Officials are stepping up their warnings to younger Americans about the coronavirus, because they can more easily spread the virus without having symptoms and now because new evidence shows the potential for some younger people to suffer severely from it. At White House briefings this week, Dr. Deborah Birx, coordinator for the White House's coronavirus task force, has expressed concerns that not everyone is taking social distancing guidance to heart. "We are asking every single American, no matter what your generation, from Z and up to X, and millennials in between, to really ensure that you're following these guidelines," Birx told reporters on Tuesday. "We hear every night of people who are not in work, moving that time into bars and other areas of large gatherings. If we continue with that process, we will fail in containing this virus."
