What is contact tracing?
Contact tracing is when public health workers identify and notify the people who were exposed to infected people. They let them know that they’ve been in close contact with an infected person, and what to do next to keep themselves and their loved ones safe. Public health departments have used contact tracing for decades to fight the spread of infectious diseases.
How does it work?
Public health workers get in touch with those who have tested positive. They might do this by calling on the phone or sending a short survey by text or email. People who have tested positive may be asked about people they were with who they may have exposed while they were contagious. Public health workers then call or text those close contacts to let them know that they may have been exposed. When they do this, they keep the name of the person who tested positive confidential.
Contact tracing in California
California Connected is our state’s contact tracing program.
By helping infected and exposed people self-isolate or self-quarantine, we can slow the spread of the infection and help avoid outbreaks. This helps California support those who are infected or exposed, while also keeping their loved ones and communities safe from the spread of infection. This also helps our hospitals and healthcare systems manage caring for the patients who develop serious illness. Contact tracing is a necessary activity that allows us to safely reopen schools and businesses.
How you can participate
Contact tracing works when you answer the call or text.
All you have to do is answer the phone call or respond to the text message survey sent by your local health department.
Contact tracing is an anonymous way to do your part. The more people answer the call or text, the more lives and jobs California will save and the faster we can re-open schools and businesses and keep them open. 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 if you do get sick.
The sooner we can reach you, the sooner you can get advice, testing, and the support you need.

Know that you are not alone
Pandemics can be stressful. Fear and anxiety about a new disease and what could happen can be overwhelming and cause strong emotions.
Coping with stress in a healthy way will make you, the people you care about, and your community stronger. See this CDC video about managing anxiety and stress.
If you feel like you need to talk to someone for emotional support, see this list of resources. The California Surgeon General released two playbooks for managing stress and tips for caregivers and kids.
