Protect Yourself From Flu


Last updated: January 19, 2018, 12:14 pm

California and Contra Costa are seeing high levels of flu activity. We remind the community to take the following steps to prevent the spread of flu.

  • Get your flu vaccine
  • Clean hands often with soap and water or with hand sanitizer
  • Cover your coughs and sneezes
  • Stay home when you’re sick

People with flu like symptoms should call their health plan's Advice Nurses to get help with self-care or to help them decide if they need to visit an urgent care clinic, make an appointment with their health care provider or go to an emergency room. Rarely is emergency room needed for flu or respiratory issues.

Contra Costa Health Plan members and Contra Costa residents who do not have health coverage can call 1-877-661-6230 and select option 1 to speak to an Advice Nurse.
