Breaking News: Health Advisory for Contra Costa County

Last updated: November 10, 2018, 12:38 pm

The Bay Area Air Quality Management District reports that parts of our county have unhealthy air due to smoke. Please follow the following tips to protect yourself and your loved ones. Everyone, especially children, should reduce outdoor activity. Active children and adults, and people with respiratory disease such as asthma, should avoid prolonged outdoor activity. Masks are not a substitute for staying indoors. Masks such as the N-95 are not effective for untrained users and may be dangerous for people with lung or heart conditions. N-95 masks may be helpful for people who must work outdoors if properly fitted. Employees should work with their employers for direction on when/how to use N-95 masks. Seek medical attention if you experience symptoms like repeated coughing, difficulty breathing, wheezing, chest tightness, palpitations, nausea, fatigue or lightheadedness. Visit cchealth.org for smoke tips and airnow.gov for air quality in your area

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.
