Noroviruses, a common cause of gastroenteritis, generate havoc as the nation’s No.1 cause of foodborne disease and epidemic diarrhea. Acute gastroenteritis is the second most frequent cause of illness in the United States, with only the common cold occurring more frequently.  The sharp increase in norovirus outbreaks has been attributed to a new, more aggressive viral strain designated GII.4. Healthcare professionals across disciplines can limit the transmission of norovirus by paying meticulous attention to handwashing and by encouraging coworkers and visitors to do the same. Healthcare professionals should follow the recommended standard precautions or other specific precautions designated for special populations.


The goal of this norovirus continuing education program is to provide nurses, athletic trainers, dietitians, fitness professionals, health educators, and physicians with information about norovirus infection, sometimes called “stomach flu,” “stomach bug,” “24-hour flu,” “infectious diarrhea” or “food poisoning.” After studying the information presented here, you will be able to:
  • Name three reasons why noroviruses are transmitted so easily in closed settings
  • Explain why some people are more likely to become infected with norovirus than others
  • List the clinical criteria used to differentiate norovirus gastroenteritis from bacterial or parasitic gastroenteritis
