Management of Hand, Foot, and Mouth Disease (HFMD)
Hand, foot, and mouth disease (HFMD) is a self-limited viral illness that primarily requires supportive care focused on symptom management, hydration, and pain relief. 1, 2, 3, 4
Clinical Presentation and Diagnosis
HFMD typically presents with:
- Low-grade fever
- Painful oral ulcerations/enanthem
- Maculopapular or papulovesicular rash on hands and soles of feet
- Symptoms in children under 5 years of age (most common demographic)
Atypical presentations may include:
Management Approach
Supportive Care
Hydration
- Ensure adequate fluid intake
- Consider cold liquids, popsicles, or ice cream to soothe oral pain and maintain hydration
- Avoid acidic, spicy, or hot foods/beverages that may exacerbate oral pain
Pain Management
Oral Care
- Gentle mouth rinses with warm salt water
- Soft diet to minimize discomfort from oral lesions
When to Consider Additional Interventions
- Most cases resolve within 7-10 days without sequelae 1, 4
- Seek medical attention for:
- Signs of dehydration (decreased urine output, dry mucous membranes)
- Persistent high fever
- Neurological symptoms (headache, neck stiffness, altered mental status)
- Respiratory distress
Special Considerations
- Enterovirus A71 (EV-A71) can cause more severe disease with neurological and cardiopulmonary complications 2, 3
- Intravenous immunoglobulin should be considered for severe/complicated cases 2
- Currently, no specific antiviral agents are approved for HFMD treatment 2, 3
Prevention
Handwashing is the most effective prevention method 4
Disinfection of potentially contaminated surfaces and fomites
Isolation of infected individuals, particularly from:
- Schools
- Daycare centers
- Other settings with vulnerable populations
In high-risk areas (particularly Asia), EV-A71 vaccination may be available 3
Follow-up
- Routine follow-up is not necessary for uncomplicated cases
- Parents should be educated about:
- Expected disease course (7-10 days)
- Potential for nail changes weeks after resolution
- When to seek medical attention for complications
Key Pitfalls to Avoid
- Misdiagnosing atypical presentations, especially in children with atopic dermatitis
- Using oral lidocaine, which is not recommended
- Failing to recognize signs of severe disease requiring hospitalization (particularly with EV-A71)
- Unnecessary antibiotic use, as HFMD is viral in etiology
- Inadequate attention to hydration status, especially in young children with painful oral lesions
Remember that while HFMD is typically mild and self-limited, early recognition of severe cases is essential to prevent complications and mortality, particularly in outbreaks caused by more virulent strains.
