Breaking News: Health Advisory for Contra Costa County

Last updated: November 16, 2018, 9:52 am

Poor air quality in Contra Costa is expected to continue through the weekend due to the Camp Fire in Butte County. Stay indoors when possible and keep doors and windows closed. Avoid prolonged outdoor activity. Masks are not a substitute for staying indoors. Seek medical attention if you experience symptoms such as difficulty breathing, persistent coughing, wheezing, chest tightness, heart palpitations, nausea, fatigue or light-headedness. Visit baaqmd.gov for air quality information. Visit airnow.gov for current air quality conditions in your zip code. Visit cchealth.org/wildfire for smoke-related health information.

Communicable Disease


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.
