Which of the following conditions is characterized by oral ulcerations and is often caused by viral infections?

Herpangina is characterized by oral ulcerations that are often the result of viral infections, particularly those caused by enteroviruses such as coxsackievirus. This condition typically manifests with painful vesicular lesions and ulcers primarily on the soft palate and uvula, leading to discomfort while eating and swallowing. It predominantly affects children and usually occurs in outbreaks.

The connection to viral infections is crucial, as herpangina specifically arises from these agents and can lead to systemic symptoms such as fever. Recognition of this condition is important for differentiating it from other causes of oral ulcerations, making it a key point in the study of oral manifestations in infectious diseases.
