Cases of highly contagious norovirus are climbing once again across the U.S. - just in time for the holiday travel season.
Recent data from the Centers for Disease Control and Prevention showed that the number of tests coming back positive for the potentially deadly viral infection has now reached 14 percent, doubling from just three months ago. Of the more than 2,700 tests conducted for the week of November 15, about 380 cases of norovirus were diagnosed.
