A patient with Coxsackievirus infection is most likely to present with which clinical syndrome?

Coxsackievirus (particularly Coxsackievirus A16 and Enterovirus 71) is the causative agent of Hand, Foot, and Mouth Disease (HFMD). HFMD is a common viral illness primarily affecting children under 5 years old. It presents with: fever, painful oral vesicles/ulcers (on the tongue, buccal mucosa, and hard palate), and maculopapular or vesicular rash on the palms, soles, and buttocks. Herpangina (also caused by Coxsackievirus A, types 2-6, 8, 10) presents with oral vesicles on the posterior oral cavity but without the hand and foot involvement. Both conditions are self-limiting.
