Viruses cause about 70% of episodes of infectious diarrhea in the pediatric age group. [13] Rotavirus is a less common cause in adults due to acquired immunity. [27] Norovirus is the cause in about 18% of all cases. [28] Generally speaking, viral gastroenteritis accounts for 21–40% of the cases of infectious diarrhea in developed countries. [29]
Listeriosis can cause serious illness in pregnant women, newborns, adults with weakened immune systems and the elderly, and may cause gastroenteritis in others who have been severely infected. The incubation period can vary from three to 70 days. [6]

More than 70% of the diners at an adjacent table fell ill; at a table on the other side of the restaurant, the infection rate was still 25%. The outbreak was attributed to a Norwalk-like virus (norovirus).
In people over the age of 45 with more than two weeks of the above symptoms, the odds for peptic ulceration are high enough to warrant rapid investigation by esophagogastroduodenoscopy. [citation needed] The timing of symptoms in relation to the meal may differentiate between gastric and duodenal ulcers.

[16]In adults, a clinical prediction rule found the best signs to be significant diarrhea ("new onset of more than three partially formed or watery stools per 24-hour period"), recent antibiotic exposure, abdominal pain, fever (up to 40.5 °C or 105 °F), and a distinctive foul odor to the ...
Over the following decades, Crohn's disease was recognized as affecting various parts of the gastrointestinal tract, with reports of involvement from the esophagus to the colon. This period also marked the identification of skip lesions—areas of healthy bowel between diseased sections—adding to the understanding of the disease's pathology.
For this observational study, researchers analyzed data from the U.K. Biobank and Whitehall II study of more than 20,000 adults in the U.K. 70 years and older with or without previous ...
