High Risk Populations

Who is at higher risk? 

  • Adults 65 years and older 
  • Individuals with a compromised immune system 
  • Individuals with chronic medical conditions like:
    • Heart disease 
    • Lung disease
    • Diabetes
high risk

If you are at high-risk, the California Department of Public Health and the Sierra County Public Health Department strongly recommend you self-isolate to protect yourself and slow the rate of transmission of COVID-19.

 What will self-isolation achieve? 

The elderly (65 and older), those with compromised immune systems and those with chronic medical conditions are at higher risk for complications if contracted COVID-19. The timely implementation of aggressive strategies that create social distance and those that reduce close contact of people has proven effective in prior pandemics at delaying rates of transmission and reducing illness and death.

By decreasing the prevalence of disease across California and in Sierra County we will:

  • Reduce the number of Sierra County residents who contract COVID-19 before an effective treatment or vaccine is available.
  • Protect those most likely to experience severe symptoms, such as older residents and those with underlying chronic conditions.
  • Preserve and protect our health care delivery system, including our health care workforce, so that they can care for the least healthy individuals in the community for any medical condition, not just COVID-19.

What is the role of the community?

Practice Universal Precautions

  • Wash hands with soap and warm water 
  • Avoid touching eyes, nose, or mouth with unwashed hands
  • Practice social distancing 
  • Stay away from work, school, or other people if you become sick with respiratory symptoms like fever and cough


  • Assist those in the community who are being requested to self-isolate, such as the high-risk population

Limit Mass Gatherings

  • Religious services should be temporarily cancelled or have protocols in place to create social distancing and practice universal precautions.  Alternative service options should be provided for the high-risk population.  

How long will these limitations apply?

At this time, it is unknown how long these limitations will apply. As with all guidance that relates to COVID-19 response, Sierra County Public Health will revisit this guidance on a regular basis to evaluate the continued need for it, or any changes to elements of it and continue to adhere to direction from Governor of California and California Department of Public Health.
