What you need to know

  • Primary herpetic gingivostomatitis (PHGS) typically has a prodrome of 2-4 days, and consists of fever, malaise, headaches, and cervical lymphadenopathy before generalised gingival inflammation and ulceration occur

  • PHGS is often a self-limiting infection that resolves in 10-14 days. Be aware of more serious complications of a herpes simplex infection, including erythema multiforme, aseptic meningitis, and encephalitis

  • Treatment with oral aciclovir is recommended within five days of prodromal signs and symptoms

Non-specific prodromal symptoms followed by oral inflammation and ulceration in a child of this age are characteristic of primary herpetic gingivostomatitis (PHGS). Although PHGS is self-limiting and is rarely associated with severe complications, the child’s lack of appetite and malaise, and the painful appearance of the oral tissues can distress the parents and child. This article offers an overview of the typical presentation of PHGS, the differentials to consider, and management advice for parents.

PHGS is an acute infectious disease affecting the oral cavity and is classically caused by herpes simplex virus type 1 (HSV-1).1 The virus is transmitted through direct contact with a lesion or infected body fluids (eg, saliva) and frequently affects children aged 2-5 in the form of PHGS.123 Infection before the age of 6 months is rare, owing to circulating maternal antibodies which are present in 70-80% of the adult population.1234 The absence of passive immunity can result in early contraction of HSV-1, which can be a potentially serious complication in a young infant.
