"Twenty million Americans get sick from norovirus each year according to data released last week by the Centers for Disease Control (CDC). Often called vomiting illness, it can spread rapidly on cruise ships, and in dormitories and hospitals. Recent data from the CDC shows deaths from gastrointestinal infections have more than doubled and have become a particular threat to the elderly. The virus is shed in the stool of the infected individual, has a short incubation period and can spread quickly if proper hand washing and other measures are neglected."^^<http://www.w3.org/2001/XMLSchema#string>
