Salmonellosis is a symptomatic infection caused by bacteria of the Salmonella type. There are two species of Salmonella : Salmonella bongori and Salmonella enterica with many subspecies. Efforts to prevent the disease include the proper washing, preparation, and cooking of food. Salmonellosis is one of the most common causes of diarrhea globally. After a short incubation period of a few hours to one day, the bacteria multiply in the small intestine , causing an intestinal inflammation enteritis.

Background: The early detection of enteric infections in older adults is challenging because typical signs and symptoms of disease may be less common, absent, or overlooked. Understanding illness characteristics of enteric infections among older adults could improve the timeliness and accuracy of clinical diagnoses, thereby improving patient outcomes and increasing cases reported to surveillance. Results: A significant negative correlation was found between all symptoms and increasing age group, except for bloody diarrhea in cases of acute gastroenteritis. Conclusions: Although older adults are more likely to have severe illness and be hospitalized, we found that the proportion of persons reporting symptoms typically associated with enteric infections decreases with age. These findings have implications for clinical recognition and treatment of gastrointestinal illness, as well as for public health research.
