The West Coast is getting strict on its quarantine guidelines after California surpasses one million positive COVID-19 cases.

The governors of California, Oregon and Washington state released advisories last week urging travelers to quarantine for 14-days when arriving in each state. Residents of these states are asked to only go out for essential items and avoid out-of-state travel.

Officials confirm that essential travel consists of traveling for work, medical care and critical services. With the approaching holiday season, officials are taking the necessary precautions to help stop the spread of COVID-19. 

California Governor Gavin Newsom said in a statement, “Increased cases are adding pressure on our hospital systems and threatening the lives of seniors, essential workers and vulnerable Californians. Travel increases the risk of spreading COVID-19, and we must all collectively increase our efforts at this time to keep the virus at bay and save lives.”

Although the travel advisory is voluntary, Newsom’s office said in a statement that they officials are “encouraging others to be respectable and be responsible by taking action. Asking people to do the right thing is the most powerful enforcement tool we have.”
