For people worried about traveling into flu-infested areas during the holiday season, the Centers for Disease Control and Prevention has a great map that shows where outbreaks are occurring.
The data is about a week old, with the latest update from the week ending on Dec. 3. But it gives a good sense of where the flu has been reported. According to the most recent numbers, Kansas is among the 19 states where there has not been any influenza activity reported. Thirty states, including Colorado and Nebraska, have reported sporadic flu activity. In Virginia, a flu outbreak has been reported in one region.
