As a result, they are warning people who are ill with vomiting or diarrhea not to go to work, school, or attend day care while they are having symptoms.
State Epidemiologist Dr. Megan Davies said Wednesday that washing your hands frequently and thoroughly with soap and water is the most effective way to protect yourself and others against norovirus. Hand sanitizers alone are not as effective against this particular bug.
Davies says noroviruses are easily transmitted by touching a contaminated surface as well as by direct contact or by eating food or drinking liquids that have been contaminated. It is difficult to kill with normal cleaning and disinfecting procedures.
Symptoms include nausea, vomiting, diarrhea and stomach cramping. Some may have fever, chills, headache, muscle aches and a general sense of tiredness. The symptoms can begin suddenly and an infected person may go from feeling well to very sick in a very short period of time. In most people, the illness lasts for about one or two days.
