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 for smoke tips and for air quality in your area

About Us


Often called the "best kept secret of Contra Costa County", Contra Costa Health Plan (CCHP) has been serving the health needs for people in the County for 40 years. CCHP was the first federally qualified, state licensed, county sponsored HMO in the United States. In 1973, we became the first county sponsored health plan in California to offer Medi-cal Managed Care coverage and in 1976, we became the first county run HMO to serve Medicare beneficiaries. In the 1980's, we expanded our programs to reach out to county employees, businesses, individuals and families. In 2014 as part of the implementation of the Affordable Care Act, CCHP enrolled over 35,000 newly eligible individuals into Medi-Cal Managed Care and in 2015 over 25,000 more individuals enrolled into CCHP Medi-Cal Managed Care.
