I. What does the trip code with an asterisk mean?

City names marked with an * (asterisk) indicate that there are currently medium or high risk areas in the cities you have visited in the last 14 days, but it does not mean that you have actually visited these medium and high risk areas.

How is "via" defined on the itinerary card? A "pass through" means that you stayed at a place for more than 4 hours and at the same time opened the trip code on your cell phone, and the system automatically recorded it as a pass through or a visit.
