Which statement best describes the clinical signs of human Salmonella infection?

• A. Acute gastroenteritis (fever, diarrhea, abdominal cramps, vomiting, blood stool)
• B. Meningitis
• C. Chronic liver disease
• D. Rash and itching

Answer: (A)

Salmonella infections most often present as acute gastroenteritis. After ingesting contaminated food or water, the bacteria invade the intestinal lining and trigger inflammation, leading to fever, abdominal cramps, diarrhea (which can be watery and sometimes bloody), and often nausea or vomiting. This gut-focused illness is typically self-limiting in healthy individuals, though dehydration can occur. Meningitis, chronic liver disease, or a generalized rash with itching are not the typical signs of a standard Salmonella infection, though rare complications or specific forms (like typhoid fever from Salmonella Typhi) can show different features. Thus, the classic picture is acute gastroenteritis with fever, diarrhea, abdominal cramps, and vomiting.
