As of Sep. 29, 2020, employees in Pima County, Arizona who travel to any high-risk COVID-19 area, whether state-to-state or international, will not be permitted to return to work for 14 consecutive days after returning home, and will be required to quarantine.
In a memorandum signed by Pima County Administrator Chuck Huckelberry, he stated, "If an employee travels to any high risk destination they will be required to quarantine for 14 days upon their return and are required to use vacation time. Where the employee does not have sufficient vacation time to cover the 14-day quarantine period, the time will be unpaid."
If there are extenuating circumstances that lead to the employee’s need to travel to a high risk area, the employee may be allowed to telecommute during the 14-day period with approval from the county- if possible. The memo said that determinations on whether travel is considered high risk can be reviewed online.
The Center for Disease Control and Prevention has previously issued advice that “COVID-19 risk in most countries is high and travelers should avoid non-essential travel to high-risk destinations." Based on its proximity to Arizona, this includes travel to Mexico.
