My husband and I are traveling, and we are both over 60. We asked our doctor what she thought about travel. Her main comments were, "Stay out of crowds", "Wear a mask", "Wash your hands a lot," and "don't touch your face."
As for your daughter going back to college, even some of the colleges are trying to decide what to do. My SIL teaches at a midwestern college in Kansas, and they are still "on the fence" about classes this fall. She's decided that if she goes back to teach (and in-person is best for her field), she will be taking a shower when she gets home every day. Your daughter is probably in less danger than some of her professors and asst profs.
