Hand, Foot, and Mouth Disease

Examine oral intake, urine output, mucous membranes, perfusion, and vital signs at presentation. Oral ulcer pain, dysphagia, drooling, and poor intake can cause dehydration; in typical HFMD, dehydration is the most frequent complication. PubMedPubMedInfectious Diseases Patients unable to maintain hydration, with clinical dehydration, or with inadequate outpatient observation should receive acute care assessment for fluid support.

Treat altered mental status, lethargy, severe headache, neck stiffness, weakness, seizure, hypotension, or hypoperfusion as a complication pathway rather than uncomplicated HFMD. EV-A71 outbreaks have been associated with a high incidence of central nervous system complications. WHOWHOA Guide to Clinical Management and Public Health Response ... When meningitis or encephalitis is suspected, obtain CSF enterovirus PCR as the key etiologic test while evaluating and managing the patient according to the broader CNS infection syndrome.

A febrile child with vesicles plus hypotension or hypoperfusion requires evaluation for bacterial meningitis or sepsis as well as enteroviral disease; do not attribute shock physiology to uncomplicated HFMD. PubMedPubMedInfectious Diseases

Make a clinical diagnosis when the syndrome includes oral vesicles that ulcerate and a painful erythematous vesicular eruption on the hands and feet; lesions may also involve the groin or buttocks. PubMed+1PubMedInfectious DiseasesPubMedViral Infections of the Oral Mucosa - StatPearls - NCBI Bookshelf Oral lesions can precede the cutaneous eruption and commonly involve the buccal mucosa, palate, and tongue.

Obtain real-time PCR from a vesicle or lesion swab when morphology is atypical, diagnosis would change management, severe disease raises concern for enteroviral complication, or strain identification is important to a public-health investigation. Lesion PCR can detect coxsackievirus or enterovirus, and multiplex real-time PCR assays have been developed for prevalent HFMD-associated enteroviruses.

Serology is not sensitive for acute diagnosis; IgG may be used to monitor recovery, and some centers use serology to distinguish EV-A71 from coxsackievirus because of prognostic implications.

Interpret virologic detection in context. Enterovirus can be detected in stool for approximately 6 weeks after infection and oropharyngeal shedding is generally less than 4 weeks; therefore, stool positivity alone may not establish that a current atypical eruption is caused by HFMD.

HFMD is an enteroviral syndrome most often associated with coxsackievirus A16 and EV-A71; coxsackievirus A6 is also a common causative serotype and is linked to atypical presentations, including cases in adults.

Separate HFMD from isolated herpangina by skin involvement. Herpangina produces fever and painful posterior oral lesions, whereas HFMD produces oral vesicles or ulcers together with painful lesions on the hands and feet and may include groin or buttock involvement. PubMedPubMedInfectious Diseases This distinction matters because neither syndrome requires routine antiviral treatment, but absent acral disease should prompt reassessment of the diagnosis rather than reflexive confirmation testing. publications aap+1publications aapC1 PAGE.inddPubMedInfectious Diseases

When vesicles, ulceration, or distribution are not characteristic, prioritize disorders for which treatment or infection-control implications differ. The differential includes varicella-zoster virus and herpes simplex virus; microscopy of a vesicle biopsy or scraping is described as a means of distinguishing these infections from HFMD. PubMedPubMedHand, Foot, and Mouth Disease - StatPearls - NCBI Bookshelf Atypical HFMD can be clinically broad, particularly with coxsackievirus A6, so lesion PCR is most useful when it resolves that specific diagnostic fork.

Direct management toward maintaining hydration and reducing the functional impact of oral pain. HFMD treatment is supportive, and uncomplicated illness generally resolves within days to two weeks without residual sequelae. publications aap+2publications aapC1 PAGE.inddPubMedHand, Foot, and Mouth Disease - StatPearls - NCBI BookshelfPubMedInfectious Diseases Reassess rather than simply extend supportive care when intake declines, dehydration develops, fever or systemic illness is disproportionate to the mucocutaneous syndrome, or neurologic findings emerge.

Do not use routine enterovirus-directed antiviral therapy for uncomplicated HFMD. In immunocompromised patients, IVIG has been described as a consideration to reduce illness duration and viral shedding; this is not presented as routine treatment for immunocompetent children with classic disease. PubMedPubMedInfectious Diseases Consultation is appropriate when immunocompromise coexists with severe, persistent, or complicated enteroviral disease.

Set a short-interval monitoring plan around oral intake and neurologic status rather than rash resolution. The rash and oral lesions usually last 7 to 10 days, but a patient whose ability to drink worsens during that interval needs reassessment for dehydration.
