Health officials say a Mohave County resident was among those who were on board the Grand Princess cruise ship that was held off the California coast last week.
A release from the county says the individual was among 17 Arizonans on board, all of whom have been asymptomatic so far.
The individual is heading back home, where he or she will self-quarantine for 14 days.
Mohave County Department of Public Health nurses will check on the patient regularly to monitor for signs of COVID-19 and to deliver food and supplies.
