Communicable Disease

COVID-19 Information

Communicable Disease Programs fight the spread of contagious diseases in Contra Costa County. We work to contain diseases by:

  • Investigating who is sick and who else might get sick
  • Offering vaccines
  • Providing case management services to those who are sick
  • Ordering lab tests to confirm the presence of a disease or virus
  • Educating health providers and the public
  • Collecting data on diseases

We also play a critical role in planning how to protect people in case of a public health emergency such as a flu pandemic.
