My cousin is presently in Germany visiting her daughter. Her visitor's visa will expire shortly. If no flights are allowed out of Germany or into the U.S., she's likely stuck there. It will be interesting to see how this plays out. While her visitor's visa be extended or will she be forced to fly back to the states and then what happens once she's landed? If she had her druthers, she'd stay there longer. She wisely has no desire to be on a crowded plane for several hours.
May son, who also lives in Germany and is employed by the U.S. government is presently on leave. When that leave expires, it isn't clear what happens. Does he go back to the base he works on which is about 150 miles from where he and his family live, or does he continue to work from home? He's petitioned to be able to come into the office one day a week so he can keep current on his work. My daughter-in-law is able to work from home. One of my granddaughters works in the medical profession. She's be going to work every day. She wears a mask and gloves as protection from potentially infected patients.
When my great-granddaughter is born sometime late in April. Only her mother and one other person will be allowed to attend the birth or visit. There will not be the whole family showing up to see the newborn, as is usually the case.
Life for all of us is going to be disrupted, if it isn't already. It is something we will just have to put up with for our own safety and that of others.
