Ukrainian guest workers returning from other European countries wait at the border crossing into Ukraine in Zahony, northeastern Hungary, Monday, March 30, 2020. As pedestrians may not cross at this border station, Ukraine sends buses to the border to transport its citizens into the country. The Ukrainians are returning because of the restrictions imposed to curb the coronavirus pandemic. The new coronavirus causes mild or moderate symptoms for most people, but for some, especially older adults and people with existing health problems, it can cause more severe illness or death.
