Salmonellosis: A case of salmonellosis is caused by one of the numerous serotypes of Salmonella bacteria, and is most often manifested by diarrhea, abdominal pain, nausea, and sometimes vomiting. However, asymptomatic cases may occur. A case of salmonellosis may be considered confirmed or probable. A confirmed case has been proven by laboratory testing, while a probable case is symptomatic and can be epidemiologically linked to a confirmed case. Both of these types of cases are counted in the reported case counts.
