What are the symptoms of illness from Vibrio in healthy and high risk people?

• A. Healthy: Diarrhea, vomiting, abdominal pain; High risk: sudden chills, fever, shock, skin lesions
• B. Healthy: Rash only; High risk: Sneezing
• C. Healthy: Headache; High risk: Dizziness
• D. Healthy: Cough; High risk: Pain in joints

Answer: (A)

Vibrio infections typically cause gastroenteritis in healthy people, but in high-risk individuals (such as those with liver disease, diabetes, or compromised immune systems) the infection can spread and become life-threatening, with systemic and skin involvement. For someone healthy, the common symptoms are diarrhea, vomiting, and abdominal pain. In high-risk people, the illness can present with sudden chills, fever, shock, and skin lesions. This pattern fits the described scenario best, reflecting the difference between a milder GI illness in healthy individuals and a severe, systemic infection in those at higher risk. The other options describe symptoms not aligned with the typical Vibrio presentation by health status.
