CDPH and the CDC recommend delaying travel until persons are fully vaccinated, because travel increases the chance of getting and spreading COVID-19. Travel threatens to exacerbate community spread within and beyond 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, including Sars-CoV2 variants of concern.
With over 18 million vaccine doses administered statewide, vaccines have made a difference and overall disease trends have improved dramatically over the past ten weeks. Case rates, test positivity, transmission rate, hospitalizations and ICU admissions have all declined since the winter surge. While we have made great progress, many states and countries are experiencing increasing levels of transmission, and it is imperative that California continue to take steps necessary to curb the spread of COVID-19 and contain new sources of infection until we can achieve higher levels of vaccination in California and beyond. The State is issuing the following recommendations, which supersede the Travel Advisory issued on April 1, 2021
i "Non-essential travel" includes travel that is considered tourism or recreational in nature.
ii "Essential travel" is travel associated with the operation, maintenance, or usage of critical infrastructure or otherwise required or expressly authorized by law (including other applicable state and local public health directives), including work and study, critical infrastructure support, economic services and supply chains, health, immediate medical care, and safety and security. Persons who routinely cross state or country borders for essential travel do not need to quarantine.
