What are four common clinical signs of human infection with Salmonella enteritidis?

• A. Fever, Nausea, Vomiting, Severe diarrhea
• B. Fever only
• C. Nausea and Vomiting
• D. Severe diarrhea only

Answer: (A)

Recognizing the symptom pattern of Salmonella enteritidis gastroenteritis is the main idea. This organism often triggers an acute inflammatory response in the gut with fever as the body’s systemic reaction. The damage to the GI lining commonly causes nausea and vomiting, while inflammation and increased intestinal secretions lead to frequent, often watery diarrhea. Having fever together with upper GI symptoms (nausea and vomiting) and a prominent lower GI symptom (severe diarrhea) reflects the typical clinical picture seen with this infection, so this combination is the best fit for four common signs. Fever alone misses GI involvement; nausea and vomiting without diarrhea omits a major symptom; diarrhea alone omits the systemic and other GI signs. This cluster also highlights dehydration risk from fluid losses, which is an important consideration in management.
