Norovirus

Another outbreak of the nasty norovirus, a highly contagious stomach bug, has sent a second Caribbean cruise ship home early this week.

Two of the country's most beautiful national parks are reporting an ugly outbreak of illness.

This is turning out to be a miserable winter for staying healthy. First it was the flu epidemic, and now comes word that a new, severe strain of norovirus - also called the winter vomiting bug or the cruise-ship virus - has spread from Australia to Europe to Canada to the U.S.

With the recent outbreak of norovirus aboard two cruise ships, let's take a bit of a look at maintaining health during travel.  Getting out and about is great fun, and with a few bits of choice knowledge, you can make your trip safer as well.

The norovirus -- a nasty little bug that causes stomach upset similar to food poisoning -- sickened passengers and crew on three cruise ships sailing out of Florida and Louisiana this past weekend, requiring the ships to delay departure while they underwent special disinfection.
