and HSV-2. HSV-1 is predominantly responsible for oral, facial and ocular infections whereas HSV-2 is responsible for most genital and cutaneous lower herpetic lesions. Both HSV-1, and HSV-2 can be the cause of herpetic gingivostomatitis, although HSV-1 is the source of infection in around 90% of cases. Herpetic gingivostomatitis infections can present as acute or recurrent. Acute infection refers to the first invasion of the

Pathophysiology

Herpetic gingivostomatitis originates from a primary infection of HSV-1. The series of events that take place during this infection include replication of the

Differential diagnosis

Diagnosis of HG is very much clinically based. Therefore, it is imperative to rule out other diseases that present similarly, bearing in mind the past medical history of the patient. Some differential diagnoses to bear in mind when considering herpetic gingivostomatitis are: #

Teething Teething is the process by which an infant's first teeth (the deciduous teeth, often called "baby teeth" or "milk teeth") appear by emerging through the gums, typically arriving in pairs. The mandibular central incisors are the first primary te ...

in infants: A study mentioned that "primary tooth eruption begins at about the time that infants are losing maternal antibody protection against the herpes virus. Also, reports on teething difficulties have recorded symptoms which are remarkably consistent with primary oral herpetic infection such as fever, irritability, sleeplessness, and difficulty with eating." Another study highlighted that "younger infants with higher residual levels of antibodies would experience milder infections and these would be more likely to go unrecognized or be dismissed as teething difficulty." #

Herpangina Herpangina, also called mouth blisters, is a painful mouth infection caused by coxsackieviruses. Usually, herpangina is produced by one particular strain of coxsackie virus A (and the term "herpangina virus" refers to coxsackievirus A), but it can ...

: It is a disease that is caused by the Coxackie A virus rather than a herpes virus. In herpangina, ulcers are usually isolated to the soft palate and anterior pillar of the mouth. In herpetic gingivostomatitis, lesions can be found in these locations, but they are almost always accompanied by ulcerations on the gums, lips, tongue or buccal mucosa and/or by hyperemia, hypertrophy or hemorrhage of the gums. # Hand Foot and Mouth Disease: Similar to herpangina, hand foot and mouth disease occurs predominantly in children. It is caused by Coxsackie A and B virus, and lesions or
