Infectious gastroenteritis caused by Norovirus which broke out in November 2006 has infected more than three million patients within a two-month periode. Their symptoms varied from severe diarrhea, vomiting and fever to digestive disorders due to a slight flu. The author, an otolaryngologist, has examined numerous flu patients who complain of various symptoms and always bears in mind that digestive disorders might result from Norovirus. Warnings of this kind are found in some clinical reports. The present paper suggests that otolaryngologists should be aware that their patients with flu symptoms might have gastroenteritis caused by Norovirus.
