The norovirus is known as the winter vomiting bug in England. It mutates into new strains and spreads around the globe every year. The virus can cause both vomiting and diarrhea simultaneously. It is not fatal but it can cause severe dehydration which can lead to a dangerous situation for the elderly and compromised patients. The virus is not airborne but it spreads easily through contact with surfaces contaminated with the norovirus, such as door handles, counters and toilets. It can also be spread during food preparation.

The CDC has an information page on the norovirus. Here is our coverage:
