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.

Mosquito-borne Illnesses

Some mosquitoes carry diseases that infect people when they bite us. The diseases can vary by species – there are different kinds of mosquito – and by region.

In Contra Costa County, the only disease that mosquitoes are known to give humans is West Nile Virus.

The best way to avoid mosquito-borne illnesses is to avoid bites.

  • Use insect repellant
  • Cover up – wear long-sleeved shirts and pants, especially at dawn and dusk
  • Use screens on windows or doors when it gets warm, or just use air conditioning

Contra Costa residents can also help to reduce the local mosquito population.

  • Keep mosquitoes from breeding in your home or garden
  • Report neglected (green) swimming pools, ponds or troughs of stagnant water
  • Get help if you notice unusual mosquito activity
