California officials are urging residents to limit all non-essential travel to within 120 miles from one’s home and avoid traveling to neighboring states or countries.
Anyone arriving in or returning to the state is urged to self-quarantine for 10 days, the California Department of Public Health (CDPH) said in a statement.
California -- the epicenter of the current coronavirus surge in the United States -- is also discouraging any non-essential visitors from out of state.
The recommendations are not mandatory, but the statement said local officials could consider enacting "measures that are more restrictive than this statewide order."
The department warned that visitors or residents returning to California could introduce new sources of infection, including the new strains of the virus.
“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,” CDPH said.
For reference, the distance from Los Angeles to San Diego is approximately 120 miles. The distance from Los Angeles to San Francisco is approximately 381 miles.
