Herpetic gingivostomatitis often presents in young children and is the most common presentation of primary HSV infection in this age group. The typical presentation is a child with fever, decreased oral intake, malaise, fussiness, drooling, and erythematous gums with painful erosions or vesicular lesions often found within the anterior two-thirds of the mouth and on the labial and gingival mucosa. Symptoms may last up to three weeks. Treatment is largely supportive, focusing on hydration and pain control. Oral acyclovir may also be considered in some cases. Following the primary infection, the virus remains dormant in the trigeminal nerve until reactivation.
