Contact tracing is an important step in slowing the spread of COVID-19. It’s when health workers notify you that you’ve been in contact with an infected person, and you should also get tested. Public health departments have used contact tracing for decades to fight infectious disease. 

Introducing California Connected, our state’s contact tracing program.

Connected California

Under this program, health workers will talk to those who have tested positive. They’ll alert anyone they may have exposed, keeping names confidential. They’ll check symptoms, offer testing, and discuss next steps like self-isolation and medical care.

By finding spread patterns quickly, we slow infection and help avoid outbreaks. This lets California keep healthcare needs below capacity and safely reopen business.

All you have to do is answer a phone call

Contact tracing is an anonymous way to do your part. The more people answer the call, the more lives and jobs California saves. Your information is always kept confidential.

Early awareness helps you protect your friends and loved ones from exposure. And early medical care can improve your outcome.

The sooner we can reach you, the sooner you can get advice, testing, and support.

Is the information I provide confidential?

Yes. Your identity and health information is always kept private. It will not be shared with anyone who may have been exposed. No one will ask about your immigration status during testing, care or follow-up calls. You will never be asked for your Social Security number or payment information.

California’s strict privacy laws protect all your information. California Connected maintains data with strict privacy and security storage standards. The data is only collected and stored for use by local and state public health departments.

Tips to protect others around you

If you find out you have COVID-19, it’s important to quarantine yourself from others so they don’t get sick. Try to stay in a separate room and use a separate bathroom. Disinfect frequently-touched surfaces, or have your caregiver do so. 

People you live with are close contacts and should get tested.

Support if you test positive

Your local public health department can connect you to 

  • Testing
  • Medical care
  • Housing if you need it to self-isolate.

If you work, your employer may be required to provide you with paid sick leave. See this list of employee paid leave rights, ensured by the federal Families First Coronavirus Response Act (FFCRA).
