Question

Coxsackievirus A16 causes:

• A. Yellow fever
• B. Hand-foot-mouth disease
• C. Rocky mountain spotted fever
• D. Encephalomyocarditis

Answer 1

The Correct Option is B

Step 1: The clue is the agent, Coxsackievirus A16, a member of the enterovirus family, so the answer must be an enteroviral exanthem. Step 2: That maps directly to hand-foot-mouth disease, a childhood vesicular eruption over the palms, soles and oral mucosa, classically driven by Coxsackie A16 (with enterovirus 71 a close second). Step 3: Transmission is faeco-oral and respiratory, with the typical prodrome of low-grade fever and feeling unwell before the rash appears on hands, feet and mouth. Step 4: Ruling out distractors, yellow fever traces to a mosquito-borne flavivirus, Rocky Mountain spotted fever to a tick-borne rickettsia, and encephalomyocarditis to its own picornavirus, none of which is Coxsackie A16. \[\boxed{\text{Hand-foot-mouth disease}}\]
