It was a breezy afternoon when Claire, a working mother of three, rushed into my clinic with her youngest child, Lily. Lily, a bubbly three-year-old usually full of energy, sat lethargically on her mother’s lap, her face flushed, and her small hands clasped tightly.
“Dr. Priya, I’m so worried. She’s been feverish and hasn’t eaten much for the past couple of days,” Claire began, brushing back Lily’s curly hair. “This morning, I noticed these red spots on her hands and feet, and her mouth seems sore. She keeps crying whenever I try to feed her.”
As I listened to Claire, my mind quickly turned to a likely diagnosis—Hand, Foot, and Mouth Disease (HFMD). This common viral infection, particularly prevalent among young children, often leaves parents like Claire feeling distressed. I reassured her, “Let’s take a closer look at Lily and talk through what’s happening.”
What is Hand, Foot, and Mouth Disease?
HFMD is a mild yet highly contagious viral illness caused by the Coxsackievirus, a member of the Enterovirus family. It primarily affects children under the age of 10, although teenagers and adults can occasionally catch it too. The virus spreads through close contact, respiratory droplets, or exposure to infected feces, making childcare centers and schools common sites of outbreaks.
As I explained this to Claire, she nodded. “Lily’s older brother had something similar a couple of years ago, but it wasn’t this bad,” she said.
“Every case is different,” I replied. “But the good news is that HFMD is usually mild and resolves on its own.”
A Closer Look at the Virus
The Coxsackievirus, specifically Coxsackievirus A16, is the most common cause of HFMD, although Enterovirus 71 can also be responsible. Outbreaks tend to occur during warmer months and often spread rapidly among groups of children due to their close contact and shared environments.
Symptoms of Hand, Foot, and Mouth Disease
HFMD typically starts with a prodromal phase, where children feel generally unwell before specific symptoms appear. Lily’s fever, fatigue, and irritability were consistent with this early stage.
Key symptoms include:
- Fever: Often the first sign, as Claire had noticed.
- Sore Throat and Malaise: Children may seem irritable or fatigued.
- Loss of Appetite: Soreness in the mouth can make eating uncomfortable.
- Skin Rash: Small red spots that may blister, appearing on:
- Palms and soles of feet
- Around the mouth and gums
- Sometimes on the buttocks or genital area
While examining Lily, I noticed clusters of blisters on her hands and feet, as well as ulcers in her mouth. “These ulcers can be painful, which is why she’s finding it hard to eat,” I explained to Claire.
A study published in Pediatrics found that 90% of HFMD cases present with both oral ulcers and characteristic rashes, making these hallmark signs for diagnosis.
How is HFMD Spread?
HFMD is highly contagious, spreading via:
- Direct Contact: With saliva, mucus, or fluid from the blisters.
- Respiratory Droplets: When an infected person coughs or sneezes.
- Contaminated Surfaces: Toys, utensils, or other shared items.
Children are most infectious during the first week, even before symptoms fully appear. “It’s likely Lily picked this up at daycare,” I told Claire. “But don’t worry—most kids recover quickly with proper care.”
According to the Centers for Disease Control and Prevention (CDC), the virus can persist in a child’s feces for weeks after recovery, emphasizing the importance of hygiene to prevent further spread.
Is HFMD Serious?
While HFMD is generally mild, certain complications can occur, such as:
- Dehydration: A common concern when children refuse to drink due to mouth pain.
- Nail Shedding: Temporary shedding of nails weeks after recovery.
- Rare Complications: In rare cases, severe strains of the virus can cause meningitis or encephalitis.
Claire looked alarmed. “Should we be worried about those complications?”
“They’re very rare,” I reassured her. “With Lily’s symptoms, the focus should be on keeping her hydrated and comfortable.”
A large-scale study in Southeast Asia found that Enterovirus 71-associated HFMD had a higher risk of neurological complications compared to cases caused by Coxsackievirus.
Treatment for Hand, Foot, and Mouth Disease
“There’s no specific cure for HFMD,” I explained. “It’s caused by a virus, so antibiotics won’t help. The goal is to manage symptoms and keep Lily comfortable.”
At-Home Care:
- Fever Management: Paracetamol or ibuprofen can help reduce fever and relieve pain.
- Mouth Ulcer Care:
- Rinse with saline or warm salt water.
- Avoid acidic or spicy foods that might irritate sores.
- Offer soothing foods like yogurt, smoothies, or ice cream.
- Hydration: Encourage fluids such as water, milk, or broth. For very young children, ice pops can be a fun way to stay hydrated.
Studies show that cold foods can reduce the pain of mouth ulcers in children with HFMD, improving their willingness to eat and drink.
Hygiene Measures:
To prevent spreading HFMD within the household, I recommended:
- Frequent handwashing with soap and water.
- Disinfecting shared surfaces and toys.
- Avoiding close contact, like kissing or hugging.
What About School or Daycare?
“Should I keep her home from daycare?” Claire asked.
“Yes,” I replied. “Although the virus can remain in the body for weeks, Lily should stay home until her fever resolves and the blisters dry up.”
The Centers for Disease Control and Prevention (CDC) advises parents to notify schools or daycare centers to prevent further spread during outbreaks.
How Common is HFMD?
HFMD is a global illness but tends to spike in warmer months. In Australia, where Claire and Lily live, outbreaks often occur during spring and summer. Research indicates that children aged 6 months to 5 years are most susceptible due to their developing immune systems.
A 2021 study estimated that HFMD affects nearly 200 million children worldwide annually, with higher prevalence in Asia-Pacific regions.
Follow-Up and Recovery
I scheduled a follow-up to ensure Lily was recovering well. “Most cases clear up within 7 to 10 days,” I said. “If she shows signs of dehydration or worsening symptoms, bring her back immediately.”
Claire thanked me and sighed with relief. “I feel better knowing what’s going on. I just want her to be comfortable again.”
