change since the previous day (as in 15 people were diagnosed since yesterday) and is therefore not as reliable as the updated trend charts. In addition, the frequency of data updates for vaccinations and deaths has changed, so the “change from yesterday” is no longer an accurate way to visualize the burden of COVID-19 infection during low community spread. 
    The changes in daily number of cases, hospitalizations and deaths are still available on respective dashboards for any date rate of interest. By using the date filter, you can visualize the recent change in case count on the COVID-19 cases dashboard, or of deaths and hospital admissions on the COVID-19 Case Disposition dashboard. 

Death Counts are Generated Weekly; Due to surge, reflect a broader time period than week-by-week 

  1. Due to the recent surge in cases and the associated processing needed, recent deaths (ranging from January to March 2022) required more time to review. Therefore, the death count under the COVID-19 Case Disposition dashboard and “Total Deaths” in key Indicators were underreported until March 25th, 2022. Marin HHS finished reviewing and processing these most recent deaths. The death totals on the dashboard are now up to date as of March 25th,2022. 

Vaccine Dashboards Updated Weekly 

  1. As reported on Monday, we’ve shifted to a weekly reporting model for vaccination data. Fewer people are getting “newly” vaccinated, and the vaccination data from California Immunization Registry (CAIR) removes people from Marin into another county whenever they have a newer vaccination, of any type, elsewhere. In addition, CAIR also experienced a data issue when they were adding a new county to the registry. On a couple days, these caused a negative change on “Total Residents Vaccinated” under Key Indicators. By keeping the reporting to a weekly timeframe still provides a progress report without these little adjustments creating confusion. Visit our Marin County COVID-19 Vaccinations page to view dashboards relating to vaccination rates.  

New Dashboard: Wastewater Surveillance 

  1. On March 23, we added a NEW dashboard to monitor our wastewater surveillance efforts. This dashboard is updated weekly on Fridays and shows the average amount of virus (COVID gene copies per milliliter) in five different wastewater collection sites across Marin. This dashboard can be found on our Surveillance page.  

Updated Dashboard for Hospitalizations 

  1. Our dashboard displaying the daily census of COVID-19 patients has been updated! The daily census reflects the total number of COVID-19 patients reported to the California Department of Public Health (CDPH) from Marin's acute care hospitals--MarinHealth Medical Center, Kaiser San Rafael, and Novato Community Hospital. The data is lagged by one-day. From January 1 to March 4, 2022, during the surge of hospitalizations related to the Omicron variant, patients hospitalized due to COVID-19 disease are displayed separately (light blue and yellow lines). The darker blue and orange lines are the CDPH Daily Patient Census, which includes patients hospitalized due to COVID-19 disease as well as patients hospitalized for other conditions who had a positive COVID-19 test. This dashboard can be found on our Surveillance page.  


Expiration Extension for iHealth Test Kits 

Earlier this week, March 29, 2022, the U.S. Food and Drug Administration (FDA) announced a three-month shelf-life extension for the over-the-counter iHealth COVID-19 Antigen Rapid Test. This extension applies to all tests with expiration dates on or before September 29, 2022. Originally this test’s shelf-life was 6 months, so now it has been extended to 9 months. If you have purchased a test kit from this manufacturer and want to check its updated expiration date, you can visit the iHealth website and enter the item’s lot number.
