We are still going, but having just gotten back from a two week Christmas trip to London at the height of its breakout, I'm planning to take similar precautions. We basically wore N95 masks everywhere including outside, ate outside, limited all indoor activities (meaning lots of long walks around parks and no museums, etc.), and really kept a low profile. It will be harder to do at WDW, and a N95 isn't going to work for the races, but I'm going to do my best. The numbers in Florida look horrible though.
