COVID-19 impacts every corner of the community. Working with partners throughout Santa Cruz County, we have developed a framework to safely move forward that protects residents, aligns with State public health authorities and the governor’s Resilience Roadmap, and is based on measurable objectives to increase community resiliency.

What is SAVE Lives Santa Cruz County?

Recognizing the challenge COVID-19 poses to the community, SAVE Lives Santa Cruz County is a partnership between the County of Santa Cruz and Community Foundation Santa Cruz County designed to facilitate a community-based plan for moving forward. It is based on four principles:

    Until a vaccine and human immunity are in place, we must use the tools we have to slow the spread of COVID-19 and protect lives. These include:
    • Physical distancing measures
    • Expanding public health testing, case investigation, contact tracing and isolation and quarantine capabilities
    • Expanding healthcare capacity and PPE availability
    In order to continue offering services, we recognize changes are necessary to minimize harm. These include:
    • Modify physical distancing measures for businesses, schools, childcare facilities and community
    • Maintain and monitor testing, contact tracing and isolation and quarantine capacities
    • Maintain and monitor public health and healthcare capacities
    Once a vaccine is available, we must:
    • Develop a vaccination plan to coordinate equitable, risk-based distribution
    • Increase capacity for mass dispensing
    • Implement agreements with private and public partners to be dispensing sites
    • Ensure ability to develop and administer therapeutics to meet the demand
    COVID-19 will change the way we function as a community. Our task includes:
    • Elevating readiness for next public health emergency
    • Strengthening Public Health infrastructure and workforce
    • Evaluating and improving Public Health information systems


Santa Cruz County COVID-19 Hospitalization Projections

For current information on hospital usage including ICU beds, please visit the California COVID-19 Hospital data page.

How to read the model: For the actual number of hospitalizations in the past, we use the blue dots. To look at the future, we use the dark blue line and the light blue area. The dark blue line is the most likely number of hospitalizations in the future. Since models are not perfect, the light blue wider area shows the range of likely hospitalizations.”

Why We Forecast Hospitalizations

We all rely on our hospitals to take care of us when we are very ill. If a hospital gets too full, it doesn’t have enough space or staff to care for everyone.

So, it is important to keep track of how many people are staying in a hospital at one time. It is also important to use our forecasts to predict when hospitals might get too full.

When our hospitals start to get too full, we need to take actions to slow the spread of COVID-19.

Tracking and forecasting how many people are in our hospitals help us SAVE Lives in our community.

How to read the plot: The plot shows green (for good) when Rt is below 1 and COVID-19 spread is decreasing. When Rt is above 1 and COVID-19 spread is increasing, the plot is yellow (take caution). The darker line shows the most likely Rt in Santa Cruz county. Since models are not perfect, the shaded areas around the darker line show the range of likely Rt values. Please note that case data from the last 7 days are frequently updated and are excluded from the estimation of Rt.

Rt: COVID-19 Spread in Our Community

The Effective Reproductive Number, shown here as “Rt” helps us understand how fast COVID-19 is spreading in our community. For COVID-19, RRt tells us the average number of people who will contract this disease from each infected person.

For example, if Rt equals 1, each existing infection causes one new infection. An Rt equal to 1 means the disease will stay present and stable in our community.

If Rt is less than 1, each existing infection causes less than one new infection. Therefore, if Rt stays below 1, spread of the disease declines and it eventually leaves the community.

When Rt is more than 1, each existing COVID-19 infection causes more than one new infection. The disease will be transmitted between more and more people and the spread of the disease is growing. If Rt stays greater than 1, it can lead to many challenges, including hospitals not being able to care for everyone who gets sick.

Rt depends on people’s behavior, like wearing a mask or keeping social distance. This is why Rt can change over time. For example, in the plot around March 20th the COVID-19 value for Rt in our county was probably about 2. Then, when many people stayed home through April and May, Rt dropped below 1.

COVID-19 Wastewater Monitoring

Santa Cruz, CA data comes from the City Influent. This trunkline conveys sewage from the incorporated City limits (est population of >70,000).

Santa Cruz County, CA data comes from the Lode Street pump stations, A sewage trunkline conveying sewage from the southern part of the County (Freedom through Live Oak, est population of 80,000). Click here to view the data directly on Verily for more in-depth information.

SARS-CoV-2 Sewage Monitoring Data

SARS-CoV-2 (the virus that causes COVID-19) is shed in feces by infected individuals and can be measured in wastewater. More cases of COVID-19 in the community are associated with increased levels of SARS-CoV-2 in wastewater, meaning that data from wastewater analysis can be used as an indicator of the level of transmission of COVID-19 in the community.

Wastewater analysis measures the levels of non-infectious RNA (Ribonucleic Acid) in wastewater, not the viable virus. There are no known cases of transmission resulting from exposure to wastewater.

Wastewater-based epidemiology (WBE) is the study of a population’s exposure to chemicals or pathogens, like SARS-CoV-2, by measuring their presence in wastewater.

Advantages of WBE

The use of WBE has several potential advantages:

  • It includes asymptomatic individuals and people who are unable or unwilling to obtain clinical tests, for a variety of reasons.
  • It provides a mechanism to monitor the level of community transmission as clinical testing declines, and other, more convenient testing takes place (such as home-based rapid antigen tests) that are not reported to the Public Health Department. Wastewater analysis continues to be a part of our ongoing strategy to monitor the level of community transmission.
  • Wastewater information is available sooner than information from clinical testing, which means that monitoring SARS-CoV-2 in wastewater can serve as an early indicator of increasing or decreasing COVID-19 infections in the community.
    • During an increase, this early information could be used to enhance public health messaging in the affected communities to reinforce safe practices, promote more clinical testing, and highlight strategies the public can take to help stop a surge in new cases.
  • It can help confirm current trends of COVID-19 infections in the community that are based on clinical data.
  • It can increase confidence that clinical testing results are not biased by availability, time lags, and other factors.

This dashboard is updated every Monday and Thursday. Modeling is updated every Wednesday.

Case numbers are an accumulation of cases reported to the Local Health Jurisdiction, and are recorded by episode date. Total known cases of COVID-19 will fluctuate due to adjustments such as jurisdiction transfers and routine data cleaning, which may involve the resolution of existing cases (i.e., probable cases either confirmed or invalidated). Cases will continue to be monitored and are likely to be adjusted further.

Due to known data delays in COVID-19 reporting systems, data is preliminary and modeling is subject to change.
