Unhealthy Air Quality Across Contra Costa County

Contra Costa Health Services (CCHS) recommends people in all parts of the county stay indoors with doors and windows closed whenever possible today due to poor air quality.


Air quality in all parts of the county has been measured at unhealthy levels as a result of smoke from large fires burning in California and other western states. Everyone should avoid contact with the smoke and minimize time spent outdoors, especially older adults, people who are pregnant, and people who have asthma, lung or heart disease. 


Using a face covering is not an effective substitute for staying indoors in a space with filtered air. Face coverings used to protect against the spread of COVID-19 are not effective protection against exposure to wildfire smoke.


People with asthma should continue to follow their asthma plan, and those with chronic lung or heart disease should continue to take their medications regularly. Symptoms such as difficulty breathing, chest pain or chest tightness may require immediate medical attention. Call 911 if you experience these symptoms.
