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.

Animal Diseases

The health of animals—pets, farm animals, and wildlife—is linked to the health of humans who share their environment. A small number of the communicable diseases that animals can be infected with are transmissible (under certain circumstances) to people. Contra Costa Public Health monitors the occurrence of several animal diseases with significant human health implications.

Report an Animal Disease


WE RELY ON VETERINARIANS and the public to notify us when they encounter certain diseases or conditions in animals. Reporting this information helps Contra Costa Public Health protect the public from illness.


The state of California requires veterinarians to report certain diseases and conditions the local health department.


Veterinarians are required to report six animal diseases to Contra Costa Public Health:

  • Anthrax
  • Brucellosis (except Brucella canis)

Additionally, veterinarians are encouraged to contact Contra Costa Public Health about outbreaks or unusual occurrences of animal disease.
