California Department of Public Health
The incidence of COVID-19 is increasing in many states and countries, even as California continues to grapple with its own surge of COVID-19 cases. Persons arriving in California from other states or Californians returning from other states or countries could introduce new sources of infection (potentially including new strains of the SARS-CoV-2 virus) to California. Intra-state travel, likewise threatens to exacerbate community spread within California—particularly because travel itself (especially the use of shared conveyances in air, bus, or rail travel) can increase a person's chance of spreading and getting COVID-19. Postponing travel and staying home is the best way to protect yourself and others from COVID-19.
