Biden: I Told Family To Avoid Planes, Subway Over Swine Flu (VIDEO) WASHINGTON Vice President Joe Biden says he's advising his own family to avoid "confined places" -- to stay off commercial airlines and even subways -- because of the new swine flu. Biden said Thursday if one person sneezes on a confined aircraft, "it goes all the way through the aircraft." Going beyond official advice from the federal government, Biden said of his family's personal precautions: "That's me." Asked on NBC's "Today" show whether the government should close the border with Mexico to try to slow the spread of the flu, Biden says health authorities advise that would be impractical because the swine flu has already spread to the U.S. and several other nations. Instead, he says people should focus on confined places where the flu could spread quickly, such as airplanes, malls and classrooms.
