SAN FRANCISCO, Calif. (KRON) — California is among the states hit hardest by the novel coronavirus in the US.

The Centers for Disease Control and Prevention confirmed the state’s first case of COVID-19 on January 26. By February 26, a resident of Solano County became the nation’s first coronavirus patient infected through community-spread.

The number of cases remained fairly low through February, which experts say is due to a lack of testing. California began to see the number of cases climb in early March and reported the state’s first COVID-19 death on March 4.

Below is a county-by-county map with data from the Center for Systems Science and Engineering at John Hopkins University:

KRON4 compiled data from the California Department of Public Health to show the growth of cases in the state.

The coronavirus pandemic is an evolving crisis. This database will be updated once a day when the CDPH sends out the latest numbers.

How People Can Protect Themselves

Every person has a role to play. Protecting yourself and your family comes down to common sense: 

  • Staying home except for essential needs/activities.
  • Practicing social distancing.
  • Washing hands with soap and water for a minimum of 20 seconds.
  • Avoiding touching eyes, nose or mouth with unwashed hands.
  • Covering a cough or sneeze with your sleeve, or disposable tissue. Wash your hands afterward.
  • Avoiding close contact with people who are sick.
  • Staying away from work, school or other people if you become sick with respiratory symptoms like fever and cough.
  • Following guidance from public health officials.

What to Do if You Think You’re Sick

Call ahead: If you are experiencing symptoms of COVID-19 (fever, cough or shortness of breath) and may have had contact with a person with COVID-19, or recently traveled to countries with apparent community spread, call your health care provider before seeking medical care so that appropriate precautions can be taken.
